(Operations)

An operation of a remote-controlled robot control system according to a first embodiment will be described below.

FIG. 11 is a flowchart illustrating an example of an operation of the robot control terminal 3. In a case where the functional configuration of the robot control terminal 3 is realized by a computer as illustrated in FIG. 10, a processing program necessary for executing the control processing illustrated in the flowchart is stored in the program memory 302, and the processor 301 executes the program, thereby operating as the robot control terminal function unit 30 of the robot control terminal 3 as illustrated in FIG. 7.

The processor 301 of the robot control terminal 3 first functions as the patrol prediction/task setting unit 31, and determines whether a pre-set operation from a nurse by the keyboard/mouse 341 connected to the input/output interface 305 is performed (step S301). In a case where it is determined that there is no pre-set operation (NO in step S301), the processor 301 functions as the call reception function unit 321 and determines whether a call is received via the communication interface 304, that is, whether there is a call from the remote-controlled robot 1 (step S302). In a case where it is determined that there is no call (NO in step S302), the processor 301 shifts to the processing of step S301 described above. Thus, the processor 301 waits for a pre-set operation or a call.

(1) Pre-Set Work

In a case where it is determined that the pre-set operation has been performed in the step S301 (YES in step S301), the processor 301 acquires pre-set contents indicating the contents of the pre-set operation performed by the nurse by the keyboard/mouse 341, and stores the content in the temporary storage unit 3031 of the data memory 303 (step S303). Then, the processor 301 transmits the pre-set content to the robot control server 2 by the communication interface 304 (step S304). Next, the processor 301 shifts to the processing in step S301 described above.

FIG. 12 is a flowchart illustrating an example of an operation of the robot control server 2. In a case where the functional configuration of the robot control server 2 is realized by a computer as illustrated in FIG. 9, a processing program necessary for executing the control processing illustrated in the flowchart is stored in the program memory 202, and the processor 201 executes the program, thereby operating as the robot control server function unit 20 of the robot control server 2 as illustrated in FIG. 3.

The processor 201 of the robot control server 2 first functions as the patrol prediction management unit 21 and determines whether pre-set contents are received from the robot control terminal 3 by the communication interface 204 (step S201). In a case where it is determined that the pre-set content is not received (NO in step S201), it is determined whether a schedule acquisition request for requesting transmission of a patrol schedule is received from the remote-controlled robot 1 by the communication interface 204 (step S202). In a case where it is determined that the schedule acquisition request is not received (NO in step S202), the processor 201 functions as the task function/measurement data management unit 22, and determines whether the task function acquisition request is received from the remote-controlled robot 1 by the communication interface 204 (step S203). In a case where it is determined that the task function acquisition request is not received (NO in step S203), the processor 201 determines whether the measurement information is received from the remote-controlled robot 1 by the communication interface 204 (step S204). In a case where it is determined that the measurement information is not received (NO in step S204), the processor 201 further determines whether the interview content is received from the robot control terminal 3 by the communication interface 204 (step S205). In a case where it is determined that the interview content is not received (NO in step S205), the processor 201 shifts to the processing of step S201 described above. In this way, the processor 201 waits to receive a pre-set content, a schedule acquisition request, a task function acquisition request, measurement information or an interview content.

In a case where it is determined that the pre-set content is received in the step S201 (YES in step S201), the processor 201 stores the received pre-set content in a patrol schedule storage unit 2031 or the task function setting storage unit 2032 of the data memory 203 (step S206). That is, the pre-set contents are described in the patrol schedule table 23 or the task function setting table 24, or the described contents are updated. Next, the processor 201 shifts to the processing in step S201 described above.

In this way, the pre-set work is performed between the robot control terminal 3 and the robot control server 2. For example, a nurse sets a patrol prediction of each remote-controlled robot 1 in the patrol schedule table 23 in the robot control server 2 using the robot control terminal 3, and/or sets the automatic/manual flag to [Automatic] or [Manual] for each patient in the task function setting table 24 for the nursing task to be performed for each patient in each task. For example, as illustrated in FIG. 5, for the patient A, the task function [Room Temperature Measurement] having the task number [001] and the task function [Body Temperature Measurement] having the task number [002] are set to [Automatic], the task function [Blood Pressure Measurement] having the task number [003] and the task function [Interview] having the task number [004] are set to [Manual].

(2) Start of Patrol Task

FIG. 13 is a flowchart illustrating an example of an operation of the remote-controlled robot 1. In a case where the functional configuration of the remote-controlled robot 1 is realized by a computer as illustrated in FIG. 8, a processing program necessary for executing the control processing illustrated in the flowchart is stored in the program memory 102, and the processor 101 executes the program, thereby operating as the remote-controlled robot function unit 10 of the remote-controlled robot 1 as illustrated in FIG. 2. Specifically, after starting the operation, the processor 101 functions as the robot control unit 11 by executing the control program to perform the following processing.

The processor 101 of the remote-controlled robot 1 functions as the patrol management function unit 112 first, and acquires the remote patrol schedule from the robot control server 2 via the access point 4 by the communication interface 104 (step S101). This is, for example, processing for transmitting a schedule acquisition request including a robot number specifying the remote-controlled robot 1 to the patrol prediction management unit 21 of the robot control server 2, receiving the patrol schedule returned from the patrol prediction management unit 21 by the communication interface 104, and storing the patrol schedule in the temporary storage unit 1033 of the data memory 103.

That is, as illustrated in FIG. 12, in a case where it is determined that the schedule acquisition request is received in the step S202 (YES in step S202), the processor 201 of the robot control server 2 returns the patrol schedule of the remote-controlled robot 1 of the request source by the communication interface 204 (step S207). That is, the processor 201 reads out the patrol schedule set for the robot number included in the schedule acquisition request from the patrol schedule table 23 stored in the patrol schedule storage unit 2031, and transmits the patrol schedule to the remote-controlled robot 1. Next, the processor 201 shifts to the processing in step S201 described above.

Returning to FIG. 13, the processor 101 of the remote-controlled robot 1 determines whether to start the patrol (step S102) after acquiring the patrol schedule in the step S101. This determination can be made depending on whether the current date and time counted by the clock 108 has reached the transmission date and start time of the patrol schedule. In a case where it is determined that the patrol is not started (NO in step S102), the processor 101 shifts to the processing of step S101 described above. Although the processing of the step S102 may be simply repeated until the start time of the acquired patrol schedule is reached, since there is a possibility that the patrol schedule is updated during a period from the acquisition of the patrol schedule to the start time, and processor shifts to the processing of the step S101.

