Here’s the big difference in the wording:
G38 ROBOTS may not control more than one (1) BOULDER at any time.
Violation: FOUL per extra BOULDER
Examples of interaction with BOULDERS that are not “control” include, but are not limited to:
A. “bulldozing” (inadvertent contact with BOULDERS while in the path of the ROBOT moving about the FIELD)
One GAME PIECE at a time. ROBOTS may not have greater-than-momentary or repeated control, i.e. exercise greater-than-momentary or repeated influence, of more than one (1) GAME PIECE at a time, either directly or transitively through other objects. A GAME PIECE that is at least partially supported by a ROCKET or CARGO SHIP is not considered controlled by the ROBOT.
It was easy for refs to see teams stuck on a boulder as “inadvertent contact while moving around the field”, even though I don’t think anyone in their right mind would label it as “bulldozing”, using the dictionary definition of the word. There isn’t that wiggle room in the rules this year - the “greater-than-momentary” part is probably intended to take the place of the bulldozing example from 2016… and it does, if the intent really is “bulldozing”, and not what we extended the definition of it to mean that year.
That said, I would be in favor of a change that exempts this sort of unintentional, temporary, and ultimately harmful (even without the penalty) “control”.
