The word robot comes from the Czech word ‘robotnik‘ which means forced labor or even slave.
The word was first introduced by playwright Karel Capek in his play ‘RUR - Rossum’s Universal Robots‘ and it’s from there that the word and idea became popular.
The first robot to be developed was by Joseph Engelberger and George Devol back in 1961, it was basically a clawed arm that dropped hot steel car parts into water for cooling.
90% of robots today are used in factories, working on production lines and often handling dangerous materials that humans would find difficult or even impossible to handle. Other uses include exploration such as deep sea exploration and mining.
That was a nice list of facts,
