Introduced the process of Layout in the Pro/E, explained how to use the Layout to drive the designing change with the mechanism of RSSR, and use the simulation module together in the Pro/E, in the first phase of designing, using the method can prove the plan of designing quickly, and improve the designing efficiency.

A type of spatial closed chains of RSTR was applied in the walking robot design. By kinematical analysis and simulation with Pro/E, the track of the walking robot was given. Compared with the track of a planar crank mechanism, the conclusion is drawn: the walking robot presented here, has stability of barycenter and even velocity; and it has simpler control due to using single degree of freedom and closed chain mechanism.
