IMU Sensor
An IMU sensor (Inertial Measurement Unit) is a device that measures a robot or object's motion and orientation using:
Sensor | Measures | Unit |
---|---|---|
Accelerometer | Linear acceleration | m/s² |
Gyroscope | Angular velocity (rotational speed) | rad/s |
Magnetometer (optional) | Magnetic field for heading (compass) | µT |
- 6 DOF IMU, combining a 3-axis accelerometer and a 3-axis gyroscope.
- 9 DOF IMU, adding a 3-axis magnetic compass.
- 10 DOF IMU, which adds a barometer for estimating the sensor’s altitude.
