In some science fiction (科幻)movies. people in the future have their own robots. These robots are like humans (人类). They help with the housework and do difficult and heavy jobs.
Some scientists think that there will be such robots in the future. But they say it may take hundreds of years. Scientists are now trying to make robots look like people and do the same things as us. Japanese companies have already made robots walk and dance.
James White thinks that it will be difficult for a robot to do the same things as a person. But other scientists don't think so. They think robots can do the same thing as us in 50 years.
Robot scientists are trying to make robots look like not only people but also animals. For example, there are already robots working in factories. They do easy jobs over and over again. People would not like to do such jobs and would get bored(感到无聊的). But robots will never get bored and tired.
In the future, there will be more robots everywhere, and humans will have less work to do. New robots will have many different shapes(形状). Some will look like humans, some will look like dogs, some will look like hands, and others may look like snakes. After an earthquake (地震), a snake robot could help look for people under buildings. We never know what will happen in the future!
