Abstract
In this paper, a crawler-type wall-climbing robot with negative pressure adsorption is designed. The dynamic model of the robot is established based on the method of discretizing the force load of the track shoe. The correctness of the kinematic model and dynamic model is proved by comparing two different ways of virtual prototype simulation and prototype experiment. According to the simulation results of the dynamic model and virtual prototype, the influence of design parameters on the motion performance of the wall-climbing robot is analyzed. The smaller the speed difference between the two tracks of the robot, the longer the gauge between the two tracks, and the greater the inclination of the adsorption wall, the larger the turning radius of the robot will be. The research content based on this paper can provide a new design optimization method and theoretical basis for improving crawler wall-climbing robots and crawler vehicles.
