hmm

in Chrono Trigger, there is Robo, who uses "magic" that consists of laser and bomb type attacks, but reading about it the game specifically says he can't learn magic and those attacks don't count.

in Secret of Mana there are Kilroy and Kettle Kin, and while they don't have much magic, they can cast Lunar Boost (Kilroy) and Lucid Barrier (Kettle Kin).

I think there are probably too many examples in Final Fantasy to list. A huge part of the premise of FF6 is magic-infused machinery, and I'm pretty sure that includes some robots (Guardian is one example).
