Design of a Vacuum Adsorption Wall Climbing Robot

Abstract

In this paper, a new type of wall climbing robot with multi vacuum suckers is developed. The robot structure and working principle are introduced in detail. The analysis of safe adsorption force of the wall climbing robot. The mechanical model of the suckers is established. The adsorption force of the suckers is determined based on the experiments. The robot prototype is made. And a large number of experiments are carried out to verify the feasibility of the wall climbing robot. The experiments include robot wall adaptability test and maximum load capacity test, and all. The experiments result show that the prototype can walk on the vertical wall of various materials. The experiment results of the prototype walking on the vertical steel plate surface show that the maximum load is 13kg. And can span 20x8mm cracks.
