In some ways robots are better than people. They work quickly, but do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired.
So robots are very useful in factories. They can be taught to do many different jobs. At first, their electronic brains must be shown how the job is done. A person moves the robot' s \brain re-members each move. When the robot is put to work on its own, its brain controls the rods, wheels and motors which move its arm. When the robot is needed for a new job, its electronic memory is \do its new task.
Robots are also used for doing jobs which are dangerous. They can move objects which are too hot or too heavy for people to handle. They can work in places which are too hot or too cold for people. And they are not affected by poisonous fumes or gases. In scientific research, they may be used for doing such jobs as handling radioactive materials.
