From the mechanics analysis, the relationships between the configure parameters (such as the wheel parameters and the position of mass center) and the mobility performane indexes (such as the wheel sinkage, motion resistance and drawbar pull) are obtained. The design principles of the wheel parameters, position of mass center and the wheel space are given. It is demonstrated that the mass center is crucial to the mobility performance of the lunar rover.
