Mecanum wheel wall-climbing detection robot based on magnetic attraction technology

According to the technical scheme, the Mecanum wheel wall climbing detection robot based on the magnetic attraction technology comprises a main body, the front side and the rear side of the main body are each provided with two rotating shafts, the rotating shafts are connected with the main body through bearings, the outer sides of the rotating shafts are fixedly sleeved with electric hubs, and the outer sides of the electric hubs are fixedly sleeved with Mecanum wheel bodies; tyres are Mecanum wheels, an electromagnet is embedded in the bottom of the main body, a containing groove is formed in the top of the main body, an electric power storage plate is fixedly arranged in the containing groove, and a programmable logic controller (PLC) is fixedly arranged in the containing groove. The Mecanum wheels can enable the robot to achieve front-back and left-right translation and in-situ rotation, the flexibility is improved, the wall-climbing robot can detect the surface of a structure by carrying a camera and a c
