Analysis of gait control of wall-climbing caterpillar robot

In order to verify the benefit of four links kinematical method, the mathematical model of four links kinematics is established. The kinematical parameters of passive joints can be calculated according to the rotation of active joint. Then the wall-climbing robot can climb the vertical wall through the coordinated rotation of active joint and passive joints. To testify the feasibility of the four links kinematical method, a wall-climbing caterpillar robot based on vibrating suction method is developed. An experiment of wall-climbing confirms the kinematical method mentioned above. The result shows that the four links kinematical method is simple and reliable although some errors exist. At last, the conclusions and future works are present.
