R.U.R. (Rossum's Universal Robots)
Science fiction play by the Czech writer Karel Capek (1890-1938),
which is credited with introducing the word "robot"
(from the Czech robota meaning "servitude" or "drudgery") into
English, although the creations it depicts would now be called androids.
The robots were designed to be economical workers who, because they lacked
emotions, would be easier to handle , more dependable, and cheaper than
their human counterparts. However, the intended exploitation of the robots
doesn't go to plan, and Capek used their revolt as a stage for his view
on human relationships.
