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 when a worker could do the same work for $15 an hour. By the early 1970s, a robot brain, a computer, cost $300,000. Today’s robots cost from $15,000 to $150,000.

One of the advantages of robots is that they can work in situations that are dangerous or harmful for 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.

What generation of robots are we on now?
