This is amazing stuff.This version of Atlas was designed to operate outdoors and inside buildings. It is electrically powered and hydraulically actuated. It uses sensors in its body and legs to balance. LIDAR and stereo sensors in the head are used to avoid obstacles, assess the terrain and help with navigation. This version of Atlas is about 5'9" tall (about a head shorter than the DRC Atlas) and weighs in at 180 lbs.
