The steering wheel integrates the integrated mechanical structure of driving motor, steering motor, reducer, etc., integrating product, walking, traction and steering functions, and can load and pull heavy goods. AGVs, mobile robots, etc. can be quickly deployed. Perfectly meet the application requirements of AGV. Therefore, steering wheel drive is the development direction of AGV applications. Compared with the traditional AGV car differential control method, the steering wheel is highly integrated, adaptable, and has higher precision and faster response with the servo system.
