Seconding what Freelance said. "Clockwork Servitors" or "Mammets" is what you're going for. These are made by Goldsmiths with a bunch of tiny parts and silver/gold metal bits to conduct the inner works of however exactly they function. What gives them a seeming... sentience or personality is their Mammet Core. We don't know exactly how the minute details work, only that it does and is represented quite a bit in lore. I'd look into the various Minion descriptions on Gamerescape or in your own Minion Guide. There's some tidbits on there about mammets and how they function and such. ^^
