the 'gimbal'-ness of the hummingbird's head is incredible...it's eyes are basically decoupled from the body's flapping and stay almost dead still.

Nevermind the application, this is a very intersting bit of research. The details are very fascinating. I found the turbulences in your PIV footage very captivating. It reminded me of Fractal structures. Really impressive

Ma'am how do you reverse the direction of flapping at such high frequencies (which motors are used)?

It's not a motor that changes direction but a quick couple circular drive gear.

@@orange70383 the motor actually changes the direction. There’s a spring attached at the base of the wing, you command the motor to turn and reverse at the resonance frequency of the spring-mass system to achieve the high amplitude. There are other designs using four bar linkages to achieve the flapping motion but this one is not.

Very good for use in hidden places of the Great Pyramid ...

Орнитоптеры. Микродроны. Американские исследователи из университета Пердью представили крошечный дрон, имитирующий полет колибри. Аппарат способен картографировать темные замкнутые пространства, не используя камеры - за счет соприкосновений с окружающими объектами. Подход мог бы пригодиться при проведении поисково-спасательных мероприятий - впрочем, в настоящее время аппарат получает питание по проводу.

This is ancient news, hawk style drones have been in use for at least 2 decades and they use the same wing, tail, body roll for propulsion and agility just like the real thing. They are very light weight much lighter than the real thing and use air current and updrafts to stay aloft in a certain area for a very long time. Real time video, infra-red and a variety of capabilities can be added or changed in minutes. These drones normally stay high enough so as to be out of shotgun range.

This is a different design. Hawk style drones have a vertical stroke plane, i.e. they flap their wings up and down, therefor producing thrust in the horizontal direction, it also uses their wings similar to an airfoil to produce lift. The design in the video have a horizontal stroke place and the wings flaps front and back, producing vertical thrust. This design is more similar to bees and hummingbirds and are complete different from other birds.

just a gimmick, too much TDP to be useful

Different ways to power things, battery tech can also improve, when a government decides to weapons it it will become better
