Unit 12: IMU & Rotation
This unit teaches students to use the IMU built into the REV Control Hub for real-time heading data, field-relative motion translation, tilt detection, and closed-loop autonomous turning. Initialize the REV Hub gyro, read Yaw for heading control, implement field-centric driving, monitor Pitch and Roll for tip detection, and build a proportional autonomous turn.

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.
