Definition of gyroscope in English:

noun

A device consisting of a wheel or disc mounted so that it can spin rapidly about an axis which is itself free to alter in direction. The orientation of the axis is not affected by tilting of the mounting, so gyroscopes can be used to provide stability or maintain a reference direction in navigation systems, automatic pilots, and stabilizers.
Example sentences
  • When the axis of a gyroscope is rotated the gyro attempts to make the plane of the rotation of the axis become the new plane of rotation for the gyro.
  • The chair uses a computerized system of sensors, gyroscopes, and electric motors to convert itself from a standard four-wheeled chair to an elevated chair balanced on only two wheels.
  • These guidance systems consist of a small spinning device called a gyroscope which keeps a constant axis orientation and thus helps to orient the missile.

Origin

mid 19th century: from French, from Greek guros 'a ring' + modern Latin scopium (see -scope).
