Because vertical wall operations are beyond the limits of humans, they are also called extreme operation robots abroad. A wall-climbing robot must have two basic functions: adsorption and movement. Common adsorption methods include negative pressure adsorption and permanent magnetic adsorption. The negative pressure method can adsorb on the wall by generating negative pressure in the suction cup, and is not limited by the wall material; the permanent magnetic adsorption method includes permanent magnets and electromagnets, which are only suitable for adsorbing magnetic conductive walls. Wall-climbing robots are mainly used in petrochemical enterprises to perform flaw detection or painting of large cylindrical tanks, or to clean and spray buildings.
