About Cho x Ro:

Yeah, maybe if Oda were into bestality. Chopper is a reindeer, and Robin knows it. She thinks of him as a pet or like her baby.

About Zo x Ro:

Even if Zoro weren't obviously going to end up with Tashigi because she's a clone of his first love, there is nothing to imply any sort of romantic relationship between Zoro and Robin.
