A robot that flies like a bird | Markus Fischer

August 25, 2019

It is a dream of mankind
to fly like a bird. Birds are very agile. They fly, not with rotating components, so they fly only by flapping their wings. So we looked at the birds, and we tried to make a model
that is powerful, ultralight, and it must have excellent
aerodynamic qualities that would fly by its own
and only by flapping its wings. So what would be better than to use
the herring gull, in its freedom, circling and swooping over the sea, and to use this as a role model? So we bring a team together. There are generalists and also specialists
in the field of aerodynamics, in the field of building gliders. And the task was to build
an ultralight indoor-flying model that is able to fly over your heads. So be careful later on. (Laughter) And this was one issue: to build it that lightweight that no one would be hurt if it fell down. So why do we do all this? We are a company
in the field of automation, and we’d like to do
very lightweight structures because that’s energy efficient, and we’d like to learn more
about pneumatics and air flow phenomena. So I now would like you
to put your seat belts on and put your hats on. So maybe we’ll try it once — to fly a SmartBird. Thank you. (Applause) (Cheers) (Applause) (Applause ends) (Applause) So we can now look at the SmartBird. So here is one without a skin. We have a wingspan of about two meters. The length is one meter and six, and the weight is only 450 grams. And it is all out of carbon fiber. In the middle we have a motor, and we also have a gear in it, and we use the gear
to transfer the circulation of the motor. So within the motor,
we have three Hall sensors, so we know exactly where the wing is. And if we now beat up and down — (Mechanical sounds) We have the possibility
to fly like a bird. So if you go down, you have
the large area of propulsion, and if you go up, the wings are not that large, and it is easier to get up. So, the next thing we did, or the challenges we did, was to coordinate this movement. We have to turn it, go up and go down. We have a split wing. With the split wing, we get the lift at the upper wing, and we get the propulsion
at the lower wing. Also, we see how we measure
the aerodynamic efficiency. We had knowledge
about the electromechanical efficiency and then we can calculate
the aerodynamic efficiency. So therefore, it rises up
from passive torsion to active torsion, from 30 percent up to 80 percent. Next thing we have to do, we have to control and regulate
the whole structure. Only if you control and regulate it, you will get that aerodynamic efficiency. So the overall consumption of energy is about 25 watts at takeoff and 16 to 18 watts in flight. Thank you. (Applause) Bruno Giussani: Markus,
we should fly it once more. Markus Fischer: Yeah, sure. (Audience) Yeah! (Laughter) (Gasps) (Cheers) (Applause)

  1. imaginge how this can be used to spy and survailence. make it smaller, like a crow and take real feaders from a dead crow. then put a camera in the head looking like eyeballs.

  3. As a Pilot, I think this is a revelation in flight dynamics and is a beautiful inspiration to making flight dreams real. well done all of you involved in the project!

  4. "Plenty of robots can fly — but none can fly like a real bird." I guess @TED wasn't aware of Sean Kinkade's SubBird and ParkHawk ornithopters which have been flying around since at least 2004. Vale, Sean.

  5. 6 years ago and that was far less advanced than the military has, far less, esoecially in guidance and computar function, camera ability and weaponization..WHAT exists today is more than the difference between a model T and a ALMOST modern car.

  6. I want wings kind of like this that I can wear and train to use so I can fly. If this bird is possible then that has to be too.

  7. A passion of humanity come true. I applaud the engineering team and their tenacity to pay attention to detail.

  8. the number or person you are trying to reach is not in service and does not exist if this is an emergecy please hung up, pray, and try your call again later..

  9. Yea, well one if thise but smaller and faster just flew over my house. So don't be angry when i blow it out of the sky and reprogram it

  10. That's awesome you know what else would be awesome if the bird landed on your shoulder so you can have a buddy on your shoulder and if you made the wings on your back so you can fly.

  11. presumably the've spent ages and millions developing it but wait till a china man gets a hand in one of this, they'll be selling cheap copies on eBay for $5 ha ha

  12. If 2 meter wide wing can fly 450 gram of weight, then to fly a human about 45 kg need 200 meter wide wing. That's three times size of average airplane wings!

  13. Ronnie Dobbs Britton make one big enough for humans to fly on it would be a fun ride but make it smart and intelligent can talk that way you can tell him where you want to go and it will take you no problems

  14. It's good we are starting to build robotic animals: with this pace soon there will be no more alive species rather than humans and cockroaches. 🙁

  15. Men always look like childs) they are stand up and applause for smart bird every time when it is fly))

  16. People have been building model ornithopters since the 1920's at least. You can buy a radio controlled toy ornithopter. If it flies like a bird, why can't it take of and land? I look forward tp you inventing the wheel.

  17. make it bigger and stronger, than human go into this and Flying,,,,,,, Wow it,s a dream.

  18. 05:27 "Markus, I feel, we should fly it once more". Kudos to that person asking to fly one more time.

  19. So now we will travel around the world in a Bird (next generation aeroplane, of course)…. 😍😍

  20. It's great that we can replace real birds that are going extinct 🤨
    We are applauding this as if it's important. Humans should be very very afraid of this phenomena: mimicking real things at the cost of the environment that allows organisms to exist.
    But that's fine, right? Because now we have fully controllable, synthetic versions.

  21. 10/24 tenth video!
    I saw some birl like robot before, but I think this one would be the best. I'm bit sad that this video is too short. I think the robot company such as boston dynamics and festo, they are really curious about nature. They both design their robot similar with bug or animals, because their design is very light and efficient. Imitating nature leads engineers to make better robot. Good

  22. Yawn, this just flies like a typical ornithopter, a typical grade school science project, but with an extra joint in the wings. This uses up and down flapping motion, real birds flap their wings in an elliptical pattern, like a swimmer performing the breast stroke.

  23. Reading some of these comments makes me cringe. Bad grammar aside, I sincerely hope that mankind's intelligence is not on par with some of the discourse presented below.
