Abstract

Abstract: Aiming at the problem of low wall adsorption capacity of the wall-climbing robot, this paper designs a negative-pressure climbing wall tracing robot; the structure of the robot is designed, and a double-wheel differential control driving mode is determined; The key technical parameters are analyzed theoretically, and the calculation method of the minimum pressure difference and the minimum distance of the chassis from the ground is obtained. The numerical simulation of the negative pressure generator based on Fluent verified the rationality of the structure of the negative pressure generator. The distribution characteristics of the pressure in the negative pressure generator are displayed and analyzed. Finally, the physical model of the robot is built and the feasibility of the design is verified.
