Others? The only others who think he was a robot is us, working from what's implied by the texts. Not only does the term not appear in the texts, where he's taken to be either a divinity or a man wearing a suit of armour on which he declined to comment, it would be absurd, since the Nedes didn't know what a robot looked like to make the comparison in the first place.
EDIT: That's odd, I could have sworn I wrote a reply. Well here it is.
They may, however, thought him to be a man made of metal.
