Gyroscope

Definition

A gyroscope is a device that uses angular momentum to maintain orientation and stability, often relying on the principles of physics to sense changes in position. These devices are crucial in providing feedback on motion and orientation, which is vital for navigation systems and robotics. By measuring rotational motion, gyroscopes enhance the ability of machines to understand their position in space, complementing other sensors used for feedback.
