NASA's loveable robo-torso was the first humanoid (upper body) in space. Created by the Dextrous Robotics Laboratory at Johnson Space Center, Robonaut has been 15 years in the making and was finally sent up to the International Space Station in 2011. As of this writing, R2 waits patiently for his climbing legs to be delivered by the SpaceX resupply ship. This teleoperated robotic astronaut will work alongside crewmembers doing maintenance tasks and assisting on space walks.