In a case where it is determined that the patrol is started (YES in step S102), the processor 101 confirms the patrol order of the patrol schedule stored in the temporary storage unit 1033, and determines whether [Completion] is set in the patrol order to be executed from now (step S103).

When it is determined that [Completion] is not set (NO in step S103), the processor 101 calculates a movement route to a position of a target patient, functions as a drive unit control function unit 152 and controls the drive unit 182 connected to the mechanical unit interface 107 to move the drive unit to the patient (step S104). The processor 101 can calculate a movement route from the current position based on the patrol order indicated by the patrol schedule and the information stored in the facility map storage unit 1031.

In this way, for example, in the case of the remote-controlled robot 1 having a robot number [R01], after starting the operations, the robot refers to the patrol schedule table 23 in the robot control server 2, confirms the patrol start time and patrol order of the host robot, and when the start time comes, the robot starts patrol task by automatic traveling using the drive unit 182, and heads for patrol of patient A in Room 101, which is patrol order 1.

(3) Execution of Task Function

When the robot arrives at the target patient, the processor 101 functions as the task function switching function unit 113, and acquires task function setting contents set for the corresponding patient from the robot control server 2 via the access point 4 by the communication interface 104 (step S105). This is processing for transmitting a task function acquisition request including a patient name specifying the patient to the task function/measurement data management unit 22 of the robot control server 2, receiving the task function setting content returned from the task function/measurement data management unit 22 by the communication interface 104, and storing the content in the temporary storage unit 1033 of the data memory 103.

That is, as illustrated in FIG. 12, in a case where the processor 201 of the robot control server 2 determines that the task function acquisition request is received in the step S203 (YES in step S203), the processor 201 returns the task function setting content of the patient to the remote-controlled robot 1 of the request source by a communication interface 204 (step S208). That is, the processor 201 specifies the task function setting table 24 corresponding to the patient name included in the task function acquisition request from among the task function setting tables 24 of the plurality of patients stored in the task function setting storage unit 2032, reads out the contents, and transmits the contents to the remote-controlled robot 1. Next, the processor 201 shifts to the processing in step S201 described above.

Returning to FIG. 13, if the processor 101 of the remote-controlled robot 1 acquires the task function setting content in the step S105, the processor 101 determines whether all the task functions in the task function setting content stored in the temporary storage unit 1033 are executed, that is, it is determined whether the task for the patient has been completed (step S106). In a case where it is determined that the task is not ended yet (NO in step S106), the processor 101 functions as the manual operation notification function unit 114, and determines whether [Automatic] is set as an automatic/manual flag for the task function to be executed from now (step S107). That is, the processor 101 determines whether the remote-controlled robot 1 has reached the timing of executing switching from autonomous control to manual control.

(3-1) Execution of Automatic Task Function

In a case where it is determined that [Automatic] is set (YES in step S107), the processor 101 functions as the set task function unit set among the plurality of task function units 121, 122, . . . in the function unit storage unit 12, for example, the task function unit 121 for performing a task function [Room Temperature Measurement] of a task number [001] to automatically execute measurement (step S108).

Then, the processor 101 functions as the transmission/reception function unit 131, and transmits measurement information including a patient name, a task function, and a measurement result to the robot control server 2 via the access point 4 by the communication interface 104 (step S109). Next, the processor 101 shifts to the processing in step S106 described above.

As illustrated in FIG. 12, in a case where it is determined that the measurement information is received in the step S204 (YES in step S204), the processor 201 of the robot control server 2 stores the measurement information (step S209). That is, the processor 201 records the measurement result in the corresponding task function of the measurement recording table 25 corresponding to the patient name in the received measurement information from among the measurement recording table 25 of the plurality of patients stored in the measurement record storage unit 2033. Next, the processor 201 shifts to the processing in step S201 described above.

In this manner, for example, the remote-controlled robot 1 having the robot number [R01] arriving at the room 101 refers to the task function setting contents of the task function setting table 24 for the patient A in the robot control server 2, and starts the task function [Room Temperature Measurement] of the task number [001]. Since the task number [001] is described as [Automatic] in the task function setting table 24 for the patient A, the remote-controlled robot 1 having the robot number [R01] moves a room temperature measuring function as the task function unit 121 as it is, measures the room temperature, and transmits the result to the robot control server 2. Then, the robot control server 2 receiving the measurement result from the remote-controlled robot 1 having the robot number [R01] records the result in a measurement recording table 25 for the patient A.

Thereafter, by repeating the processing from the step S106 again, the remote-controlled robot 1 having the robot number [R01] starts the task function [Body Temperature Measurement] of the next task number [002]. Since the task number [002] of the task function setting table 24 for the patient A is also described as [Automatic], the remote-controlled robot 1 having the robot number [R01] also moves a body temperature measuring function as the task function unit 122 to measure the body temperature of the patient A, the result is transmitted to the robot control server 2. Then, the robot control server 2 receiving the measurement result from the remote-controlled robot 1 having the robot number [R01] records the result in the measurement recording table 25 for the patient A.

(3-2) Execution of Manual/Automatic Task Function

In a case where it is determined that [Automatic] is not set in the step S107, that is, [Manual] is set (NO in step S107), the processor 101 functions as the task function switching function unit 113 and determines whether control by the robot control terminal 3 has already been switched (step S110). In a case where it is determined that the control by the robot control terminal 3 is not switched yet (NO in step S110), the processor 101 functions as the call function unit 141 and calls the robot control terminal 3 via the access point 4 by the communication interface 104 (step S111). At this time, the processor 101 calls a specific terminal out of the plurality of robot control terminals 3 based on information for specifying the robot control terminal 3 for manually controlling the remote-controlled robot 1 stored in the control terminal information storage unit 1032. The robot control terminal 3 to be called is not limited to one. Then, the processor 101 determines whether there is a response from the robot control terminal 3 (step S112). In a case where it is determined that there is no response (NO in step S112), the processor 101 continues the processing of the step S111. Thus, the response from the robot control terminal 3 is waited.

