AI Overview
An Inertial Measurement Unit (IMU) is a sensor device measuring an object's specific force, angular rate, and orientation using
accelerometers, gyroscopes, and often magnetometers
. Typically providing 6 to 9 degrees of freedom (DoF) across X, Y, and Z axes, it is critical for tracking motion, navigation, and stabilization in robotics, drones, and smartphones.
Core Components and Functions
- Accelerometers (3-Axis): Measure linear acceleration (specific force) to detect speed changes, orientation, and tilt, often affected by gravity.
