People are fascinated by robots. Some of them look like mechanical dolls to play with. Most of them look like other machines of today's technology. One of the advantages of robots is that they can work in situations that are dangerous or harmful for human workers. For example, the continuous smell of paint has a harmful effect on painters, but it doesn' t bother a robot. Robots can work in nuclear power plants and in undersea research stations that might be dangerous for humans. There are robots in the plastics industry and in chemical industry and industrial equipment industries. One of the most common uses of robots is in automobile factories. They can do the heavy, unpleasant, or dangerous work. For example, a computer programmer writes a program that tells how much paint to use, how thick it must be, and the size of the car body. The robot does not waste any time or movements. It never becomes bored. It doesn't need a coffee break. It lasts 20 to 25 years. Today' s robots are simple-minded compared with the ones of the future. Researchers are now working on the sixth generation. These new robots will be able to take information from the environment. They will be able to see, using television camera for eyes. They will be able to touch and hear. Some computers can already understand a limited vocabulary. Researchers are trying to develop ones that can understand human speech. They will be able to understand voice commands and then respond. The new robots will be able to move in more ways. They will have several arms, each will several fingers. The robot will be able to operate these arms and fingers by itself. It will be able to make complex decisions in a working environment.
