    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.

This is great. May be combine this with balloon body or just rotors drone for some lift and you got a product !

hey very cool - is that joint several compliant mechanisms?

Greetings, Thank you for your comment. It is a single compliant mechanism with a spring.

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?

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

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.

@@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.

This is true. Ornithopters are always expensive, over-engineered, and fragile especially compared to quadcopters
