LS3 (Legged Squad Support System) is a four-legged robot developed by Boston Dynamics. LS3 was designed particularly for use in the military; they have the ability to go anywhere a solider goes on foot and can carry up to 400 pounds worth of gear on their back. It uses computer vision or GPS to either follow someone or get to a predesignated location. LS3 was built by a team of scientists and engineers from Boston Dynamics, Carnegie Mellon, AII Corporation, Bell Helicopter, Woodward HRT, and the Jet Propulsion Laboratory. The development of LS3 was funded by DARPA and the US Marine Corps.
