System description

The robot "SpaceClimber" project will prove that legged systems present a very suitable solution to future extraterrestrial missions in unstructured, uneven terrain, in particular in crater and crevices in the rock. The robot system to be developed will be able to safely control up to 80 % non-uniform grades. Local autonomous navigation will be possible due to special sensor technology and new software algorithms for slope navigation.

Thus, in the field of planetary mobility, a technology will be developed which will make future crater and canyon exploration possible. Special emphasis is given to robustness, energy efficiency, redundancy, and autonomy of the robot.

The most important component to reach these goals are the actuators for the locomotor system. Hence, intelligent, lightweight, powerful and energy efficient joints have been developed for the system. As high stability in steep terrain is of utmost importance, the development and realization of novel feet concepts play an important role in the SpaceClimber Project.
