Robots are sometimes used to do things that humans cannot, like finding and destroyingbombs, or going places that are too hot, small, dangerous or distant for humans.[2] Some robots look like humans, but most just look like machines. Some robots can move by themselves, others need to be partly or completely controlled by a human.[3]
Robotics comes from the wordrobot, which in turn comes from the Slavic wordrobota.Robota means labor, or work. Karel Čapek invented the wordrobot to use in a play. This play was calledR.U.R. (Rossum's Universal Robots). The wordrobotics was first used by Isaac Asimov in his story "Liar!" published in 1941.
