Understand and Plan for Calibration

NOTE: If using a navX2-sensor, the navXConfig utility provides tools to calibrate gyroscope and accelerometer for optimal accuracy. The navXConfig tools are more comprehensive than the Automatic Gyro/Accelerometer Calibration.

Automatic Gyro/Accelerometer Calibration is vital to achieving high-quality navX-sensor readings. Be sure to understand this process, and ensure that it completes successfully each time you use the robot. Even though it occurs automatically, certain conditions must be met to ensure proper operation.

If your robot moves during calibration, or if noticeable temperature changes occur during calibration, the calibration process may take longer than normal.

Using the navX-sensor yaw angle before calibration completes may result in errors in robot control. To avoid this situation, your robot software should verify that calibration has completed (e.g., by calling the isCalibrating() function) before using navX-sensor data.
