The Greek roots

The story of the word
Homer's automatoi gates of Olympus swing open with nobody touching them, and the same adjective covers a plant that grows unsown and an event nobody arranged. The second half is not motion, whatever it looks like: it belongs to a verb of eagerness and will, kin to Latin mens. English took automatic in the 1700s for machinery, and the automatic pistol, the automatic transmission and the automatic teller followed, each one further from the will the word started with.
