　　When an automatic washing machine is switched on，water pours in. Themachine waits until the water is hot before washing the clothes. It does this by“feedback．”Information　about What is happening is“feedback”into the robot to te11 it what to do next.
　　Our eyes， ears and other senses are our feedback． They tell us whatis going on around us. So robots are like people in two ways，They work and they have feedback.
　　There are robots all around， making our lives easier. Some of them，like the pocket calculator， can work much more quick1y than human beingscan. And they rarely make mistakes.
