There is already <G10> making attaching to field structures illegal, so this might already be covered. Besides, what advantage would anchoring yourself with a sunction cup present? You are now unable to adjust your wait to facilitate balancing, and you got up there in the first place so tipping is hopefully not a concern.

It seems very likely to me that the holes are for the balls.

I think it would help because presumably the best strategy to balance 2 robots is to get one in about the right position and move the other one around. The suction cup would mean the one staying still wouldn't slide. It would also be helpful if you had a movable mass on your robot.

Re: The holes in the bridge are for?

The holes are for ball placement.

Q. Re: [G05] Where specifically are the Basketballs placed on each bridge? Is each alliance allowed to select the position of the 2 balls on their own alliance bridge? Where are unused Basketballs allotted to Robots placed on the Coopertition Bridge? Where are the 2 “regular” Coopertition Bridge
A. Balls will be placed in any of the 15 holes in the surface of the Bridge. Exact locations are not specifically defined and will be determined by the field reset crew at the event.
Suction cups are not legal.

Q. If a robot attaches suction cups to the bridge, is that considered grappling a field element?
A. This would be a violation of Rule [G10].

Oh ye of little imagination...

With 3 robots on the bridge, no robot can move in order to balance. Thus the only way to account for differences in weight & c.g. would be to have an arm or slide that can transfer a little bit of weight from one side to the other. It's also much more precise than driving.

Don't think robots will have arms this year? I suspect many teams will have bridge lowering mechanisms powered by motors.

I have been aware since Kickoff of the possibility of a weight shifting device, I simply don't see much merit to it. Even if one were to implement one, the drivetrain would likely be able to hold the robot steady while using it (which, still, why are you doing that instead of driving?) and if you can't move because of other robots, there is no need for an anchor to keep you from moving...
