Medical robots are machines that doctors use to help treat people who are sick or injured. They can perform many of the same tasks that a human doctor would do - like measuring a patient's pulse rate or giving medicine. However, they are better at some things than humans, like providing very precise treatments or checking for small details that might be hard for a human to pick up. Medical robots also help doctors to be less tired and relieve them of mundane duties, so the doctor can spend more time with the patients.
