Let me first say that watching your video has allowed me to really appreciate the engineering that went into every single piece of your robot. There is alot to learn from what you guys do every year.
Upon further review of the bridge manipulator, I have stubbled upon something interesting. Is your mechanism capable of hanging from the low cost option of the field as provided to us here:

I would think that the low cost field is designed to test out all of the games rules and therefore holds some intent of the rules inherently. This also supports the rule against trolling.
