The flow-optimized design of the artificial ray increases aerodynamic efficiency. The active rotation of its beating wings ensures full power development 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 maneuvered backwards. The motion sequence comes very close to that of the biological role model.
