A flying toy includes a left sector gear, a left wing connector extending radially from the left sector gear, a right sector gear, a right wing connector extending radially from the right sector gear, a drive shaft, a crank piece mounted on the drive shaft to rotate therewith, a crank arm coupled between the crank piece and one of the left and right sector gears, two wing members connected respectively to the left and right wing connectors, and a drive unit configured to drive the drive shaft. The right sector gear is configured to mesh with the left sector gear so as to synchronize up-and-down movement of the left and right wing connectors to thereby result in a flapping motion of the two wing members.

A hovering toy creature having a propulsion system, a control system, a winged body, and a wing actuation assembly. The winged body is mounted to the propulsion system, which is controlled by the control system. The wing actuation assembly is mounted to the winged body, and the wing actuation assembly is powered by the control system. The wing actuation assembly drives the wings in an oscillating flapping motion. The wings comprise apertures permitting air passage through the wing, thus reducing the aerodynamic effect of the flapping motion. In this manner, the wings produce a bouncing flight action, thus creating a realistic flight motion. In another embodiment, the propulsion system comprises one or more rotors in a coaxial arrangement. The hovering toy creature is operated by either a wireless control device or a timer device.

A device configured to be detachably coupled to a toy is described. The device comprises a housing and a wing assembly coupled to the housing. The wing assembly comprises at least one wing configured to rotate about a rotational axis in a flapping motion, and a gear assembly configured to cause rotation of the at least one wing. The device further comprises at least one coupling means configured to engage with a magnetic strip of the toy, thereby facilitating a detachable coupling of the device with the toy.

[Problem] To provide a flapping flying robot that is compact and is capable of performing flight with high mobility.

[Solution] A flapping device 1 has blades 2, 2 and a drive unit 3, and the drive unit 3 includes: a drive source 30; a driven part 10 rotated around a first rotation axial line by the drive source 30; a first vibration excitation member 40 biasing the driven part 10 in a direction opposite to a rotation direction of the driven part 10; and a control unit 60. The blade 2 has: a first blade shaft 20 extending in a predetermined axial line direction and being connected to the driven part 10 on a one end side and connected to be rotatable in a second rotation axial line surrounding direction intersecting the first rotation axial line; a second blade shaft 21 extending in a direction intersecting the first blade shaft 20 and being directly or indirectly connected to the driven part 10 on a one end side and connected to be rotatable in the first rotation axial line surrounding direction; and a blade main body 22 disposed over the first blade shaft 20 and the second blade shaft 21.