As illustrated in FIG. 11, in a case where the processor 301 of the robot control terminal 3 determines that there is a call from the remote-controlled robot 1 in the step S302 (YES in step S302), the processor 301 functions as a call reception function unit 321 and notifies a nurse of the call (step S305). This notification can be made by the monitor 342 and the speaker 345 connected to the input/output interface 305. Then, the processor 301 determines whether a response operation of the nurse is performed (step S306). In a case where it is determined that there is no response operation (NO in step S306), the processor 301 continues the processing of the step S306. Thus, the response operation from the nurse is waited. The response operation is not limited to the operation of the keyboard/mouse 341 connected to the input/output interface 305, but may include a predetermined keyword voice of the nurse acquired by the microphone 344, a predetermined gesture of the nurse acquired by the camera 343, and the like.

In a case where it is determined that the nurse has operated the response (YES in step S306), the processor 301 transmits the response to the remote-controlled robot 1 of the calling source by the communication interface 304 (step S307).

Returning to FIG. 13, the processor 101 of the remote-controlled robot 1 functions as the task function switching function unit 113 to switch to control by the robot control terminal 3 (step S113) in a case where it is determined that there is a response in the step S112 (YES in step S112). Thereafter, the processor 101 transmits the contents of the task to be executed by the manual operation to the robot control terminal 3 via the access point 4 by the communication interface 104 (step S114). Then, the processor 101 determines whether the remote operation content is received from the robot control terminal 3 via the access point 4 by the communication interface 104 (step S115). When it is determined that the remote operation content is not received (NO in step S115), the processor 101 continues the processing of the step S115. Thus, the nurse waits for remote operation.

As illustrated in FIG. 11, the processor 301 of the robot control terminal 3 transmits the response to the remote-controlled robot 1 in step S307 described above, and then notifies the nurse of the task content of the task content transmitted from the remote-controlled robot 1 using the monitor 342 connected to the input/output interface 305 (step S308). Here, the processor 301 determines whether the transmitted task content is remote operation end (step S309).

In a case where the task content is not the remote operation end, the nurse who has confirmed the notification of the task content performs an operation corresponding to the task content. In other words, when the simple arm portion 181, the drive unit 182, and the camera 171 of the remote-controlled robot 1 are remotely operated, the nurse operates the operation device 346. In addition, in the case of making an interview of a patient, the monitor 342, the camera 343, the microphone 344, and the speaker 345 on the robot control terminal 3 side with respect to the camera 171, the monitor 172, the microphone 173 and the speaker 174 of the remote-controlled robot 1 are operated.

Therefore, in a case where it is determined that the remote operation is not ended (NO in step S309), the processor 101 functions as the robot operation function unit 33 or the video/audio communication function unit 142, and receives and acquires the operation contents of the operation device 346 or the monitor 342 connected to the input/output interface 305, the camera 343, the microphone 344, and the speaker 345 (step S310). Then, the processor 301 transmits the acquired operation content to the remote-controlled robot 1 by the communication interface 304 (step S311). Further, the processor 301 determines whether the acquired operation content is an interview (step S312). In a case where it is determined that it is not the interview (NO in step S312), the processor 101 shifts to the processing of step S308 described above.

Returning to FIG. 13, when it is determined that the remote operation content is received from the robot control terminal 3 in the step S115 (YES in step S115), the processor 101 of the remote-controlled robot 1 functions as the robot drive control unit 15 to execute the remote operation content (step S116). That is, the processor 101 drives the simple arm portion 181 and the drive unit 182 connected to the mechanical unit interface 107 according to the received remote control contents. Then, the processor 101 determines whether transmission of the measurement result to the robot control server 2 is necessary as the result of the remote operation (step S117). In a case where it is determined that transmission to the robot control server 2 is necessary (YES in step S117), the processor 101 shifts to the processing of step S109 described above. Then, the processor transmits the measurement result to the robot control server 2 in step S109 described above, and shifts the processing of step S106 described above.

For example, when the remote-controlled robot 1 having the robot number [R01] starts the task function [Blood Pressure Measurement] having the task number [003] by referring to the task function setting contents of the task function setting table 24 for the patient A in the robot control server 2, the task number [003] is described as [Manual] in the task function setting table 24 for the patient A. In this case, the remote-controlled robot 1 switches the control of the function from autonomous control to manual control, and calls a nurse on the robot control terminal 3 side. After responding of the nurse by the robot control terminal 3, the robot notifies the nurse of the arrival of the order of blood pressure measurement as a task content to be performed by manual control, the control right of the remote-controlled robot 1 having the robot number [R01] is transferred to the robot control terminal 3. A nurse operates the simple arm portion 181, the camera 171, the drive unit 182, or the like of the remote-controlled robot 1 having the robot number [R01] by the robot operation function unit 33 of the robot control terminal 3, the blood pressure monitor 6 is mounted on the arm of the patient A to measure the blood pressure. Since the blood pressure monitor 6 has a communication function with the remote-controlled robot 1, the measurement result is transmitted from the remote-controlled robot 1 to the robot control server 2, and the robot control server 2 records the result in the measurement recording table 25 for the patient A.

Further, as illustrated in FIG. 11, the processor 301 of the robot control terminal 3 functions as the patrol prediction/task setting unit 31 in a case where it is determined that the interview is made in step S312 described above (YES in step S312), and receives the input operation of the interview contents by the keyboard/mouse 341 (step S313). Then, the processor 101 transmits the interview contents to the robot control server 2 by the communication interface 304 (step S314). Next, the processor 301 shifts to the processing in step S308 described above.

As illustrated in FIG. 12, in a case where it is determined that the interview content is received in the step S205 (YES in step S205), the processor 201 of the robot control server 2 functions as the task function/measurement data management unit 22, and stores the received interview content in the interview content storage unit 26 of the interview storage unit 2034 (step S210). Next, the processor 201 shifts to the processing in step S201 described above.

For example, when a task to be executed next is a task function [Interview] of a task number [004] in the task function setting table 24 for the patient A, a nurse uses a videophone function of the robot control terminal 3, performs the interview with the patient A via the videophone function unit 14 on the remote-controlled robot 1 side having the robot number [R01], and inputs the interview contents by the keyboard/mouse 341. The input content is transmitted to the robot control server 2, and the robot control server 2 separately saves the input content as an interview record for the patient A.

