Description

technical field

[0001] The invention belongs to the technical field of bionics, and in particular relates to a mechanism of a wall-climbing robot, in particular to a hexapod bionic wet-suction wall-climbing robot. Background technique

[0002] Bionics is an interdisciplinary subject that combines life sciences with engineering and technology disciplines such as machinery, materials and information, and has distinctive innovation and application. Through the research on hygroscopic insects, based on the principle of hygroscopicity, a new adsorption mechanism - hygroscopic adsorption is designed, and a new type of wall-climbing robot is developed, which has a wide application prospect. According to the wet suction calculation model, mechanical calculation results and experimental data, it is found that the size of the adsorption force is not only related to the composition of the exudate, the roughness of the contact surface and the effective contact area, but also related to ...
