Robots seem very new to most people. But they have a long history. The first one was made by a Greek(希腊人)inventor in the 1920s.You may have seen robots in some fields. The robots in these fields are stronger, faster and much cleverer than people. In real life, most robots are used in factories. They are used to do many dangerous, difficult or boring jobs. Some people can’t look after themselves and robots are used to help, for example, some people can’t see. Many of these people use a dog to help themselves move around. This dog is called a guide dog. Scientists are making a robot to help them. In the future, robot dogs might take the place of these guide dogs.
One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner’s walk. The owner wears a special belt(带子). This belt sends instructions to the owner from the dog, such as“Stop here”, “Turn left” or “Turn right”.
In the United States, another kind of robot helps disabled people to take care of themselves in their daily life. The robot hears the sound of its owner’s voice. It follows instructions such as “Turn the page” or“Make a cup of coffee”.
Robots are also used in American hospitals. At one hospital a robot take meals from the kitchen to the sick people’s rooms. It never loses its way because it has a map of the hospital in its computer memory.
In the future, robots will work in space. But robots will never take the place of human beings(人类).They can, however, help us in a lot difficult ways.
