The year is 2045. A group of robots take part in the World Cup. Robots? Is that possible? Many scientists believe it can happen, because there are already robots that can play football. Of course, today's robots don't just play sports.
Early robots could do easy things, mainly in factories. Humans operated (操作) them. However, today's robots can operate on their own. Some can only move around a little, like the robots which can sweep the floor, but others, for example, Honda's ASIMO can do much more. He can run, climb, dance, and even play football.
Then there are robots which look like humans. These robots have faces and can show feelings. Such robots can learn new things, and show us how they "feel". Actroid -DER is one of them.
Scientists are also making robots that look and act like animals. At NASA, scientists are making a robot snake which can get into holes (洞). One day, it may help scientists look for signs of life on Mars. There are other animal robots. The frog-bot can jump over things. The sticky-bot can walk up walls. There's even a robot called Water Runner that can walk on water.
But can a robot football team ever play as well as a human team? Many scientists think so. Anything is possible. One day, they may even be world champions (冠军)!
