This is an incorrect interpretation by people who want to see Karel Čapek's play "R.U.R."(Rossum's Universal Robots), which famously introduced the word "robot" into the English language, this way. While the root "robot" in Slavic languages goes back to "rab" for slaves, Robotnik (Russian/Polish), Robota (Czech) etc. has simply meant "worker" for ages, without any connotation to forced labour.
Fun fact: The word "slave" is derived from "Slavic people".
