Robonaut R2 media day in building 9NW

JSC2010-E-112701 (4 Aug. 2010) --- NASA astronaut Michael Barratt, STS-133 mission specialist, shakes hands with Robonaut 2 (R2) during media day in the Space Vehicle Mock-up Facility at NASA's Johnson Space Center. R2 is the first humanoid robot to travel to space and the first U.S.-built robot to visit the International Space Station. R2 will stay on the space station indefinitely to allow engineers on the ground to learn more about how humanoid robots fare in microgravity. Ron Diftler, NASA Robonaut project manager, is at left.
