I noticed, years ago, when I raised Hawks and Owls, that a bird's feathers were made to allow air to flow through the wing when the bird raises its wings by sort of twisting each feather and then, on the down swing the structure of each feather works kind of like a stop valve because of the way the feathers grow, with the trailing edge bumping into the leading edge of the feather behind. I noticed this because of the way the bird would groom its feathers. With its beak running, from the attachment point, along the trailing edge of the disarranged feather toward the outward tip of the wing. This would not only correct relation of the feather to leading edge of the following feather but would correct all the little "feather-lets" back into position. It was a thing of beauty.

I own 3 birds and have had the chance to study their wings up close. The magic is not so much in the wing itself but the feathers. The robotic swift is good but the feathers were more uniform than in a bird. Most of the flight power in a wing is managed by just 4 primary feathers. Wing shape is managed by a larger number of secondary feathers and aerodynamics is handled by small feathers called coverts. Together these make an amazing dynamic and ridiculously light system.

Designers and engineers have always looked at nature for inspiration (biomimicry). Festo really has been on the cutting edge of this for many years.

So, the primary advantage of quadcopter drones is ultimately maneuverability. They can be quite stable in a hover and can quickly translate or rotate in any axis at any time. Most of these flapping wing drones require forward movement to stay airborne, which is quite a bit more like a fixed wing airplane, which we have had remote controlled versions of for a long time.

Take-off can be a bit scary.*

Well, interesting. During my days as a hang glider pilot, I designed, built, and lost many 'sacrificial victims to the wind gods'.

Fixed wing systems will always be more efficient and way less complex to build and maintain. Rotor based drones like quadcopers will always have a higher maneuverability, can easily set on a stable hovering position and are also much less complex. Both systems can also be upscaled much more easy then flex winged designs. Beside being cool, their main advantage is the ability to blend into the natural environment very easily and convincingly.

It's my understanding that rotating wheels, or propellers have not evolved in nature because of the bloodflow problem. If a propeller spins freely, separate from the body of the animal, then how do you get blood through that rotating joint?

On a hovering bird vs a hovering drone, i'm not really sure, but as stated above, the advantage of a constantly rotating wing (propeller blade) is that you don't need to change angle or speed within the cycle. They are both wings, one is simple in constant motion, while the other needs to stop and start, and changes direction through sub-optimal angles of attach, and fight the momentum of the wing itself. if you want to argue further, lets hold it to a comparison of a constant speed wing, vs a changing speed wing. my point is also only about efficiency, not about agility or flexibility. You can get increased flexibility with rotating wings/propellors, but at the cost of needing to moderate either the blade pitch, or speed of a fixed pitch propeller.

@@CosmicHamster Yes, there are too many stories and paintings and carvings of dragons for them all to be imaginary. Some of them look just like dinosaurs, oddly enough.

Dragons were real and demons still are. Though the depictions of both are symbolic, not accurate.

Ok, this is coolest thing I’ve seen in like 30 years.

Amazing video! I love these robot birds! Also I recently learned that bats have a higher flight speed than most birds, so that could be a good reason to focus on bat flight mechanics over others.

Psssss! You shouldn't reveal HOW birds aren't real. It's supposed to be a secret.

Humans aren’t smart enough to invent nature, just repurpose its designs.

I remember doing a little bit of undergrad research on the aerodynamic characteristics of wings with flexible membranes, like the bat wings Pretty interesting

I had the Flytech flying dragonfly model from WowWee. It had a steep learning curve, but one thing I noticed was that every time I took it outside, the birds would attack it....even though it was bigger than most of the birds around.....

So birds aren't real after all?

Neither are people. . .experimental for sure.

This is truly amazing.❤

When I was around 10, I got a gift of a wind-up plastic bird this was about 1977. It was made in France had thick round rubber band for power and an extremely simple mechanism. The wings were one plastic beam on the leading edge and a mylar airfoil with a L -x- W ratio of approximately 2.8. The membrane was not taught, but had slack on the trailing edge, with one rearward attachment point 2/3 of the way out from the body. I don't remember the company or product name, but I believe it's been around for quite some time. When fully wound it would fly for a surprising amount of time, maybe 30 seconds. Quite controllable flight pattern and elevation control because of a ball joint mounted tail of similar design. It would fly perfectly at altitude and moderate speed in circles of any diameter or straight depending on tail pitch and yaw.

Yeah, I've been researching the topic of ornitopters a few years back. Turns out for now propellers are almost always the most effective (and have less moving parts). The biggest flying (dinosaur, probably only gliding tho) animal could weigh as much as 250 kg! - right now the biggest is albatros I think. Theoretically.. if you could build something that weighs roughly 170kg.. add a human.. and you're riding a dragon my friend. I was planning to get back to the idea when we'll have sum more progress in technology. Especially lighter materials with the same or bigger strength

Can't wait to go see it.

It's off putting how chill this guy is over more surveillance. Off putting indeed.

Well done Ziroth! By trying to copy nature we re only more amazed about what nature is able to do! You addressed the issue of running-time. 3 hours max. Again: nature is still sooo much better. Amazing, no?

