Atlas is based on Boston Dynamics' earlier PETMAN humanoid robot, and is illuminated with blue LEDs. Atlas is equipped with two vision systems – a laser rangefinder and stereo cameras, both controlled by an off-board computer – and has hands with fine motor skill capabilities. Its limbs possess a total of 28 degrees of freedom. Atlas can navigate rough terrain and climb independently using its arms and legs, although the 2013 prototype version was tethered to an outside power supply.
