AGV is the key equipment for the flexible and intelligent modern logistics system. This paper mainly designs the system of magnetic navigation AGV, including structural design and control system. In the structural design, the differential steering six-wheel running mode is adopted, and the three-dimensional design software is used for the modeling design. The control system adopts the MCU as the control unit. Based on the magnetic navigation, the fuzzy control is used to realize the driving speed adjustment to ensure that the AGV runs on the predetermined trajectory, so that the AGV has strong stability, fast response speed and automatic correction in the work. Ability. Finally, the corrective ability of the AGV is verified by simulink simulation.
