Design and simulation of a wall-climbing robot car using 3D printing technology and the vacuum method

This paper presents a novel approach to building a vertical wall-climbing robot using the vacuum method and the internal contact model. By leveraging advanced 3D printing technology, the proposed robot model addresses three key challenges encountered in previous studies: achieving high traction force for smooth and efficient movement, ensuring low roughness and fast shifting capability, and minimizing production costs for mass deployment. The vacuum suction method employs an air compressor to generate suction force, enabling the robot to ascend walls vertically. This process significantly increases airflow velocity, creating a low-pressure area that enhances adhesion to the surface. The utilization of 3D printing technology allows for the creation of the robot's bodywork and essential components, facilitating adjustments in the mechanical system design. The developed robot is well-suited for inspecting and maintaining hazardous areas in tall buildings and conducting surveillance in factory settings. Moreover, it proves valuable for cleaning and monitoring slippery surfaces with minimal roughness. The research findings demonstrate that incorporating 3D printing technology in the design and construction of wall-climbing robots has successfully achieved the desired speed and grip capabilities.
