When slightly angled, the two inner walls of the C-shaped appendage merely react the load of the robot against the inside of the angled bridge rail and the outside features of the bridge. We believe this two point reaction of a fixed mechanism to support our robot weight falls within the intent of the rules because it is clearly written that robots may push or react against any element of the Arena. This simple reaction of forces is demonstrated by the robot being removed from the bridge simply by lifting it straight up. Our intention was actually to drive along the rail while maintaining this two point reaction... an engineering challenge we have not yet been successful at achieving with a fully weighted robot.
If the team wouldn't mind, could 118 post some pictures of the bridge-balancing appendage?

Amazing robot, and blown away by this simple application of forces. Great job.
