gyrostat
Rotation-based balance keeper
A gyrostat is a device containing a spinning wheel or disc mounted in a frame, designed to maintain a fixed orientation or resist changes in direction.
It operates on the same principle as a gyroscope but is typically enclosed and used in mechanical systems for stabilization: The ship's gyrostat helped reduce rolling in heavy seas.
