　　Technology. of intelligent machines improves amazingly with the help of artificial intelligence.Robots, known as steel-collar workers, are widely employed in different fields, such as marine research, space exploration and some modern assembly lines. Robots bring about advantages undoubtedly, and meanwhile, they are not as versatile as expected.

　　The advantages of robots are innumerable.The employment of robots on assembly lines saves a lot of labor forces. Robots are widely used in developed countries. In Japan, one out of ten thousand workers are robots, which not only improves the working efficiency, but also enhances accuracy. That is the reason why robots are so popular in the automobile industry and electronic production lines.

　　Another merit is that robots can take the place of human beings and work in dangerous environments or places not accessible for people. Human beings have extended their cognition to outer space, where there are considerable unpredictable dangers.Robots can work in any kind of circumstance, no matter how awful the circumstance is. In hospital, robots work as professional doctors performing operations on patients. Furthermore, robots can work around the clock, never knowing what means to be tired.
