Abstract:
A battery-changing transportation apparatus. The apparatus comprises one or more servo electric motors, an electric motor controller, a transportation body capable of being driven by the servo electric motor to move along a predetermined direction, a motion controller and a position information feedback component, wherein the position information feedback component is used for measuring, in real time, information of a position of the transportation body in the predetermined direction and feeding the information of the position to the motion controller. The motion controller is configured to control, based on the information of the position and in a closed-loop manner, the movement of the transportation body in the predetermined direction. By means of the position information feedback component, the positioning control precision of the battery-changing transportation apparatus is improved, such that smooth battery-changing is ensured. Further provided is a positioning control method for a battery-changing transportation apparatus.
