PURPOSE: A multi-gantry robot system for cutting a steel plate is provided to automatically cut three dimensional position of a driving cutting starting point and a width direction cutting starting point by automatically recognizing. CONSTITUTION: A multi-gantry robot system(100) comprises a first cutting gantry robot(20), a second cutting gantry robot(40), sensors, and a control unit(80). The second cutting gantry robot accompanies along the driving cutting direction of the first cutting gantry robot, cuts a steel plate in a width direction, and cuts a scrap. The sensors are adhered to a torch member of the first and second cutting gantry robots and recognizes an outline shape of the steel plate or a starting point of the steel plate and the scrap. The control unit practically controls the driving of the first and second gantry robots.
