Robonaut 2, NASA's Humanoid Space Robot, Will Get Legs Soon - Video

NASA's humanoid robot astronaut is getting its space legs. 

The space agency is building lower limbs for Robonaut 2, a robot designed to eventually help astronauts by taking over some of their duties on the International Space Station. 

R2, as NASA calls it, is currently legless with its torso attached to a support post in the orbiting outpost. 

The new NASA video of Robonaut 2 with legs shows the strange ways the robotic limbs can move.
