Abstract: The application of the virtual prototype technology can create the virtual model and make the dynamic simulation for a mobile robot mechanism.An improving 3D mechanism model of the mobile robot is created using SOLIDWORKS and the modularization design method is adopted.The dynamic simulation for two levels shock absorber in the robot mechanism is made using ADAMS and the effect compares with the simulation effect of one level shock absorber before improving.The result shows that two levels shock absorber can solve the question of the joint between four wheels of the mobile robot and the ground at any moment more effectively than one level shock absorber and has better shock absorption effect，therefore makes the robot’s movement capability and adaptability on the environment more optimistic.