(4) Movement to Next Room

As described above, the processor 101 of the remote-controlled robot 1 sequentially executes the task contents acquired from the task function setting table 24 by autonomous control or manual control. In a case where it is determined that the task for the patient has ended in step S106 described above in FIG. 13 (YES in step S106), the processor 101 shifts to the processing of step S103 described above. In this case, although not illustrated in particular, the processor 101 transmits the task contents of the end of the remote operation to the robot control terminal 3.

Then, in step S103 described above, the processor 101 confirms the next patrol order from the patrol schedule stored in the temporary storage unit 1033, and if [Completion] is not set in the patrol order to be executed from now, the processor shifts to the processing of step S104 and moves the robot to the next patient.

For example, the remote-controlled robot 1 having the robot number [R01] determines that the task content for the patient A is completed when all the tasks listed in the task function setting table 24 for the patient A are completed, and goes to the patrol task of a patient B in a room 102 which is Patrol Order 2 of the patrol schedule table, the task contents are executed based on the task function setting table 24 for the patient B.

(5) End of Patrol Task

Then, in a case where it is determined that [Completion] is set in step S103 described above (YES in step S103), since it is the fact that the robot for all patients to be patrolled has been patrolled, the processor 101 shifts to the processing of step S101 described above.

Thus, when the patrol order of the patrol schedule table for the remote-controlled robot 1 is ended, the patrol task is ended. In this case, the processor 101 may function as the drive unit control function unit 152 to move the remote-controlled robot 1 to a predetermined standby place by the drive unit 182.

In the first embodiment as described above, the remote-controlled robot 1 autonomously travels to a plurality of task execution places such as a sickroom according to a patrol schedule and executes a plurality of tasks at each task execution place, and includes the task function switching function unit 113 which can be provided by the processor 101. The task function switching function unit 113 operates as a setting acquisition unit and acquires setting of whether to perform an autonomous operation or to perform a manual operation by the operation of an operator such as a nurse from the remote control terminal for each of the plurality of tasks to be executed at each task execution place listed in the task function setting table 24 from the robot control server 2. In addition, the task function switching function unit 113 operates as a first switching unit, and switches between task execution by autonomous operation and task execution by manual operation based on the acquired setting.

Thus, according to the first embodiment, the remote-controlled robot 1 is made to automatically perform the task autonomously performed by the remote-controlled robot 1, and only the task manually performed by an operator such as a nurse can be manually performed from a remote place, and even for a facility where the autonomous control direction task and the manual control direction task are mixed. Thus, the remote-controlled robot 1 can be introduced, and the efficiency of task by the remote-controlled robot 1 can be improved.

In a first embodiment, the remote-controlled robot control system includes the remote-controlled robot 1 which autonomously travels to a plurality of task execution places such as a sickroom according to a patrol schedule and executes a plurality of tasks at each task execution place, the robot control terminal 3 for manually operating the remote-controlled robot 1, and the robot control server 2 to which the remote-controlled robot 1 and the robot control terminal 3 are accessed. The robot control server 2 includes the patrol schedule table 23 as a schedule storage unit for storing a patrol schedule, and the task function setting table 24 as a task storage unit for storing settings of whether to perform autonomous operation or to perform manual operation by the operation of an operator such as a nurse from the robot control terminal 3 for each of a plurality of tasks to be executed at the task execution places relating to each of the plurality of task execution places. In addition, the robot control terminal 3 includes the patrol prediction/task setting unit 31 which can be provided by the processor 101. The patrol prediction/task setting unit 31 operates as a pre-set unit, and performs setting of a patrol schedule and setting of each of a plurality of tasks in the robot control server 2 prior to the operation start of the remote-controlled robot 1. The remote-controlled robot 1 includes the task function switching function unit 113 which can be provided by the processor 101. The task function switching function unit 113 operates as a setting acquisition unit, and acquires setting for each of the patrol schedule and the plurality of task from the robot control server 2. In addition, the task function switching function unit 113 operates as the first switching unit, and switches between task execution by autonomous operation and task execution by manual operation based on the acquired setting.

In this way, the task suitable for automation is autonomously controlled, and also the direct temperature detection of the patient, the measurement of blood pressure, or manual control of a task suitable for manual control such as an interview is set in the task function setting table 24 in advance, the remote-controlled robot 1 performs the task in order based on a state set in the task function setting table 24, calls a remote operator when the order of the manual control task comes, the function is switched to manual operation, and only the task to be manually performed is manually performed by an operator from a remote place. Thus, the remote-controlled robot 1 can be utilized in a facility where autonomous control direction task and manual control direction task coexist.

Second Embodiment

Next, a second embodiment of the present invention will be described. The present embodiment is adapted to cope with a case where a patient to be measured is sleeping during a patrol. The same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment and description thereof will be appropriately omitted.

FIG. 14 is a diagram illustrating an example of a functional configuration of the robot control unit 11 in the remote-controlled robot 1 according to the second embodiment. The robot control unit 11 in the present embodiment includes a sleep determination function unit 115 in addition to the configuration in the first embodiment. The sleep determination function unit 115 has a function of automatically checking the state of the patient to be measured before execution of the task function and determining whether the patient is sleeping or waking up. Whether the user is sleeping can be determined in a complex manner based on an image of the patient imaged by the camera 171, a voice of the patient acquired by the microphone 173, and the like. For example, from the image, information of the patient lying on a bed, the closed eyes, the numerical representation of the vital sign monitor, or the like can be acquired, and a specific pattern seen during sleep such as sleeping breath and snoring can be acquired from the voice.

FIG. 15 is a diagram illustrating an example of the contents of the task function setting table 24 created in the robot control server 2 in the second embodiment in units of patients. In the present embodiment, the task function setting table 24 includes option flags 1 and 2 in addition to items similar to those in the first embodiment. These option flags are set at [*]. The option flag 1 is set to indicate that when the patient has worked, the automatic execution target function can be switched to manual execution. When the option flag 2 is set to indicate that the content of the task can be skipped in a case where the execution of the manual task is not suitable, for example, in a case where the patient is sleeping.

FIG. 16 is a diagram illustrating an example of the contents of the measurement recording table 25 created in the robot control server 2 in the second embodiment in units of patients. In a case where the patient is sleeping, for example, [sleep] indicating that the patient is sleeping is entered in the remark item. For the result of the task which has not been executed, a symbol indicating the result, for example, [-], is entered.

