Bit of Canon here. There are no robots in the Iron Empires. Artificial Intelligence, yes, but there’s a social stigma against humanoid robots. There are thousands of peasants who can (and should, in all justice), do the menial labor required for society to run properly.
That said, feel free to push against the canon wherever you wish. Like I’ve said thirty seven times before, there are lots of human worlds, and plenty of sick, twisted inhuman nobles that would deprive their peasants of the slavery they so justly deserve.
