Best Practices
If a short occurs between any of the MXP Expansion I/O pins, the POWER led on the RoboRIO will turn
red, and the navX-sensor circuit board will not receive power.
To protect against accidental shorts, Kauai Labs recommends a protective enclosure that at least partially
encases the MXP I/O pins, such as the
9) If possible, mount the navX-sensor circuit board near the center of
rotation
Since navX-sensor measures rotation, errors in the measured angles can occur if the navX-sensor circuit
board is mounted at a point not near the robot center of rotation. For optimal results, the navX-sensor
circuit board should be mounted at the robot's center of rotation. If the navX-sensor circuit board cannot
be mounted near the robot's center of rotation, small amounts of error that may be noticeable can occur.
10) Use OmniMount
horizontally
By default, the navX-sensor's motion processing requires the unit be mounted horizontally, parallel to the
earth's surface; the yaw (Z) axis should be perpendicular to the earths surface.
If your RoboRIO is mounted vertically, you will need to enable the
reliable, accurate yaw (Z) axis readings.
11) Learn how the sensor behaves by using the navXUI
The
navXUI
provides insight into the key navX-sensor features, and can help debug issues you may
encounter when integrating navX-sensor onto your robot. Running this user interface is highly
recommended for anyone using a navX-sensor. You can even run the navXUI while your robot is
simultaneously communicating with the navX-sensor circuit board via the sensor's external interfaces
(e.g., TTL UART, I2C or SPI).
Several terms used throughout the navX-sensor libraries and documentation may not be commonly
understood and are defined herein.
