Though I would say "little compensation beyond energy and maintenance" misses the point. The compensation is we could make it fun for them... orgasmic even. (Assuming by "as smart as humans" you are saying they are sentient. If no sentience, there's no point worrying about what they think, they won't care either.)

There's no test for sentience, but they are robots who seem to be self-aware so they very well might be. Let's just say they are.
