Re: Have you balanced 2 robots yet

I am one of the people who replied as "Having Serious Problems"

Our strategy team has set a functional requirement that we be able to drive to the bridge from any part of the field, lower it, drive up the bridge, and balance in one attempt, all in less than 20 seconds.

We can do it consistently in 13s... one robot... very significant automated assistance... perfect "lab" conditions.

HOWEVER,

The bridge is slippery as heck... those practicing on a plywood surface instead of lexan may not realize how hard this really is.

We put a LOT of effort into PID, including gyro correction, just to be able to climb the bridge nice and straight, without slipping and sliding. Then there was dealing with the slippage and rolling when the bridge started coming down.

Not to knock anyone down, but most videos I've seen of multi-robot balancing take around 45 seconds to do - even on a plywood surface. My guess is that many attempts will "over-correct" and the bridge will rock the other way, causing another attempt.

Right now, where we're at, balancing 2 robots is a 45 second maneuver...

...and to me, that's a serious problem.
