A robot that flies like a bird | Markus Fischer

It is a dream of mankind to fly like a bird.

San je čovječanstva

letjeti poput ptice.

Birds are very agile.

Ptice su veoma pokretne.

They fly, not with rotating components,

One lete, bez rotirajućih komponenti,

so they fly only by flapping their wings.

dakle, one lete samo mlatareći svojim krilima.

Stoga smo promatrali ptice

So we looked at the birds,

and we tried to make a model that is powerful, ultralight,

i pokušali smo napraviti model

koji je moćno lagan,

and it must have excellent aerodynamic qualities

i mora imati izvrsne aerodinamičke kvalitete

that would fly by its own and only by flapping its wings.

koji bi mu omogućile da leti samostojno

i samo mlatareći krilima.

So what would be better than to use the herring gull, in its freedom,

A što bi bilo bolje nego koristiti

Herringovog galeba, u svoj svojoj slobodi,

circling and swooping over the sea,

kako kruži i nalijeće nad morem,

and to use this as a role model?

i koristiti ga kao uzor?

So we bring a team together.

Stoga smo okupili tim.

There are generalists and also specialists in the field of aerodynamics,

Postoje generalisti i ujedno i stručnjaci

na polju aerodinamike

in the field of building gliders.

na polju izgradnje jedrilica.

And the task was to build an ultralight indoor-flying model

A zadatak je bio izraditi

ultralagan unutarnji leteći model

that is able to fly over your heads.

koji može letjeti iznad vaših glava.

Stoga se pripazite kasnije.

So be careful later on.

(Laughter)

A ovo je bio jedan izazov:

And this was one issue:

to build it that lightweight

izraditi ga tako laganim

that no one would be hurt if it fell down.

da se nitko ne bi ozlijedio

kada bi pao dolje.

So why do we do all this?

Zašto onda radimo to sve?

We are a company in the field of automation,

Mi smo kompanija koja djeluje na polju automatizacije,

and we'd like to do very lightweight structures

i mi volimo izrađivati vrlo lagane strukture

because that's energy efficient,

jer su one energetski učinkovite.

I voljeli bismo naučiti više o

and we'd like to learn more about pneumatics and air flow phenomena.

pneumatici i fenomenu protoka zraka.

Stoga bih želio da sada

So I now would like you to put your seat belts on

vežete svoje pojaseve

and put your hats on.

i stavite na glavu svoje kape.

So maybe we'll try it once --

Možda ćemo pokušati jednom

to fly a SmartBird.

letjeti SmartBirdom.

Thank you.

Hvala vam.

(Applause)

(Pljesak)

(Cheers)

(Pljesak)

(Applause)

(Applause ends)

(Applause)

(Pljesak)

So we can now look at the SmartBird.

Stoga možemo sada

promotriti SmartBird.

Ovdje je jedna bez kože.

So here is one without a skin.

We have a wingspan of about two meters.

Imamo promjer krila od oko dva metra.

The length is one meter and six,

Dužina je metar šezdeset,

and the weight is only 450 grams.

a težina,

je oko samo 450 grama.

And it is all out of carbon fiber.

I cijela je od karbonskih vlakana.

In the middle we have a motor,

U sredini imamo motor,

and we also have a gear in it,

i imamo i mjenjač u njoj.

and we use the gear to transfer the circulation of the motor.

I koristimo taj mjenjač

kako bi prenijeli cirkulaciju motora.

So within the motor, we have three Hall sensors,

Dakle, unutar motora, imamo tri Hall senzora,

kako bi znali točno gdje

so we know exactly where the wing is.

je krilo.

And if we now beat up and down --

I ako sada mlataramo gore dolje...

(Mechanical sounds)

We have the possibility to fly like a bird.

imamo mogućnost

letjeti poput ptice.

So if you go down, you have the large area of propulsion,

Dakle, ako idete dolje, imate veliko područje uzgona.

A ako idete gore,

and if you go up,

krila nisu toliko velika,

the wings are not that large,

and it is easier to get up.

i lakše je ići gore.

Dakle, iduća stvar koju smo napravili,

So, the next thing we did,

ili izazove koje smo premostili

or the challenges we did,

was to coordinate this movement.

su bili koordinacija tog kretanja.

Moramo je okrenuti, ići gore i ići dolje.

We have to turn it, go up and go down.

Imamo potrgano krilo.

We have a split wing.

With the split wing,

S potrganim krilom

we get the lift at the upper wing,

dobijemo potisak na gornjem krilu,

and we get the propulsion at the lower wing.

i dobijemo uzgon na donjem krilu.

Also, we see how we measure the aerodynamic efficiency.

Ujedno, vidimo

kako mjerimo učinkovitost aerodinamike.

We had knowledge about the electromechanical efficiency

Imali smo znanje o

elektromehaničkoj učinkovitosti

and then we can calculate the aerodynamic efficiency.

i zatim možemo izračunati

aerodinamičku učinkovitost.

So therefore, it rises up from passive torsion to active torsion,

Stoga,

podiže se iz pasivne torzije u aktivnu torziju,

s 30 posto

from 30 percent up to 80 percent.

na 80 posto.

Next thing we have to do,

Iduća stvar koju moramo učiniti,

we have to control and regulate the whole structure.

je kotroliranja i reguliranje

cijele strukture.

Only if you control and regulate it,

Samo ako je kontrolirate i regulirate,

you will get that aerodynamic efficiency.

dobiti ćete aerodinamičku učinkovitost.

So the overall consumption of energy

Dakle, ukupna potrošnja energije

is about 25 watts at takeoff

je oko 25 vati prilikom polijetanja

and 16 to 18 watts in flight.

i 16 do 18 vati u letu.

Hvala vam.

Thank you.

(Applause)

(Pljesak)

Bruno Giussani: Markus, mislim kako bi trebala još jednom letjeti.

Bruno Giussani: Markus, we should fly it once more.

Markus Fischer: Yeah, sure.

Markus Fischer: Da, naravno.

(Audience) Yeah!

(Smijeh)

(Laughter)

(Gasps)

(Uzdasi)

(Cheers)

(Navijanje)

(Applause)