FIG. 17 is a flowchart illustrating an example of an operation of the remote-controlled robot 1 according to the second embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

When moving the robot to the patient in step S104 described above, the processor 101 of the remote-controlled robot 1 functions as the sleep determination function unit 115 to check the state of the patient, confirms whether the patient to be measured is sleeping, and stores the confirmation result in the temporary storage unit 1033 (step S121).

Thereafter, the processor 101 acquires the task function setting contents set for the corresponding patient from the robot control server 2 in step S105 described above, and determines whether the task for the patient has ended in step S106 described above. In a case where the task is not ended yet, it is determined whether [Automatic] is set as an automatic/manual flag in step S107.

Here, in a case where it is determined that [Automatic] is set (YES in step S107), in the present embodiment, the processor 101 functions as the sleep determination function unit 115, it is determined whether the option flag 1 is set to a task function to be executed from now (step S122). In a case where it is determined that the option flag 1 is not set (NO in step S122), the processing is shifted to the processing of the step S108 and the measurement is automatically executed.

On the other hand, in a case where it is determined that the option flag 1 is set (YES in step S122), the processor 101 functions as the sleep determination function unit 115 to determine whether the patient is sleeping (step S123). In this determination, a confirmation result of whether the user is sleeping, which is stored in the temporary storage unit 1033, can be used. In a case where it is determined that the user is sleeping (YES in step S123), the processor 101 shifts to the processing of step S108 described above and automatically executes the measurement.

On the other hand, in a case where it is determined that the patient is not sleeping (NO in step S123), the processor 101 shifts to the processing of step S110 described above. That is, the manual execution is switched even if it is an automatic execution target function.

In addition, in a case where it is determined that [Automatic] is not set in step S107 described above, that is, [Manual] is set (NO in step S107), in the present embodiment, the processor 101 functions as the sleep determination function unit 115 to determine whether the option flag 2 is set to a task function to be executed from now (step S124). Here, in a case where it is determined that the option flag 2 is not set (NO in step S124), the processor shifts to the processing of step S110 described above.

On the other hand, in a case where it is determined that the option flag 2 is set (YES in step S124), the processor 101 determines whether the patient is sleeping (step S125). In this determination, a confirmation result of whether the user is sleeping, which is stored in the temporary storage unit 1033, can be used. In a case where it is determined that the user is not sleeping (NO in step S125), the processor 101 shifts to the processing of step S110 described above.

In addition, in a case where it is determined that the patient is sleeping (YES in step S125), the processor 101 transmits measurement information including a patient name, a task function, and a measurement result to the robot control server 2 via the access point 4 by the communication interface 104 (step S126). In this case, the measurement result indicates that the task has not been executed. Next, the processor 101 shifts to the processing in step S106 described above. In the robot control server 2 receiving such measurement information, [-] is recorded in the corresponding measurement item of the measurement recording table 25 for the corresponding patient, and [sleep] indicating that the patient is sleeping is recorded in the remark item.

As described above, in the second embodiment, a plurality of tasks to be executed at each task execution place, such as a sickroom, are tasks to be executed on a task execution target person, such as a hospitalized patient. For each of a plurality of tasks to be executed at each task execution place, the task function switching function unit 113, as the setting acquisition unit, further acquires a setting indicating whether the task listed as the option flag 2 in the task function setting table 24 can be executed during sleep. In addition, the remote-controlled robot 1 also includes a sleep determination function unit 115 that can be provided by the processor 101. The sleep determination function unit 115 operates as a sleep state detection unit, and detects whether the task execution target person is sleeping. Further, the sleep determination function unit 115 operates as a selection unit, and in a case where it is detected that the task execution target person is sleeping, based on the setting acquired by the task function switching function unit 113, the task execution target person selects and executes a task that can be executed during sleep.

Therefore, according to the second embodiment, the same operation and effect as those of the first embodiment can be achieved, and only such a task that does not cause the task execution target person can be performed, and the sleep of the task execution target person can be prevented from being disturbed.

Further, according to the second embodiment, the sleep determination function unit 115 operates as a measurement information recording unit, and records that the task execution target person was asleep and that which task cannot be performed for this reason in a measurement recording table of the robot control server 2. An operator such as a nurse who has confirmed the table can execute the task which cannot be executed by himself or herself, can incorporate it into the patrol schedule of the remote-controlled robot 1 again, and can execute the task by the remote-controlled robot 1 after the lapse of time.

Third Embodiment

Next, a third embodiment of the present invention will be described. The present embodiment is adapted to cope with the case where a patient to be measured is absent for a reason of a toilet or the like during a patrol. The same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment and description thereof will be appropriately omitted.

FIG. 18 is a block diagram illustrating an example of a functional configuration of the robot control unit 11 in the remote-controlled robot 1 according to the third embodiment. The robot control unit 11 of the present embodiment includes a room occupant determination function unit 116 in addition to the configuration of the first embodiment. The room occupant determination function unit 116 has a function of determining whether a patient to be measured is in a room before execution of the task function, and correcting a patrol schedule in the robot control server 2 in a case where the patient is absent. Whether the patient is in the room or not can be determined based on the image of the inside of the sickroom imaged by the camera 171.

FIG. 19 is a flowchart illustrating an example of an operation of the remote-controlled robot 1 according to the third embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

When the robot moves to the patient in step S104 described above, the processor 101 of the remote-controlled robot 1 functions as the room occupant determination function unit 116, confirms whether the patient to be measured is present in the room, and stores the confirmation result in the temporary storage unit 1033 (step S131).

Then, the processor 101 determines whether the patient is in the room (step S132). In a case where it is determined that the patient is in the room (YES in step S132), the processor 101 shifts to the processing of step S105 described above, and acquires the task function setting content set for the corresponding patient from the robot control server 2.

On the other hand, in a case where it is determined that the patient is not in the room, that is, is absent (NO in step S132), the processor 101 transmits the room occupant information to the robot control server 2 via the access point 4 by the communication interface 104 (step S133). The room occupant information includes information specifying a patient who has been absent, for example, a patient name. Next, the processor 101 shifts to the processing in step S103 described above. That is, the processor 101 skips the task for the patient who is absent, and moves to the patrol task for the next patient.

