Definition :  Robots are machines that can do work automatically.

Movement : Robots move using electrical circuits.  We use computers or remotes to control their movements.

History :  The first robot was made in the fifth century BCE.  We first started calling these machines robots because of a Czech play in 1920.  Robot means work in Czech!

Feelings : Robots don't have emotions, but they can be programed to make them "see," "hear," and "feel" things around them. 

Androids :  Robots that look like people are called androids. 

Uses :  We use robots to do jobs that are too dangerous for people, like finding hidden bombs. We also use them to explore places people can't go, like space, the deep sea, and volcanos.  Sometimes, robots also do the boring, repetitive jobs in factories.

Thinking :  We don't know if robots will ever think for themselves.  Many robots are already really smart- some can even learn from their mistakes!
