(Incidentally, if a connection allows motion, it's "articulated"—preventing the motion doesn't overcome that condition, at least if "articulated" is meant to be adjectival. The other interpretation of "articulated" is in the sense of the past tense of a verb. I don't know which interpretations FIRST had in mind.)

I didn't look in detail at their robot (I didn't inspect it), but I don't believe their frame is articulated. That would be a violation of R01-2. Their bumpers aren't articulated; that's R30. If their drive train changes position with respect to itself is not any kind of issue; there's no rule against it.
