Study Notes
Inertial Measurement Unit (IMU)
- An IMU measures orientation, angular velocity, and linear acceleration.
- IMUs are used in various systems that require motion tracking and navigation, such as robotics, drones, autonomous vehicles, spacecraft, and wearable devices.
- IMUs detect changes in velocity to measure linear acceleration using accelerometers.
- A magnetometer is included in an IMU to determine the orientation of the system with respect to Earth's magnetic field.
- When used in conjunction with GPS devices, the IMU provides information about the orientation and acceleration of the device, improving the accuracy and reliability of position and time calculations.
