Abstract-Flapping wing robots show promise as platforms for safe and efficient flight in near-human operations, thanks to their ability to agile maneuver or perch at a low Reynolds number. The growing trend in the automatization of these robots has to go hand in hand with an increase in the payload capacity. This work provides a new passive morphing wing prototype to increase the payload of this type of UAV. The prototype is based on a biased elastic joint and the holistic research also includes the modelling, simulation and optimization scheme, thus allowing to adapt the prototype for any flapping wing robot. This model has been validated through flight experiments on the available platform, and it has also been demonstrated that the morphing prototype can increase the lift of the robot under study by up to 16% in real flight while consumption is reduced by 10%.

Theme parks would go crazy for flying dragons, phoenixes, pterosaurs, etc. Imagine Harry Potter world or Jurassic World in Universal studios, or something in Disney.
Thank you for sharing, i like it. Good job 👍🏻
Good job
Planes of the near future. Cool.
very cool
There is an interesting design of aircraft, but they rarely talk about it, because this thing is secret. The topic of pulsed plasma thrusters has been developed since the early 60s (see PPT - Pulsed plasma thruster) - they are usually designed for spacecraft. But we will talk about a little-known design - these are plasma propulsion panels for aircraft, where the same Pulsed plasma thruster, but reduced to the size of a pencil and stacked in the form of cells in the panel. The design resembles a conventional plasma TV screen, where there are also discharge cells that activate the glow of pixels on the screen. And plasma propulsion panels have long discharge cells, the arrester has a railgun architecture (just rail contacts or coaxial), and the ionized discharge air is accelerated there by the Lorentz force to enormous speeds - a kind of ramjet engine is obtained. Just imagine! - tens of thousands of small ramjet engines assembled in a panel and firing plasma synchronously with a huge frequency (hundreds of kilohertz). Thus, plasma propulsion panels create lift by pulsed emission of plasma jets from railgun cells. There are tens of thousands of cells in the panel, they shoot at a frequency of hundreds of kilohertz, a huge pulse is obtained, and the plasma swirls the air into toroidal rings - the aircraft is held on this air cushion. Horizontal acceleration is created by the same plasma panels on the sides of the device (they glow, from the side they look like "portholes"). Such devices like "triangle" or "disk" have been observed for a long time, they are mistaken for alien ones - but these are terrestrial devices. They are classified and used for espionage and secret actions. Pulsed electromagnetic technology generates microwave radiation, therefore it is harmful to health. They rarely fly - only military missions. Therefore, they are not suitable for a citizen. This maintained the secrecy. Now they are already declassifying - many people know about this secret technique. When declassified, they will be used for cargo airships. But there is a danger that they are now going to be adapted to deliver small nuclear charges to decision-making centers - such means of delivery are not specified anywhere, are not conventional. This lowers the threshold for starting a war. It would be necessary to declassify them as soon as possible. That's why I'm writing about it.
I shall become BAT Drone !!
And i belive i can fl- IT FLQPS SLOW IM FALLIN
U DO GJ
This is great. May be combine this with balloon body or just rotors drone for some lift and you got a product !
Cant wait for the hummingbird motor…
should've made it with feathers if you're going for that form where the wings just flap. if you were going to go for the bat-like wings, you need to have the wings pull into the body because when the wings don't pull back into the body on the way up they encounter the air above it and that causes the wings to catch the air and push the vehicle downwards. bird feathers allow air to move between them on the way up so they don't have a downward force exerted on them when the wings go up. bats have to pull their wings in in order to not have a downward force on them aside from gravity.
"You need to learn to crawl before you can walk". Making feathers that work in wings is not a simple task. I think they know what they are doing
Looks like a blue heron flying
hey very cool - is that joint several compliant mechanisms?
Greetings,
Thank you for your comment. It is a single compliant mechanism with a spring.
Can you make a larger one to carry someone like me?
❤❤🎉 fly brid😮🐦
Let me know when you get a human mounted set of wings for 150lbs. I'd die to be a test pilot. ;)
How does efficiency compare to a quad copter of the same weight?
Greetings,
These bio-inspired robots are more efficient than a quadcopter for traveling long distances.

What is the actual purpose of pouring money into research like this, i mean, in the end, is there, other than ammusement, a practical aplication for one of these machines? We still can't make a machine that consistantly lightly burns bread to an acceptible degree. Where and when is there gonna be a use for these things that will result in sales that will recoup the millions spent in the R&D?
Greetings,
These bio-inspired robots are designed to interact with the environment in the least invasive and energy-efficient way possible. They can be used to perform a variety of tasks, such as taking samples in natural environments or inspecting pipes, power lines and other structures.
@@GRVCRoboticsLaboratory , Innovation is great, but there's already a multitude of Drones with proven flight capabilities that are fully capable of doing the tasks you listed.
@@toter-drache Greetings again,
Bio-inspired robots can interact more safely with the environment and people because they are not rotor-like. The purpose of such robots is not only this, but also to be more energy efficient and less disruptive to natural environments.
Why?
Exactly, "Why?"
Вот это и все достижения в этой области, всё остальное- кино!
Сказки о "летающих" насекомых в американской армии и тому подобные бред для выкачивания бабла из лохов:" Нет у вас приёмов против Кости Сапрыкина!"
This is true. Ornithopters are always expensive, over-engineered, and fragile especially compared to quadcopters