I hope that he had talked about the bionic wings during the video. However, if had helped a lot on my project and keep up the good work!

00:00 🛸 Drones today have limitations, spurring interest in bionic wings for enhanced maneuverability and efficiency. 01:21 🦅 Real birds' wing movements - folding, twisting, bending - inspire bionic drone designs, enabling energy efficiency and versatile flight control. 02:30 🦇 Bats' flight, resembling swimming, influences drone wings; long fingers and wing control offer exceptional maneuverability. 03:55 🚁 Bionic drone assembly involves converting motor rotation into wing flapping motion for flight; initial test flights exhibit agility and directional changes. 05:47 🦇 Bionic flying fox by Festo showcases lightweight, flexible wings, improving performance through motion capture and machine learning for autonomous flight. 07:09 🌐 Nano air vehicles, like the hummingbird-inspired drone, demonstrate intricate flight capabilities for surveillance and research, with ongoing efforts to enhance stability and silence. 08:57 🛠 Research focuses on wing angle optimization and joint elasticity to boost efficiency, stability, and payload capacity in bionic drones. 09:53 🐦 Bionic Swift's design mimics bird plumage for superior energy efficiency, precise flight control, and coordinated swarm behavior via GPS and communication technology. 10:49 🕊 Bionic birds demonstrate increasing flight durations, showcasing potential advancements in drone technology, especially when combined with AI for autonomous flight correction. 11:29 🔬 Bionic wings hold promise for future drone development, with military interest and ongoing advancements in maneuverability and flight capabilities.

I think it would be much easier and more efficient to make sturdy wings like a plane and just use the propeller at the front. And upgraded version of this could be a VTOL mechanic like MV-22 Osprey or something but perhaps with only one propeller.

I'm surprised insects were not mentioned. The epitome of flight is the dragonfly. Which is why it has the highest hunting success rate of 95%.

agreed: the dragonfly is so cool, it gives me goosebumps

When I was a kid in the 1960s, my dad had a friend who brought one of these over to our house. It was made from wire and the wings were cloth. It had a windup spring that flapped the wings. He flew it around in our backyard. He was planning to turn it into a toy product, which he eventually did. The resulting product had thin plastic colorful wings. I think it was manufactured by Whamo, but I don't recall the product name.

Thanks Tom! Great work!

0:33 "...I'll be flying the bionic drone that I brought." I'm so glad you didn't leave it in the store.

wow this is amazing infomation!!!

Probably due to lack of publishing, Hobbyists have made similar advancements but are not recognized for doing so. Mat Keenon is the pilot seen flying the hummingbird. He usually used UHF transmitters and receivers before 2.4 GHz became readily available.

Da Vinci made one of these. Really insane seeing these become remote controlled. I had a rubber band powered one as a kid.

If the percentage of energy efficiency was also mentioned in the video that would have been great. I think this would be more useful only in surveillance scenarios and definitely would give an entry into toy market.

Very good video. I got lots to learn.

To get more lift maybe there could be wings based on pterosaurs, which catapulted themselves into the air using all 4 limbs, which is what allowed them to grow so big

imagine a springpole to the fulcrum of a massive elastic wingspan, jump wings! (standing on a platform, a backpack mounts the wingspan behind you)

Whoever had the idea to add a splash sound to the eagle clip is a genius

In the future, it would be interesting to see this technology applied to ultralights.

Oh my god.. imagine a military drone that uses this technology but uses the quetzalcoatlus as a base for the design.. terrifying..

Hey Ziroth, great video on this one. Where can I get the drone you used in it? Thanks!

The next thousand years of aero design - from planes, drones and maybe even human flight packs is going to be very interesting.

This is fantastic and really useful for when actual birds go extinct through our relentless technological innovation. Bravo humans.

Very interesting, thank you for sharing. I have question, which kit and from where did you buy it?

I love the 1800s wing flapping machines , they were hilarious,, were seemingly going full circle.

Btw the compressive force of the air under a wing is nowhere near as important in generating lift as the decreased pressure above the wing. Both have an effect on the total lift, but the "vacuum" effect above the wing is much more significant (80% of lift occurs due to the forces on the top surface of an aerofoil)

It's unbelievable how technology is developing so rapidly

I swam competitively and taught it as well. Drones remind me of the ‘egg beater’ way of treading water, where it works, but it’s incredibly energy inefficient. The way you should tread water is by doing whip kick and using your arms to push water down. Your arms act as both a way of stabilizing as well as a way to supplement your kicks. A single high power ‘tread’ when doing it with whip kick propels you far more than the constant, low power egg beater and is far more energy efficient while being much easier to maneuver with.

*Mating in mid-air will be the next huge tourist attraction!*

Very interesting I have always asked myself what makes the birds fly long distance without any up and down of their wings Infact what proell them forward motions when their wings at rest in stretched position

This is GREAT! When will we be reinventing ultralight aircraft?

This is so cool. We're getting our 10th real life depiction of a black mirror episode this year 😅

Dear autor you are so cool, i cant stop watching your channel!

Can wait for a backpack with them wings to fly individually
