It’s hard to get better at table tennis without a playing partner that can adjust to your skill level. The Forpheus Ping Pong Robot can do just that. It uses two vision sensors and a motion sensor to measure the position of both its opponent and the movement of the ball 80 times per second. Using AI, it can then predict the trajectory of the ball and hit the ball back, and learn about your playing characteristics over time to help you make progress. It’s not available for sale to private or commercial customers just yet but instead points to a future where robots can help you get better at skills you already have, instead of just doing things for you.
