Robotics is the study of robots, or machines that are designed to do certain jobs. If you're fascinated with robots, you might want to study robotics in college.
Robotics, the branch of science that studies the technology and uses of robots, involves various kinds of engineering and computer programming. While a robot is defined as a machine that can be programmed to do a job, many people interested in robotics (especially science fiction fans) think of them as a mechanical replacement for a human. Robotics comes from robot, from the Czech robotiti, "work or drudge."
