Abstract
:
This paper presents the lessons learned from the design and control of the exploration rover Sherpa (c.f. Figure 1(a)). The mechanical design of the rover as well as its locomotion control are addressed. Achievements and drawbacks from the initial design of Sherpa are outlined and lead to a discussion of the revised design of the active suspension. A revised locomotion control software is currently under development and part of the discussion in the full paper. Sherpa makes use of an active suspension system to enhance locomotion capabilities [3]. In literature various rover systems using an active suspension approach are present. (Tri-)Athlete [4], Scarab [1], MTR [2] are only a few examples of wheeled-robots with an active suspension system.
