A vision based air hockey system with fuzzy control

"Air-hockey" is an interesting table game. Two sides' players hold the paddle trying to strike the puck on the table into the opponent's goal to get scores. This paper tries to implement the whole air hockey system. The system hardware is composed of a robot, a CCD and a PC. The CCD catches the image of the puck on the game table. The PC processes the image to identify the puck's location and estimate the puck's sliding speed and route such that the robot can strikes the puck precisely. The robot movement and its paddle operation are controlled by the technique of fuzzy logic. In the final experiment, we show that the robot play the air hockey game with human beings in a standard (not too fast) puck sliding speed.
