Summary. Space robotics will become a key technology for the exploration of outer space and the operation and maintenance of space stations, satellites and other plat-forms, saving costs and relieving man from dangerous tasks. But we do not have to wait until robots are really autonomous or intelligent, since by modern tele-operation and tele-presence we are able to remotely control robot systems from the ground in the sense of \prolonging man's arm into space". Humans, with their several hun-dred thousand years of evolution, will not adapt themselves to the hostile space environment, whilst robots, which have only been developed for just over 40 years, can be much more easily adapted to such an environment. As presented within this work few pioneering telerobotic experiments like ROTEX, the rst remotely con-trolled space robot system, ETS-VII, the rst free-
oating space robot experiment, or ROKVISS, Germany's recent advanced space robot experiment on the Interna-tional Space Station, have been proposed and conducted on the way towards a space robot assistant system for the usage as an articial astronaut to perform On-Orbit Servicing (OOS) tasks.
