Module Overview

This module covers the techniques and challenges involved in space robotic missions for on-orbit servicing and planetary exploration. A detailed mathematical analysis of the kinematics and dynamics of robotic arms will be provided. Robotic arm control design and traction control will be taught. Various aspects and techniques of improving autonomy of space robotic systems will be introduced, including sensing, perception, localization, mapping, autonomous planning and navigation.

Prerequisites/Co-requisites

Completion of the progress requirements of Level HE3. To study this subject successfully requires an interest in mechatronics and robotic space exploration. A good mathematical background  and an adequate grasp of control engineering woudl be very helpful. Programming skill in either Matlab or C language is required to successfully complete the coding assignments.
Module Aims

To introduce the student to the key principles and techniques of spacecraft robotics.
Learning Outcomes
Upon sucessful completion of the module students should be able to: 
  • Describe the principles and techniques involved in the mechanical and electrical design of space robotic systems. 
  • analyse the kinematics and dynamics of robot manipulators and design control systems for manipulators.
  • describe the key aspects and techniques involved in autonomy of space robots.
  • demonstrate the implementation of traction control systems for planetary rovers.
  • discuss various space robotic missions and describe the inevitable role played by robots for space exploration.
