With a click and a whirr, a robot keeps busy in the factory. It joins steel panels together. All day long it works on brand-new cars.
Some robots push a metal pin called a rivet through metal sheets to join the pieces together. Others are welders. They heat the edges of the metal very quickly so that they melt and join together.
There are no humans working these robots. These robots work by themselves.
How are robots able to join the parts correctly every time? First, a human teaches the robot to do the job. As the human moves the different parts of the mahine in and out, up and down, reaching out and twisting around, every movement is recorded by the robot’s microprocessor. Now the robot has all these movements in its memory. It knows exactly what to do every time a car is put in front of it. As long as the cars are put in exactly the same place each time, the robot will move into action and carry out exactly the right movements for riveting, welding, or even spray-painting.
