A robot is a machine that does work for people. The word ‘robot’ appeared in the 1920s and it<br>was first used in a science fiction story. In real life, the robot was invented later, in 1954. There<br>are different kinds of robots which are used in different industries. Most of them are operated<br>with the help of a computer program. Instead of humans, robots do hard and boring work in<br>unpleasant or dangerous environments. They usually work faster and more accurately than<br>people. They never get tired and do not make mistakes. Nowadays robots are often used for<br>domestic needs.
