Mechanism parameter fuzzy optimal design of lunar rover

In order to complete the exploration task, the lunar rover not only needs good mobility, and also requires compact structure, small volume, and light quality. Taking the wheel-legged mechanism of lunar rover as research object, this paper established three wheel-legged mechanism design constraint functions, considering the fluctuation of rover body, obstacle-climbing capability and anti-interference ability. On this basis, taking the minimum volume of the wheel-legged mechanism as general optimize goal. By adopting optimal level set method, the wheel-legged mechanism parameter fuzzy optimization was done, and the general function values were achieved by MATLAB optimization toolbox. The optimization results show that the general volume of wheel-legged mechanism is reduced, thus contribute to optimizing the whole rover.
