Boston Dynamics has revealed Atlas, the newest iteration of their autonomous humanoid robot. It can let itself outdoors, walk on snowy ground, pick up boxes, and right itself after being pushed by a human. (Link to video). They say:
"It is specialized for mobile manipulation. It is electrically powered and hydraulically actuated. It uses sensors in its body and legs to balance and LIDAR [laser surveying technology] and stereo sensors in its head to avoid obstacles, assess the terrain, help with navigation and manipulate objects. This version of Atlas is about 5' 9" tall (about a head shorter than the DRC Atlas) and weighs 180 lbs."
