US Marines have recently revealed field tests of an LS3 (Legged Squad Support System) at the Kahuku Training Area in Oahu, Hawaii.
Developed by Boston Dynamics, LS3 is a rough-terrain robot designed to carry the load of military personnel on a range of surfaces.
According to the company, each LS3 carries up to 400lbs of equipment and enough fuel for a 20-mile mission lasting 24 hours.
They add that LS3 automatically follows its leader using computer vision, so it does not need a dedicated driver. It also travels to designated locations using terrain sensing and GPS. LS3, which is funded by DARPA and the US Marine Corps, began a two-year field-testing phase in 2012.
