The Most Common Robots.

Most robots are not mobile. The most common robot in the world is the robot arm and most of these move an object less than 2 meters. They stay in the same place and do the same job, over and over again. But this is what robots are really good at. It has been said that robots are better than humans at manufacturing because the first time they do a job will be as good as the thousandth time.

Car building.

Robot arms first became popular in car factories because they do boring and dangerous jobs very, very well. Robots can faultlessly spray paint, among toxic fumes that would quickly kill a person. Robots weld in exactly the right place, every time. Robots make parts and put them together, without ever getting tired, making a mistake or asking for a pay rise.

In the car factory videos, notice that the robots tend to be big and expensive.
