Artificial Intelligence is called for Al for short. It is becoming more and more popular in our life nowadays. And it has greatly influenced (影响)the ways we live, work and play.
Recently, a scientist has invented (发明)a special robot that can be a table tennis coach (教练).That means people can practice table tennis not only with humans but also with a robot.
Named Forpheus, the smart table tennis robot is quite special. It can study the movements of human players and the speeds of the ball. In this way, it can exactly know the players' skill levels (水平).Then it uses the information to change the ways to play. If the players are just beginners, Forpheus will play in a slow and easy way, but if the players are better ones, the robot will play in a faster and more difficult way. What's more, while playing, it encourages players to try their best with the words like "Good job!", "Come on!" and so on. At the same time, it gives some good advice to improve their skills. So it is both a good partner and a clever coach.
Science and technology (科技) is developing (发展) quickly these days and it's hard to imagine (想象)what will happen in the future. "In the next 20 years, it will be possible that one robot teaches another to play table tennis or even invents another one!" the inventor of the robot said.
