Robotics is a part of Engineering and Science. It has to do with the creation and building of robots, as well as computer programming. It is interdisciplinary, using mechanical, electrical and other kinds of engineering. Robots are sometimes used to do things that humans cannot, like finding and destroying bombs are, or going where humans can't. Some robots look like humans, but most just look like machines.

Robotics comes from the word robot, which in turn comes from the Slavic word robota. Robota means labor, or work. Josef Čapek invented the word robot to use in a play. This play was called R.U.R. (Rossum's Universal Robots). The word robotics was first used by Isaac Asimov in his story "Liar!". This story was published in 1941.
