An inertial measurement unit (IMU) is a device that measures and reports a body's specific force, angular rate, and sometimes magnetic field. It typically consists of accelerometers, gyroscopes, and sometimes magnetometers. These sensors work together to provide data about the object's motion and orientation in three-dimensional space. IMUs are widely used in various applications, including aerospace, automotive, and robotics. They help stabilize and navigate vehicles, drones, and smartphones by tracking changes in position and movement. This technology is essential for systems that require precise motion detection and control.
