Gyroscopes

Definition: A gyroscope is a device used to measure or maintain orientation and angular velocity. It consists of a spinning wheel or disc in which the axis of rotation is free to assume any orientation.

Types

• MEMS Gyroscopes: Micro-Electro-Mechanical Systems – compact, low-power, used in smartphones and drones.
• Optical Gyroscopes: Includes ring laser and fiber optic gyros – high precision, used in aerospace.
• Mechanical Gyroscopes: Traditional spinning mass – used in navigation systems.

Applications

• IMUs (Inertial Measurement Units)
• Drone stabilization
• Smartphone screen rotation
• Aircraft and missile guidance
• Robotics for balance and navigation

Key Parameters

Note: Always pair with accelerometer in 6-axis IMU for full motion sensing.