FIG. 20 is a flowchart illustrating an example of the operation of the robot control server 2 in the third embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

In a case where the processor 201 of the robot control server 2 determines that the interview content is not received in step S205 described above (NO in step S205), the processor 201 further functions as the patrol prediction management unit 21 to determine whether room occupant information is received from the remote-controlled robot 1 by the communication interface 204 (step S221). In a case where it is determined that the room occupant information is not received (NO in step S221), the processor 201 shifts to the processing of step S201 described above.

On the other hand, in a case where it is determined that the room occupant information is received (YES in step S222), the processor 201 updates the patrol schedule table 23 stored in the patrol schedule storage unit 2031 (step S222). Next, the processor 201 shifts to the processing in step S201 described above.

FIG. 21 is a diagram illustrating an example of the contents of the patrol schedule table 23 updated by the update processing of the patrol schedule table 23 in the step S222. For example, it is assumed that room occupant information indicating that the patient A to be measured is absent is received from the remote-controlled robot 1 having the robot number [R01]. In this case, the processor 101 functioning as the patrol prediction management unit 21 rewrites the description of the end of the patrol order of the remote-controlled robot 1 in the patrol schedule table 23, in this case, the description of the items of the patrol order 4 from [Completion] to [101: A] indicating the corresponding patient A. Further, the processor 201 shifts the end of the patrol schedule table 23 by one line, that is, adds items of the patrol order 5, and describes [Completion]. By updating the patrol schedule table 23 in this way, the remote-controlled robot 1 having the robot number [R01] can be made to finally patrol again to the place of the patient who is absent.

As described above, in the third embodiment, a plurality of tasks to be executed at each task execution place such as a sickroom are tasks to be executed to a task execution target person such as a hospitalized patient, the remote-controlled robot 1 further includes the room occupant determination function unit 116 that may be provided by the processor 101. The room occupant determination function unit 116 operates as an absence detection unit and detects whether a task execution target person is absent. Further, the room occupant determination function unit 116 operates as a correction unit, and corrects the patrol schedule of the remote-controlled robot 1 indicated by the patrol schedule table 23 in the robot control server 2 in a case where it is detected that the task execution target person is absent.

Therefore, according to the third embodiment, the same action and effect as those of the first embodiment can be achieved, and in a case where the task execution target person is absent, the patrol schedule is automatically rearranged. Thus, it is possible to execute the task for the task execution target person again thereafter.

Fourth Embodiment

Next, a fourth embodiment of the present invention will be described. In the present embodiment, the nurse is identified and automatic/manual operation can be switched according to the skill level of the nurse. The same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment and description thereof will be appropriately omitted.

FIG. 22 is a block diagram illustrating an example of a functional configuration of the robot control unit 11 in the remote-controlled robot 1 according to the fourth embodiment. The robot control unit 11 of the present embodiment includes an operation nurse confirmation function unit 117 in addition to the configuration of the first embodiment. The operation nurse confirmation function unit 117 has a function of confirming the skill level of a nurse who is trying to remotely operate the remote-controlled robot 1 from the robot control terminal 3.

FIG. 23 is a block diagram illustrating an example of a functional configuration of the robot control server 2 in the fourth embodiment. In the robot control server 2 in the present embodiment, in addition to the configuration of the first embodiment, a nurse skill information table 27 is connected to the task function/measurement data management unit 22. The storage area of the nurse skill information table 27 can be secured in the data memory 203.

In addition, in the present embodiment, it is assumed that the item of the option flag 1 as described in the third embodiment is included in the task function setting table 24.

FIG. 24 is a diagram illustrating an example of a content of the nurse skill information table 27. In the nurse skill information table 27, the skill level of each nurse is described in association with a nurse number identifying each nurse. Here, the nurse skill indicates the operation capability of the remote-controlled robot 1 using the robot control terminal 3, and does not mean the capability of nurse task as a nurse.

FIG. 25 is a flowchart illustrating an example of an operation of the remote-controlled robot 1 according to the fourth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

In a case where it is determined that [Automatic] is set as an automatic/manual flag in step S107 described above (YES in step S107), the processor 101 functions as the operation nurse confirmation function unit 117 and determines whether the option flag 1 is set to a task function to be executed from now (step S141). In a case where it is determined that the option flag 1 is not set (NO in step S141), the process shifts to the processing of step S108 described above and automatically executes the measurement.

On the other hand, in a case where it is determined that the option flag 1 is set (YES in step S141), the processor 101 determines whether the control has been switched to the control by the robot control terminal 3 in step S110 described above, and when it is determined that the control has been switched to the control by the robot control terminal 3 yet, in step S111 described above, the robot control terminal 3 is called through the access point 4 by the communication interface 104.

In the present embodiment, the processor 101 determines whether the nurse number is received from the robot control terminal 3 by the communication interface 104 (step S142). In a case where it is determined that the nurse number is not received (NO in step S142), the processor 101 continues the processing of the step S142. Thus, the robot control terminal 3 waits for the nurse number to be transmitted.

FIG. 26 is a flowchart illustrating an example of an operation of the robot control terminal 3 in the fourth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

After the processor 301 of the robot control terminal 3 notifies the nurse of the call in step S305 described above, in the present embodiment, the processor 301 determines whether there is an input operation of the nurse number as a response operation of the nurse (step S341). In a case where it is determined that there is no input operation of the nurse number (NO in step S341), the processor 301 continues the processing of the step S341. Thus, the terminal waits for input operation of the nurse number by a nurse.

In a case where it is determined that there is the input operation of the nurse number (YES in step S341), the processor 301 transmits the input nurse number to the remote-controlled robot 1 of the calling source by the communication interface 304 (step S342).

Returning to FIG. 25, in a case where it is determined that the nurse number is received in step S142 described above (YES in step S142), the processor 101 of the remote-controlled robot 1 acquires the skill level of the nurse of the nurse number from the robot control server 2 via the access point 4 by the communication interface 104 (step S143). This is processing for transmitting a nurse skill inquiry including a nurse number to the task function/measurement data management unit 22 of the robot control server 2, receiving the nurse skill level returned from the task function/measurement data management unit 22 by the communication interface 104, and storing the level in the temporary storage unit 1033 of the data memory 103.

FIG. 27 is a flowchart illustrating an example of an operation of the robot control server 2 in the fourth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

In a case where it is determined that the interview content is not received in step S205 described above (NO in step S205), the processor 201 of the robot control server 2 further determines whether a nurse skill inquiry is received from the remote-controlled robot 1 by the communication interface 204 (step S241). In a case where it is determined that the nurse skill inquiry is not received (NO in step S241), the processor 201 shifts to the processing of step S201 described above.

