With the multi-functional requirements of the inspection work and the improvement of the endurance of the inspection, the back pocket is connected to increase the feeding, endurance and loading capacity of the inspection vehicle. However, in the steel structure engineering inspection, most of them are complex curved surfaces, such as various curved surfaces and cylindrical surfaces of the inner arm of the steel pipe.
