$ ./machinatrix wikt robot | head -2 | fmt -w 40
  Borrowed from Czech robot,
  from robota (“drudgery,
  servitude”). Coined in the 1921
  science-fiction play R.U.R. (Rossum's
  Universal Robots) by Karel Čapek
  after having been suggested to him
  by his brother Josef, and taken into
  English without change.