On the other hand, in a case where it is determined that the nurse skill inquiry has been received (YES in step S241), the nurse skill level corresponding to a nurse number included in the received nurse skill inquiry is returned by the communication interface 204 (step S242). That is, the processor 201 reads out the skill level of the nurse corresponding to the nurse number included in the nurse skill inquiry from the nurse skill information table 27, and transmits the level to the remote-controlled robot 1. Next, the processor 201 shifts to the processing in step S201 described above.

Returning to FIG. 25, if the nurse skill level is acquired in step S143 described above, the processor 101 of the remote-controlled robot 1 determines whether the skill level of the nurse is [Low Skill] (step S144). In a case where it is determined that the skill level of the nurse is not [Low Skill], that is, [High Skill] (NO in step S144), the processor 101 shifts to the processing of step S113 described above.

As illustrated in FIG. 26, the processor 301 of the robot control terminal 3 transmits the nurse number to the remote-controlled robot 1 in step S342 described above, and then determines whether the task content transmitted from the remote-controlled robot 1 is received (step S343). In a case where it is determined that the task content is not received (NO in step S343), the processor 301 further determines whether the automatic measurement notification transmitted from the remote-controlled robot 1 is received (step S344). In a case where it is determined that the automatic measurement device is not received (NO in step S344), the processor 301 further determines whether a nurse change request transmitted from the remote-controlled robot 1 is received (step S345). In a case where it is determined that the nurse change request is not received (NO in step S345), the processor 301 shifts to the processing of the step S343. Thus, the processor 301 waits for the task contents, the automatic measurement notification, or the nurse change request to be transmitted from the remote-controlled robot 1.

In a case where it is determined that the automatic measurement device is received in step S343 described above (YES in step S344), the processor 301 shifts to the processing of step S308 described above. Thus, even in the automatic execution target function, if the skill level of the nurse is [High Skill], the automatic execution is switched to manual execution.

Returning to FIG. 25, in a case where the processor 101 of the remote-controlled robot 1 determines that the skill level of the nurse is [Low Skill] in step S144 described above (YES in step S144), the processor 101 further determines whether the option flag 1 is set to a task function to be executed from now (step S145). Here, in a case where it is determined that the option flag 1 is set (YES in step S145), since the task is the task content that can be automatically executed, the processor 101 transmits an automatic measurement notification to the robot control terminal 3 via the access point 4 by the communication interface 104 (step S146). The automatic measurement notification indicates that the measurement which is the content of the function is automatically executed, and requests another nurse to change the nurse because the nurse's skill level is low. Next, the processor 101 shifts to the processing in step S108 described above and automatically executes the measurement.

As illustrated in FIG. 26, in a case where it is determined that the automatic measurement notification is received in step S344 described above (YES in step S344), the processor 301 of the robot control terminal 3 notifies a nurse of the reception of the automatic measurement notification by a monitor connected to the input/output interface 305 (step S346). That is, the remote-controlled robot 1 automatically executing the measurement and the nurse change request are displayed on the monitor 342. Next, the processor 301 shifts to the processing in step S341 described above and waits for changing the nurse.

Returning to FIG. 25, in a case where it is determined that the option flag 1 is not set in step S145 described above (NO in step S145), the processor 101 of the remote-controlled robot 1 transmits the nurse change request to the robot control terminal 3 via the access point 4 by the communication interface 104 (step S147). That is, since the fact that the option flag 1 is not set means that the task is determined later in the task requiring manual execution in step S107 described above, the processor 101 requests the robot control terminal 3 to change to a nurse having a high level of operation skill. Next, the processor 101 shifts to the processing in step S142 described above.

As illustrated in FIG. 26, in a case where it is determined that the nurse change request is received in step S345 described above (YES in step S345), the processor 301 of the robot control terminal 3 notifies the nurse of the reception of the nurse change request by a monitor connected to the input/output interface 305 (step S347). That is, the nurse change request is displayed on the monitor 342. Next, the processor 301 shifts to the processing in step S341 described above and waits for a change of nurse.

For example, in a case where the nurse having a nurse number [N002] as illustrated in FIG. 24 responds to the call notification from the remote-controlled robot 1, the nurse is a nurse with [Low Skill]. Here, when the option flag 1 is set as in the task [Body Temperature Measurement] of the task number [002] as illustrated in FIG. 15, it is possible to switch to the measurement by manual operation of the nurse, but since the level of the operation skill of the responding nurse is low, automatic measurement is performed. Then, a change to a nurse whose operation skill is high level is requested.

On the other hand, in a case where the nurse number [N001], which is [High Skill], responds to the call notification from the remote-controlled robot 1 as illustrated in FIG. 24, the measurement is switched to the measurement by manual operation of the nurse.

Here, an example of the case of two stages of high and low as the nurse skill level has been explained, but it is of course possible to have multiple stages. In this case, automatic measurement/manual measurement can be set in stages.

As described above, in the fourth embodiment, a plurality of tasks include tasks that can be operated by both autonomous operations and manual operations such as body temperature measurement, and the remote-controlled robot 1 includes the operation nurse confirmation function unit 117, which can be provided by the processor 101. The operation nurse confirmation function unit 117 operates as a level acquisition unit, and acquires an operation skill level of an operator of the remote-controlled robot 1, such as a nurse described in the nurse skill information table 27, from the robot control server 2. In addition, the operation nurse confirmation function unit 117 operates as a second switching unit, and for a task capable of both autonomous operation and manual operation, switches between the task execution by the autonomous operation and the task execution by the manual operation according to the acquired operation skill level.

Therefore, according to the fourth embodiment, the same operation and effect as those of the first embodiment can be achieved, and switching can be performed according to the operation skill level of an operator such as a nurse.

Fifth Embodiment

Next, a fifth embodiment of the present invention will be described. The present embodiment is adapted to cope with the case where an automatic analysis function of the interview contents is added. The same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment and description thereof will be appropriately omitted.

FIG. 28 is a block diagram illustrating the functional configuration of the videophone function unit 14 of the remote-controlled robot 1 according to the fifth embodiment. In addition to the configuration of the first embodiment, the videophone function unit 14 of the present embodiment includes the interview analysis function unit 143. The interview analysis function unit 143 has a function of automatically recording and automatically analyzing the conversation contents between the patient and the nurse during the interview.

