The holes in the bridge are for?

This question has been answered on the Q&A:

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.

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

"Quick! Everyone lean left!"

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...
