+ * coefficients (note: the tuning variable will not appear until the op mode finishes initializing).
+ * Once you've found a satisfactory set of gains, add them to the DriveConstants.java file under the
+ * MOTOR_VELO_PID field.
+ *
+ * Recommended tuning process:
+ *
+ * 1. Increase kP until any phase lag is eliminated. Concurrently increase kD as necessary to
+ *    mitigate oscillations.
+ * 2. Add kI (or adjust kF) until the steady state/constant velocity plateaus are reached.
+ * 3. Back off kP and kD a little until the response is less oscillatory (but without lag).

+ * Pressing Y/Δ (Xbox/PS4) will pause the tuning process and enter driver override, allowing the

+ * change in the y position during the turn. The offset, or distance, of the lateral tracking
+ * wheel from the center or rotation allows the wheel to spin during a point turn, leading
+ * to an incorrect measurement for the y position. This creates an arc around around
+ * the center of rotation with an arc length of change in y and a radius equal to the forward
+ * offset. We can compute this offset by calculating (change in y position) / (change in heading)
+ * which returns the radius if the angle (change in heading) is in radians. This is based
+ * on the arc length formula of length = theta * radius.
+ *
+ * To run this routine, simply adjust the desired angle and specify the number of trials
+ * and the desired delay. Then, run the procedure. Once it finishes, it will print the
+ * average of all the calculated forward offsets derived from the calculation. This calculated
+ * forward offset is then added onto the current forward offset to produce an overall estimate
+ * for the forward offset. You can run this procedure as many times as necessary until a

+ * measured value. This need only be an estimated value as you will be tuning it anyways.
+ *
+ * 2. Make a mark on the bot (with a piece of tape or sharpie or however you wish) and make an
+ * similar mark right below the indicator on your bot. This will be your reference point to
+ * ensure you've turned exactly 360°.
+ *
+ * 3. Although not entirely necessary, having the bot's pose being drawn in dashbooard does help
+ * identify discrepancies in the LATERAL_DISTANCE value. To access the dashboard,
+ * connect your computer to the RC's WiFi network. In your browser, navigate to
+ * https://192.168.49.1:8080/dash if you're using the RC phone or https://192.168.43.1:8080/dash
+ * if you are using the Control Hub.
+ * Ensure the field is showing (select the field view in top right of the page).
+ *
+ * 4. Press play to begin the tuning routine.
+ *
+ * 5. Use the right joystick on gamepad 1 to turn the bot counterclockwise.
+ *
+ * 6. Spin the bot 10 times, counterclockwise. Make sure to keep track of these turns.
+ *
+ * 7. Once the bot has finished spinning 10 times, press A to finishing the routine. The indicators
+ * on the bot and on the ground you created earlier should be lined up.
+ *
+ * 8. Your effective LATERAL_DISTANCE will be given. Stick this value into your
+ * StandardTrackingWheelLocalizer.java class.
+ *
+ * 9. If this value is incorrect, run the routine again while adjusting the LATERAL_DISTANCE value
+ * yourself. Read the heading output and follow the advice stated in the note below to manually
+ * nudge the values yourself.
+ *
+ * Note:
+ * It helps to pay attention to how the pose on the field is drawn in dashboard. A blue circle with
+ * a line from the circumference to the center should be present, representing the bot. The line
+ * indicates forward. If your LATERAL_DISTANCE value is tuned currently, the pose drawn in
+ * dashboard should keep track with the pose of your actual bot. If the drawn bot turns slower than
+ * the actual bot, the LATERAL_DISTANCE should be decreased. If the drawn bot turns faster than the
+ * actual bot, the LATERAL_DISTANCE should be increased.
+ *
+ * If your drawn bot oscillates around a point in dashboard, don't worry. This is because the
+ * position of the perpendicular wheel isn't perfectly set and causes a discrepancy in the
+ * effective center of rotation. You can ignore this effect. The center of rotation will be offset
+ * slightly but your heading will still be fine. This does not affect your overall tracking
+ * precision. The heading should still line up.
