Guidance
To ensure the highest possible accuracy and reliability, several
recommendations regarding installation and use are provided.
This includes a set of
operation.
VMX-pi also features several calibration processes to ensure easy-to-use, high-reliability
operation. This includes automatic

calibration. This section discusses these calibration processes and the theory
behind them, including how to ensure minimal
This page summarizes the recommended best practices when integrating VMX-pi with a robot,
such as a FIRST FRC robot. Following these best practices will help ensure high reliability and
consistent operation.
1) Secure VMX-pi circuit board to the Robot Chassis
Excessive vibration will reduce the quality of VMX-pi orientation sensor measurements. The
VMX-pi circuit board should be

2) Understand and Plan for Calibration
Gyro/Accelerometer Calibration
to understand this process, and ensure that it completes successfully each time you use the
robot.
If your robot moves during calibration, or if noticeable temperature changes occur during
calibration, the calibration process may take longer than normal.
