Isaac Asimov is one of the most famous science fiction（科幻小说）writers of all time. He moved from Russia to the United States in 1923.He was a teacher at Boston University and began writing science fiction stories in 1939.His most famous works are the Foundation books and the Robot stories. He died in 1992 at the age of 72.

"There are not many people who have invented a useful scientific term，and although I did it unknowingly，I am not going to let anyone in the world forget it，"said Isaac Asimov. He was talking about the word "robotics" —the study of robot behaviour.

Asimov wrote several stories about robots between 1940 and 1990.One of the special features of the robots in these stories was that they were programmed to follow the Three Laws of Robotics.

The First Law: A robot must not hurt a human being，or allow a human being to be hurt.

The Second Law: A robot must obey orders by human beings unless these orders conflict（冲突）with the First Law.

The Third Law: A robot must protect itself unless this conflicts with the First or Second Law.

In Asimov's stories，the robots must follow these laws so that they do not attack the humans that created them.

Some scientists think the Three Laws of Robotics are hard to realise in real life. On the other hand，some say that the laws are great for science fiction but completely useless in real life. For example，if the laws really worked，robots couldn't be used in wars，as this would break the First Law. Since the army is one of the biggest supporters for robotic research，it is very unlikely that an attempt to follow these rules will happen.

According to Asimov，one thing is certain："Robots are changing the world and driving it in directions we cannot clearly foresee（预见）."
