We are going to use even more sophisticated robots to explore space and objects on other planets. This video from NASA shows a bunch of space robots that can complete a variety of tasks. This rock-climbing robot with grippers to attach to rocks and climb them.
As it is explained in the video, speed is not always a priority when it comes to designing space robots. These robots will be used to explore cliff faces, cave ceilings, and the surfaces of asteroids and comets.
