Abstract:Wall adsorption is one of the basic functions of a wall climbing robot, and its adsorption degree directly affects the stability and moving speed of the robot. Therefore, a wall climbing robot adsorption control system based on DSP technology is designed. Select the sensor device of the wall climbing robot, add DSP digital signal processor, and design the adsorption controller of the wall climbing robot. Under the support of the hardware structure, the corresponding mathematical model is constructed according to the composition structure and working principle of the wall climbing robot. In this model, DSP technology is used to calculate the adsorption force of the wall climbing robot. Through the force analysis results of the wall climbing robot in the wall environment, the safe adsorption conditions of the wall climbing robot are determined. The adsorption controller is used as the actuator to realize the adsorption control of the wall climbing robot. The negative pressure wall climbing robot is selected as the test prototype. The system test shows that the control error of the wall climbing robot's adsorption force is reduced by 2.04N and the overturning risk coefficient is reduced by 0.29 compared with the two comparison systems under the three wall environments of ceramic tile, wood board and glass.
