The flow-optimised design of the artificial ray increases its aerodynamic efficiency, while the active twisting of its wings ensures that their full force is used in the air. A servo motor pulls alternately on the two flanks in the longitudinal direction and thus moves the wing up and down in a targeted manner.

With an additional servo drive, the beating wing can be rotated in its transverse axis, which means that the Air_ray can also be manoeuvred backwards. The motion sequence comes very close to that of its biological role model.
