Are there any teams out there that use closed loop control (for operator driving) in any way in the teleop period? This could be joystick values to speed reference, current reference, power reference. Closing the loop on heading, anything. I think most teams basically map joystick displacement to percentage of battery voltage and let the driver close the loop. I understand that many teams use closed loop control for automated scoring sequences etc. I am interested in operator driving.
the gyro is used by several (many?) teams for field-oriented control

The Poofs usually do, and I’m sure they are not alone. See http://www.chiefdelphi.com/forums/showthread.php?t=98267.
We have never done it during teleop because it requires a bit of time to fully tune and get desired behavior, and time is something we’re usually short on. And we usually don’t have dedicated software people (plenty of people who can program pretty well, but they’re busy with other things too).
We did field centric last year 2011.discobots.org
