Using virtual Prototyping Technology designs mechanism system. We utilize the kinematics and dynamics simulation function of virtual prototype software UG to get the kinematics and dynamics characteristic of the planar four-DOF assembly robot arm. The simulation results of the analysis can help us modify the material of part and improve the structure design. Applying virtual Prototyping Technology is important for improving the quality of product and decrease the case of product. We first build the model of the planar four-DOF assembly robot; then establish the kinematics and dynamics equation of the planar four-DOF assembly robot arm, and do some theoretical research on the kinematics and dynamics characteristics of the robot arm. For the two-bar robot arm, we focus merely the whole kinetic energy at horizontal condition, and neglect the change of potential energy due to the bending deflection of the robot arm. In the simulation of the kinematics and dynamics of robot arm, we use UG to get the displacement, speed, acceleration, force, torque, kinetic energy of each link and the whole kinetic energy of robot arm, etc. Such information will support the design of robot arm.
