I think you don't understand the vast chasm between robotic capability and humans, and what can reasonably be done to close that gap. You're talking about making some sort of robotic geologist/biologist in the literal sense -- a humanoid robot or equivalent functionality that is space hardened, resists abrasive dust like nothing we have on Earth, requires no on-site maintenance, and is autonomous enough to operate for 10's of minutes at a time as good as it would be if humans were at the helm and it was next door.

I don't think you understand the scale of those requirements. It would be cheaper to send humans, even at absolutely ridiculous Apollo-on-steroid prices.
