Robots are usually used to do repetitive work which requires high precision. For instance, robots are used to produce cars. Later, robots may also perform surgical operations on humans. A computer could direct the procedure with excellent precision. Meanwhile, human surgeons could control the progress by monitoring the operation on a large video screen.
