This paper presents the synthesis procedure of an input profile for a motion control system to simultaneously reduce sinkage and vibration in a planetary rover. The sinkage of the rover changes depending on the degree of a contact force against loose soils in surface of a planet. Through the experiments using the lunar regolith simulant, it is confirmed that the sinkage is largely concerned with acceleration and deceleration in a driving mechanism. Hence, we proposes the method to suppress the sinkage by appropriately designing the acceleration profile with an asymmetric shape. Moreover, the vibration due to flexibility of the wheel is induced by self-motion and we verify the vibration reduction using the command shaping method through the experiment. Consequently, this paper presents the easy design procedure of the acceleration profile and the valuable experimental results.
