An Inertial Measurement Unit (IMU) is a device that helps measure and track the motion of an object. It typically combines sensors like accelerometers and gyroscopes to detect changes in speed, orientation, and direction. IMUs are widely used in various applications, from smartphones to drones and automobiles, providing essential data for navigation and stability. These units work by sensing the forces acting on them and calculating the object's position and movement over time. By integrating the data from the sensors, an IMU can help systems like robotics and aerospace vehicles maintain balance and navigate accurately, even in challenging environments.
