Robot Beats Humans at Table Tennis
A robot can play table tennis very well. The robot is called Ace. A big company from Japan, Sony, made it. Ace played against very good players. It won three of five games. The games used real rules. One player said Ace hit a ball in a way he thought was impossible.
Ace uses cameras to see the ball. The cameras watch how the ball moves and spins. Ace learned to play by practising 3,000 hours on a computer. Sony made sure Ace plays fair. It does not hit the ball too fast.
Some people are excited about this robot. It is the first time a robot plays a sport this well. But some experts say the cameras give Ace an unfair advantage. Humans only have two eyes. Players also say it feels strange to play against a machine.
