Recently, a scientist has invented a special robot that can be atable tennis coach. That means people can learn how to play table tennis notonly with humans but also with a robot.

Named Forpheus, the smart table tennis robot is quite special.Itcan study the movements of human players and the speeds of the ball. In thisway, it can exactly judge the players' skill levels(水平).Then it uses the information to change the ways to play. If the players arejust beginners, Forpheus will play in a slow and easy way. But if the players arebetter ones, the robot will play in a faster and more difficult way. What'smore, while playing, it encourages players to try their best with words like: "Goodjob." "Come on!" and so on. At the same time, it gives some goodadvice to improve their skills. So, it is both a good partner and a clevercoach.
