Gyros and Field Centric Control

[skimoose]

Ether has pointed you in a good direction. To elaborate, you need to select a gyro with sufficient degrees/second response. A good minimum is 300. If your robot can turn faster or be struck and spun faster than the gyro can respond, your field centric controls will lose their bearing. There are several gyros available from Sparkfun with the correct input voltage. If you use a gyro that is close to your turn rate, you can always program a gyro reset into your operators controls. If the robot drifts off axis, the driver can manually position the robot back to a bearing of zero and hit a button to reset your bearing variable to zero as well.