FIG. 29 is a flowchart illustrating an example of an operation of the remote-controlled robot 1 according to the fifth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

In a case where it is determined that the remote operation content is received from the robot control terminal 3 in step S115 described above (YES in step S115), the processor 101 of the remote-controlled robot 1 executes the remote operation content in step S116 described above. Here, the processor 101 functions as the interview analysis function unit 143 to determine whether the remote operation content includes an interview, that is, conversation (step S151). In a case where it is determined that the conversation is not included (NO in step S151), the processor 101 shifts to processing of step S154 to be described later.

On the other hand, in a case where it is determined that the conversation is included (YES in step S151), the processor 101 records the conversation content in the temporary storage unit 1033 (step S152). Then, the processor 101 analyzes the recorded conversation contents and stores the analysis result in the temporary storage unit 1033 (step S153).

Thereafter, the processor 101 determines whether the conversation analysis result is stored in the temporary storage unit 1033 (step S154). In a case where it is determined that the conversation analysis result is not stored (NO in step S154), the processor 101 shifts to the processing of the step S109 and transmits measurement information such as blood pressure to the robot control server 2.

On the other hand, when it is determined that the conversation analysis result is stored (YES in step S154), the processor 101 transmits the stored conversation analysis result to the robot control server 2 via the access point 4 by the communication interface 104 (step S155). Here, the processor 101 is assumed to include information for specifying a patient such as a patient name in the conversation analysis result to be transmitted. Next, the processor 101 shifts to the processing in step S106 described above.

FIG. 30 is a flowchart illustrating an example of an operation of the robot control server 2 in the fifth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

In a case where it is determined that the interview content is not received from the robot control terminal 3 in the step S205 (NO in step S205), the processor 201 of the robot control server 2 further determines whether the conversation analysis content is received from the remote-controlled robot 1 by the communication interface 204 (step S251). In a case where it is determined that the conversation analysis content is not received (NO in step S251), the processor 201 shifts to the processing of step S201 described above.

On the other hand, in a case where it is determined that the conversation analysis content has been received (YES in step S251), the received conversation analysis content is stored in the interview content storage unit 26 of the interview storage unit 2034 (step S252). At this time, the processor 201 specifies the measurement recording table 25 for the patient according to the patient name or the like included in the conversation analysis content, and describes “YES” in the item of the interview. Next, the processor 201 shifts to the processing in step S201 described above.

As described above, in the fifth embodiment, a plurality of tasks to be executed at each task execution place such as a sickroom include a task such as an interview requiring conversation between a task execution target person such as a hospitalized patient and an operator such as a nurse, and the remote-controlled robot 1 further includes the video/audio communication function unit 142 and the interview analysis function unit 143 that can be provided by the processor 101. The video/audio communication function unit 142 operates as a videophone unit, and when executing a task requiring conversation, the video/audio communication function unit 142 performs video/audio communication with the robot control terminal 3 using the camera 171, the monitor 172, the microphone 173, and the speaker 174. The interview analysis function unit 143 operates as a conversation recording unit, and records a conversation exchanged between the task execution target person and the operator by video/audio communication. In addition, the interview analysis function unit 143 operates as an analysis unit to analyze the contents of the recorded conversation. Further, the interview analysis function unit 143 operates as a saving unit, and saves the analysis result in the interview content storage unit 26 of the robot control server 2.

Therefore, according to the fifth embodiment, the same action and effect as those of the first embodiment can be obtained, and the contents of the interview can be automatically generated and stored from the conversation between the task execution target person and the operator, so that the operator can save the labor of inputting the contents of the interview.

Sixth Embodiment

Next, a sixth embodiment of the present invention will be described. In the present embodiment, when the automatic task of the remote-controlled robot 1 is started, the nurse side is notified of the task execution state, and the nurse side can monitor the task of the remote-controlled robot 1 during the autonomous operation. The same configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment and description thereof will be appropriately omitted.

FIG. 31 is a block diagram illustrating an example of a functional configuration of the videophone function unit 32 of the robot control terminal 3 in the sixth embodiment. In addition to the configuration of the first embodiment, the videophone function unit 32 of the present embodiment includes a manual operation request function unit 323. The manual operation request function unit 323 has a function of monitoring a situation during autonomous operation of the remote-controlled robot 1 by a nurse side. That is, the video acquired by the camera 171 of the remote-controlled robot 1 is displayed on the monitor 342, and the voice acquired by the microphone 173 of the remote-controlled robot 1 is reproduced by the speaker 345.

FIG. 32 is a flowchart illustrating an example of an operation of the remote-controlled robot 1 according to the sixth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

When the robot moves to the patient in step S104 described above, the processor 101 of the remote-controlled robot 1 functions as the call function unit 141, and transmits an arrival notification to the robot control terminal 3 via the access point 4 by the communication interface 104 (step S161). Then, the processor 101 determines whether a start instruction is received from the robot control terminal 3 by the communication interface 104 (step S162). In a case where it is determined that the start instruction is not received (NO in step S162), the processor 101 continues the processing of the step S162. Thus, the processor 101 waits for the start instruction to be transmitted from the robot control terminal 3.

FIG. 33 is a flowchart illustrating an example of an operation of the robot control terminal 3 in the sixth embodiment. In the same drawing, parts similar to those of the first embodiment are omitted.

In a case where the processor 301 of the robot control terminal 3 determines that there is no pre-set operation in step S301 described above (NO in step S301), the processor 301 functions as the call reception function unit 321 in the present embodiment, and determines whether there is an arrival notification from the remote-controlled robot 1 via the communication interface 304 (step S361). In a case where it is determined that there is no arrival notification (NO in step S361), the processor 301 shifts to the processing of step S301 described above. Thus, the processor 301 waits for a pre-set operation or an arrival notification.

In a case where it is determined that there is the arrival notification in step S361 described above (YES in step S361), the processor 301 notifies the nurse that the remote-controlled robot 1 arrives at the patient by the monitor 342 and/or the speaker 345 connected to the input/output interface 305 (step S362). Thereafter, the processor 301 functions as the manual operation request function unit 323, and determines whether there is a start instruction input from a nurse by the keyboard/mouse 341 connected to the input/output interface 305 (step S363). In a case where it is determined that there is no start instruction input (NO in step S363), the processor
