The mobile platform using Mecanum wheels achieves omnidirectional movement through the cooperation of the four wheel speeds. Therefore, the movement of each wheel will affect the overall movement direction and speed. In the case, once one of the wheels lost contact with the ground and slipped, the moving direction of the entire mobile platform would deviate greatly. Aiming at the problem of deviation of magnetically guided Mecanum wheels omnidirectionally moving Automated Guide Vehicle(AGV) along the predetermined route, a path deviation correction control method based on attitude and angle sensors was designed. The collected deviation data was used as input to the AGV driving path for correction. The validity of the method is verified by experiments.
