When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. The rotor will maintain its spin axis direction regardless of the orientation of the outer frame.Ī gyroscope (from Ancient Greek γῦρος gûros, 'circle' and σκοπέω skopéō, 'to look') is a device used for measuring or maintaining orientation and angular velocity. Note the freedom of rotation in all three axes.
