Actually, I thought the gyro was broken, because sometimes it wouldn't drift at all for long periods of time. Then I'd kick the robot and see it respond. The gyro combined with the default gyro libraries from WPI worked pretty well.

This is probably due to two features of your gyro:
1. The bandwidth of the gyro as implemented on that evaluation board.
2. The "auto zero" function, which apparently uses Vref to provide a dynamic estimate of what the true bias is (if you used this feature)
The Tesla came in the blue tote. This is why you should always inventory your KOP before the replacement window closes! :p - sparrowkc [more]
