In the space community, any unmanned spacecraft can be called a robotic spacecraft. However, Space Robots are considered to be more capable devices that can facilitate manipulation, assembling, or servicing functions in orbit as assistants to astronauts, or to extend the areas and abilities of exploration on remote planets as surrogates for human explorers.
In this chapter, a concise digest of the historical overview and technical advances of two distinct types of space robotic systems, orbital robots and surface robots, is provided. In particular, Sect. 55.1 describes orbital robots, and Sect. 55.2 describes surface robots. In Sect. 55.3, the mathematical modeling of the dynamics and control using reference equations are discussed. Finally, advanced topics for future space exploration missions are addressed in Sect. 55.4.
DLR predictive simulation compensating 6-second round-trip delay

This brief video shows results of the ROTEX experiment on the fully automatic grasping of a small free-floating cube with flattened edges by the ground computers which evaluated the stereo images from the robot gripper, estimated the motion, predicted it for the 6 s communication round-trip delay, and sent up the commands for grasping. In the view are the results of predictive simulation (right-hand side) and the delayed true-camera measurements (left-hand side).
