Abstract
A robot tool for automatically lifting/lowering a vehicle, including a control system, an image system, a plurality of jacks and a driving device. The image system has aiming devices and can capture images above the jacks. The control system can exchange data with the outside world and store data which includes commands, setup information, characteristic parameters and images of vehicles. The control system can obtain positioning images from image system containing information of relative position in horizontal direction between vehicle lifting points and the corresponding jacks. The control system can analyze said positioning images and compare them with the received data to navigate said driving device to move said jacks horizontally, so that each of at least two lifting points of said vehicle can be vertically aligned by a jack below, said control system is capable of operating the jacks to raise or lower the lifted vehicle.
