Team popping a wheelie to get on the bridge
 
I remember watching a team who consistently could pop a wheelie to lower the bridge. Anyone know who that may be? And anyone have any footage of it?

Thanks!

We (25) do it every time. We even do wheelies in autonomous O.o

Betting it was 25.
We did it too at GTR East. Scouts love it.

You can see them a few times in our highlight video ----- http://www.youtube.com/watch?v=TUHXf...ayer_embedded#!

Here's the video of us doing it in autonomous --

Well, we haven't needed to do it consistently because our bridge actuator is plenty consistent, but we did wheelie onto the bridge in a few practices matches at NYC and in one qualification match on Friday of the CT regional. Unfortunately I don't think any videos have been posted online.

Probably 25 in MAR elims.

843 from FLR did it as well. Low CoG and those huge wheels make for some fun tricks!

How possible do you think it is with 4" wheels? I want to attempt this in the offseason, but our base is pretty low to the ground (about 2" of clearance)

My team 1056 did that at the hawaii regional every match. our robot was a dunker and had L.E.D.s if that jogs your memory

Team 1391 was doing it before it was cool. ;)


As an aside, what a blue alliance in that video. A combined seven event wins on it.

Team 3255 had an issue with our wedge in an early match at San Diego regionals. Our driver adapted and started popping gnarly wheelies to get the bridge down. Great improve and got the balance. I wonder if he is sad that the mechs fixed the wedge? :)

It depends on how far back your wheels are; if your robot can't tilt back enough for the front to bring the bridge down, it's a no-go. The other factor is where your CG is located; if it's centered, it's going to be substantially harder to wheelie up, but if it's close to one end of your bot, it's going to be easier.

If you're actually wheelie-ing up, and not using something to prop the front up, don't forget that you have to go away from the bridge, then slam forwards to wheelie up.
