In order to solve the cumulative attitude deviation problem in the long distance lateral movement process of the existing AGV with large aspect ratio,the mechanical structure which could match control scheme was provided,a control method for lateral movement of AGV with large aspect ratio was designed,the attitude adjustment algorithm for lateral driving was given.The visual cameras assembled at the car head and tailstock were used to identify the information of the tracking navigation bar,which were feedback to the control system to judge and adjust the moving attitude of the AGV.Combined with the body offset type,the control system formed a control strategy to realize automatic tracking walking and periodic alignment of the AGV with large aspect ratio.An application example shows that the proposed method can effectively identify and adjust the deviation of AGV with large aspect ratio.
