Gyroscope apparatus ( 100 ) having a compact size is disclosed herein. The apparatus ( 100 ) comprises a flywheel ( 402 ) having a centre cavity ( 401 ) and being arranged to be rotated about a Z-axis. The apparatus ( 100 ) further includes two motors ( 300, 350 ) and a gear assembly ( 200 ) driven by the two motors and arranged to rotate two shafts ( 102, 104 ) disposed along the Z-axis, thus rotating the flywheel about a Y-axis which is orthogonal to the Z-axis. Since flywheel ( 402 ) is disposed around the motors ( 300, 350 ) and the gear assembly ( 200 ), the apparatus can be made very compact.
