When I tell people I played ping pong with a robot this week, the first thing they ask is: "Did you win?" I tell them that winning isn't really the point. Though if we'd kept score, I probably did.

The whole aim of Forpheus is to coach you on improving your game. The robot uses sensors on your bat (aka paddle) and four cameras to work out where you are and how you're moving. It plays using a multi-axis robotic arm that can mimic human tactics such as topspin. Feedback arrives via voice and on a screen, which offers tips about posture, positioning and swing. After just a five-minute session, I was wondering where Forpheus had been all my life.
