The "stationary detection" we did was only necessary when the robot was put on the field but the start of the match was delayed several minutes (yeah, we've all been there).
Mind sharing the model number of that gyro?

Also, you didn't use the pair of follower wheels to try to determine rotation rate while translating, you just used it to detect the complete absence of velocity, correct?
