Robotic Technologies for In-Space Assembly Operations

On-orbit robotic assembly is a key technology that can increase the size and reduce costs of construction of large structures in space. This document provides an overview of existing or emerging robotic technologies for space-born assembly, including also the development of standard interfaces for connectivity that combine mechanical connections with electronic and power signals. Technologies that can enable on-orbit assembly demonstrations in the near future are currently under development at the Institute of Robotics and Mechatronics in the German Aerospace Center - DLR, as showcased in a setup for autonomous assembly of structures made out of standard aluminium profiles.
