    The next ten years will see an unprecedented increase in the number of spacecraft deployed in Earth orbit and the number of commercial ventures operating space assets. The large increase in the number of spacecraft and the large increase in the commercial value of space will lead to renewed interest in robotic on-orbit servicing (OOS) and active debris removal (ADR). The lecture will provide a brief overview over the history of crewed and robotic OOS and discuss the missions planned for the near future. It will then proceed to identify the critical enabling technologies for a future, operational OOS and ADR infrastructure, discuss the technical challenges and present promising concepts and demonstrated technologies that can make routine OOS and ADR a possibility. The focus will be on robotics technologies and spacecraft guidance, navigation and control systems

    A robot swarm assisting a human fire-fighter

    Emergencies in industrial warehouses are a major concern for fire-fighters. The large dimensions, together with the development of dense smoke that drastically reduces visibility, represent major challenges. The GUARDIANS robot swarm is designed to assist fire-fighters in searching a large warehouse. In this paper we discuss the technology developed for a swarm of robots assisting fire-fighters. We explain the swarming algorithms that provide the functionality by which the robots react to and follow humans while no communication is required. Next we discuss the wireless communication system, which is a so-called mobile ad-hoc network. The communication network provides also the means to locate the robots and humans. Thus, the robot swarm is able to provide guidance information to the humans. Together with the fire-fighters we explored how the robot swarm should feed information back to the human fire-fighter. We have designed and experimented with interfaces for presenting swarm-based information to human beings
