Robots are machines that can automatically perform both simple and complex actions. They are often programmed by a computer, but there's no single definition of a robot. Robots include a wide variety of machines, such as the giant arms used to make cars, automatic vacuum cleaners, humanoid machines that look like people and do backflips, and robotic dogs.
