Researches on a wall-climbing robot based on electromagnetic adsorption

Wall-climbing robots have wide application in industry and other fields. At present, the technical bottleneck of the wall-climbing robots based on magnetic adsorption is that the magnetic force is not only the adsorption force but also the moving resistance force. The bigger the adsorption force is, the bigger the moving resistance force is. In order to solve this problem, a unique wall-climbing robot based on electromagnetic adsorption is proposed in this paper. Electromagnets fixed in the synchronous belts get into or out of work in turn to realize the unity of adsorption and mobility. An embedded Linux system is constructed to transport videos from the robot to the handheld terminal in real time. A MCS-51 based controller is designed to perform robot control. A prototype robot is manufactured and tested. Experiments show the video delay is less 0.45s and the remote-control distance is beyond 80m.
