Drawbridge Technique: Legal or not?

[Mr V]

When we tried that method we certainly wondered if it would be considered legal but fully expecting that for it to count it must be obvious to the ref or scorer that contact was broken.

I think it would be the quickest way to breach the draw bridge. Do another defense on your way to score a boulder and on the way back do a quick double breach.

This was also discussed last week here:

Based on the Q&A feedback, most CD posters agreed that it is indeed legal

Do you have to clear the drawbridge for a certain period of time before touching it again?

There is no set time period. However, due to the definition of Crossing (and the fact that the Crossings are scored by humans), you'll need to clearly not be touching in order to get credit.

Fixed it for you.

Just wondering if anyone has built the team version draw bridge, what springs did you use? The ones we have (Home Depot screen door 16") aren't strong enough to shut the bridge after it goes down.

Also, What if one robot drives through and holds a defense open for another robot(s), sort of like tag-team wrestling? How could this not be legit? Robots working together to accomplish goals seem to be in the spirit of FIRST.

We use water-filled 1-gallon orange juice jugs attached via rope to the drawbridge through a pulley. It takes slightly more force to lower it, but it has generally worked for us.
