In-Space Assembly Operations

Kurzfassung

In the last two decades, robotized On-Orbit Servicing (OOS) missions are increasingly gaining importance. OOS addresses the maintenance of space systems in orbit, including repairing and refueling, using technologies that can be extended to construct large space structures. On-orbit robotic assembly can potentially reduce costs and allow larger sizes for construction of structures directly in space. This chapter provides an overview of existing or emerging robotic technologies for space-born assembly, including missions that include robotic arms, and development of standard interfaces for connectivity that combine mechanical connections with electronic and power signals. Given the high delays in communication and the repetitive and demanding tasks required, teleoperating a robotic assembly system from Earth is not straightforward. Therefore, the robotic assembly system should behave autonomously. This kind of autonomous assembly system has been explored for ground applications, as illustrated with an example developed at the Institute of Robotics and Mechatronics in the German Aerospace Center (DLR).
