Robots are going to play a huge role in space exploration. The Robonaut is a humanoid robot that can perform regular and repetitive tasks inside and outside the space station. It has climbing legs that allow it to perform in zero gravity. Robonaut 2 can anchor one of its legs to the station while assisting astronauts with two hands.
R2 has a fully extended leg span of 9 feet, so it can move around the space station. Each leg has 7 joints and an end effector to get things done. These videos show you what Robonaut is capable of.
