The main work of this paper: Firstly, Basing on the summarization and analysis of the walking mechanism, Parallel drive five-bar mechanism is applied for walking mechanism. And then the characteristic of the trail and positive kinematics as well as reverse kinematics are discussed. Secondly, the model of walking mechanism is established according to Parallel drive five-bar mechanism, and then a figure planning is designed for the foot-end trail. The characteristics of the parallel drive are emphasized to research in this paragraph by the method of insert value. At last, the simulation is performed in the ADAMS to compare the real result to the theoretical value. Thirdly, a sealed structure of a Quadruped Walking Robot is designed and established. The whole control system, including motor, sensor and control circuit, is sealed in the robot. Walking is derived in the way of the shaft driving and the dynamic torque sensor is used to the surrounding conditions of the robot's foot-end to be the foundation of the robot's control. At last, the applying principle of the dynamic torque sensor is researched in detail basing on the traditional sensor of the walking robot. Moreover, the principle is divided into several sorts to discuss. Finally, simulation and verification of the monitor principle are come through in the Mechanism of the Pro/Engineer.
