The first humanoid robot in space came to life today. Its name is Robonaut 2, nickname is R2 (get it?). He's designed to be an astronaut's helper, and he is currently living up in the International Space Station.
Today ground controllers at NASA's Johnson Space Center sent the command to power R2 up for the first time. He didn't move around or anything. NASA takes things pretty slow, so he doesn't get to move around for at least another week. But somehow, he's still able to tweet.
Hmmm.... robots mixing with humans on a spaceship. What could go wrong?
