VIDEO: DARPA robotic horse carries gear for military squads

Defense Advanced Research Projects Agency (DARPA) has developed a robotic horse that will alleviate the physical strain and fatigue soldiers experience when they have to carry over 100 pounds of gear. The highly mobile and semi-autonomous four-legged robot is called Legged Squad Support System (LS3) and can perceive obstacles to adjust its path. The LS3 was designed for squad support and thus has a significantly higher carrying capacity than DARPA's earlier mobility technology, BigDog.
