Fully automatic racket stringing system

An automatic racket stringing system includes: two camera modules, respectively capturing an image of the racket string hole on a racket at a first predetermined position from different two angles, wherein the cameras determine a first relative coordinate of the racket string hole through a triangulation method; and a control unit controls a robotic arm to grab the racket from an initial position and move the racket to the first predetermined position; wherein the control unit controls the robotic arm to a second predetermined position to grip a first end of a racket string, and when the first end of the racket string extends a predetermined length, it is cut by the robotic arm. The robotic arm passes one end of the racket string through the racket string hole and/or the robotic arm ties and knots one end of the string adjacent a racket string hole.
