All,
 
Let's not get carried away with the wild ideas on robot flipping over and landing on the bridge decking. We want to keep not only bridge, but entire sets in tact and in good shape. See official Q&A posting on the field damage and prospect of gluing and "benefit of the doubt call".

As far as Vehicle location at the End of Match, robot can park anywhere in the bridge with its drive wheels/treads firmly touching yellow or red decking. Teams need to discuss strategy of that choice and trade/offs in taking 5 point differential.

Since the red platform is locked on the wall, a robot may be able to "jump" or "handstand flip-flop" onto the platform, similar to BrothersKeeper's robot that flip-flopped over the wall -

That will be awesome!

I'm not sure what you mean by "glued", but the red part of the bridge will be "secured" with Dual-Lock to the edge of the table (or border wall)  per Field Set Up.  See below.

MODEL DETAILS - BRIDGE

Bridge - Dual Lock Needed - Get familiar with the bridge's exact placement before applying Dual Lock, then apply Dual Lock at one or two locations at a time, from south to north.  After the six mat contacts are done, use three Dual Lock pairs to secure the red deck to the border wall (one pair at each end, and one pair at center).  Prop up the hinged black deck by standing its swivel beam's end on the tiny black mark.
