Worker robots are becoming more popular in industries. Nowadays they can do more difficult jobs in many factories. The use of robots helps factories increase the quality of their products because robots can do the job well for many hours while humans can get tired and bored. Engineers can make robots more effective and useful at home, at school, and at work. However, a robot uses on average about 100 more times energy than a human to do the same job. The latest 20 kg robot can lift 2 kg, but a 5 kg human arm can lift 50 kg.

People are very interested in robots. Some of them look like mechanical dolls to play with. Most of them look like other machines of today's high technology. Serious research on intelligent robots began in the 1960s in several countries. Now we are on the fifth generation of robots. The first robots were very expensive. They cost 500,000 dollars when a worker could do the same work for 15 dollars an hour. By the early 1970s, a robot brain, a computer, cost 300,000 dollars . Today's robots cost from 15,000 dollars to 150,000 dollars. One of the advantages of robots is that they can work in situations that are dangerous or harmful to human workers. Today there are millions of people who work at machines in the world. Robots will replace them. Part of the problem will be solved because of the decrease in the number of births. There will be fewer people looking for jobs. Many people will find changes in their jobs, and they will not like some of them. The students of today must be sure that these changes are good. Robots must improve, not harm, the quality of human life.
