What This Unit Covers

Initialize the IMU correctly for any physical Hub mounting orientation using RevHubOrientationOnRobot.
Read and normalize Yaw, Pitch, and Roll data using the AngleUnit class for reliable heading and tilt feedback.
Implement field-centric driving and IMU-corrected proportional autonomous turns that self-correct for battery drop and wheel slip.
