NASA is developing a bunch of robots it wants to send to space. Some are humanoid like the RoboSimian and Robonaut 2. But other bots like the Ice Worm, Astrobee, and LEMUR are more abstract. Of course, there's also the Mars 2020 Rover. Which will be bringing along several smaller robots. NASA tests these robots in extreme conditions on Earth in order to prepare them for other planets and moons.
