1. Make sure you can cross the bridge. (Standard kitbot will do this effectively)
2. Make an arm to knock down the bridge.
3. Practice balancing on a bridge if you can. The easier it is for you, the higher chance you have of being picked when everyone else sees how easy you can balance.
4. Echoing what Dustin said but make your robot small and easy to fit on the bridge for a triple balance.
5. In terms of simplicity and still being valuable see if you can make a hopper on the top of your robot with a roller to spit balls onto the floor so you can collect from the human players and take the balls to a scoring robot on your alliance.

Good luck!
