A robot has, or seems to have, it's own ability to move; something "mechanic" often communicates that a human is it's motivating power (fx. A bicycle).

So exactly as I said, thanks. But the line can be pretty thin🤔 At some point I was thinking if they're not the same thing from a different point of view, a robot and a machine. My kid really got me on that one.
The word "Robot" comes from the Russian/slavic "Rabotnik" meaning "worker", this understood as a "worker machine".
It's possible. It was invented by our writer Čapek, first used in his R.U.R. novel. Those were real humanoid robots. It makes sense the word comes from other roots of ours.🤔 Definitely a good point, I never realized the root of the word.
