Gyro Repeatability, Expected Drift ?

[de_]

Ouch. I was hoping there would be a simple answer like yes this is normal or no its defective or something !

Thanks for the suggestions on how to handle it. yes I would love to see the code too.

Being a brand new user of gyros (haven't even had the time to figure out what technology they are based on, obviously not a spinning top), I'm obviously trying to run up the learning curve as fast as possible.

I'm hoping the lack of repeatability may not be a show stopper for the 15 seconds. But I am concerned the rate of the First gyro may be too slow. Its probably too late for us to get a 300 deg/sec one.

Are many teams able to do relative extreme navigating using the gyro (and perhaps the gear tooth for straight travel) ? By extreme, I mean, at least one 90 degree turn or better still three 90s (ie one loop around the course) ?

Kevin, is it possible for you to give a 20 word description of this deadband, its magnitude and how it comes in to play for repeatability ?

Thanks
