Atlas is a bipedal humanoid robot primarily developed by the American robotics company Boston Dynamics, with funding and oversight from the United States Defense Advanced Research Projects Agency (DARPA). The 1.8-meter (6 ft) robot is designed for a variety of search and rescue tasks, and was unveiled to the public on July 11, 2013.
On February 23, 2016, Boston Dynamics released video of a new version Atlas robot on YouTube. The new version of Atlas is designed to operate both outdoors and inside buildings. It is specialized for mobile manipulation and is very adept at walking over a wide range of terrain, including snow. It is electrically powered and hydraulically actuated. It uses sensors in its body and legs to balance, and it uses LIDAR and stereo sensors in its head to avoid obstacles, assess the terrain, help with navigation, and manipulate objects, even when the objects are being moved. This version of Atlas is about 175 cm (5 ft 9 in) tall (about a head shorter than the DRC Atlas) and weighs 180 lb (82 kg) lbs.
