The Mecanum wheel is applied to the AGV"s motion system to provide three degrees of freedom in the plane. Since the direction and speed of movement of the AGV depends on the motion of each Mecanum wheel, the AGV tracking motion needs to be more precise.In order to overcome the problem of deviation from the predetermined path in AGV operation, a tracking correction method based on fuzzy control is designed to correct its actual driving trajectory. The simulation experiment and actual detection are carried out to verify the effectiveness of the designed fuzzy controller.
