| Research Abstract |
Aiming to develop small flapping aerial robots capable of hovering flight, we measured wing motions and shapes of a real hummingbird in hovering flight using multiple high-speed video cameras and motion analysis software. To realize wing deformation like the real hummingbird wing in artificial wings with light-weight structures and mechanisms, the wing films was relaxed in order to enhance passive feathering deformation. As a result, the wing with the relaxed film generated higher average lift than the wing with a tight film, which was comparable to the body weight of the hummingbird. The relaxed film also improved efficiency represented as a ratio of average lift to input power.
