No, it's not specifically called out as a foul. I can't think of a way to call it as one, either. UNLESS... you could make the argument, somehow, that the transitory property ascribed to the Pinning rule (that is, if there's an object between pinner and pinnee, it's still a pin) also applies to contact with a robot attempting to climb its tower. That would be the only way to even have a chance at calling it, unless someone can dig up a Q&A that says otherwise.

Now, that doesn't seem quite right--after all, they're still interfering with a climb--but that's the way it works.
