Abstract

Modular Large Aperture Space Telescopes (LAST) hold the key to future astronomical missions in search of the origin of the cosmos. Robotics and Autonomous Systems technology would be required to meet the challenges associated with the assembly of such high value infrastructure in orbit. In this paper an End-Over-End walking robot is selected to assemble a 25m LAST. The dynamical model, control architecture and gait pattern of the E-Walker are discussed. The key mission requirements are stated along with the strategies for scheduling the assembly process. A mission concept of operations (ConOps) is proposed for assembling the 25m LAST. Simulation results show the precise trajectory tracking of the EWalker for the chosen mission scenario.
