Robot etymology is from Czech robota, robotník, robotiti. To work, worker, to do work. I especially like "road works" signs in Poland saying "uwaga roboty drogowe" and translate/visualise it in my mind like "Danger robots on the road"
We don't really go around calling ourselves "slavs". And even "slavic" is kinda a scientific word.
I'm not sure that even that many people connect the dots, and even if they do it's a far history.
