Here is a table tennis tutor with AI that helps you work on your weaknesses and improve your game. The OMRON FORPHEUS uses an array of cameras to monitor the position of the ball at a higher rate and show where each ball will land.
FORPHEUS has a three-camera system and high-speed robotic arm that moves in response to its AI controller. A motion controller is used to tell the robot how to hit the ball. Machine learning is used to evaluate each opponent’s capabilities. You can catch this at CES.
