A robot that flies like a bird | Markus Fischer

Prevodilac: Natasa Golosin Lektor: Ana Zivanovic-Nenadovic

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

San ljudske rase

je da leti kao ptica.

Birds are very agile.

Ptice su veoma pokretne.

They fly, not with rotating components,

Lete bez komponenti koje rotiraju,

so they fly only by flapping their wings.

samo mašući krilima.

Posmatrali smo ptice,

So we looked at the birds,

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

i pokušali da napravimo model

koji je snažan, a veoma lak,

and it must have excellent aerodynamic qualities

i vrlo aerodinamičan

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

koji bi leteo sam od sebe

samo mašući krilima.

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

Dakle, šta bi bilo bolje kao model

nego galeb,

circling and swooping over the sea,

koji slobodno leti nad morem

and to use this as a role model?

i u njega zaranja?

So we bring a team together.

Okupili smo tim.

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

Šire i uže specijalizovanih stručnjaka

u oblasti aerodinamike

in the field of building gliders.

i izgradnje jedrilica.

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

I zadatak je bio da se napravi

vrlo lak, leteći model za unutrašnji prostor

that is able to fly over your heads.

koji može da leti iznad nas.

Tako da, budite oprezni kasnije.

So be careful later on.

(Laughter)

Zadatak je bio

And this was one issue:

to build it that lightweight

napraviti ga veoma lakog

that no one would be hurt if it fell down.

kako niko ne bi bio povređen

ukoliko se sruši.

So why do we do all this?

Dakle, zašto radimo sve ovo?

We are a company in the field of automation,

Mi smo kompanija koja se bavi automatikom,

and we'd like to do very lightweight structures

i voleli bismo da pravimo lake strukture

because that's energy efficient,

zbog uštede energije.

I voleli bismo da naučimo više o

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

pneumaticima i fenomenu protoka vazduha,

Sada bih voleo da

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

se vežete

and put your hats on.

i stavite svoje kape.

So maybe we'll try it once --

Pa da pokušamo

to fly a SmartBird.

da poletimo SmartBirdom.

Thank you.

Hvala.

(Applause)

(Aplauz)

(Cheers)

(Aplauz)

(Applause)

(Applause ends)

(Applause)

(Aplauz)

So we can now look at the SmartBird.

Sada možemo

pogledati SmartBird.

Ovde je jedna bez kože.

So here is one without a skin.

We have a wingspan of about two meters.

Raspon krila je oko dva metra.

The length is one meter and six,

Dužina metar i šezdeset.

and the weight is only 450 grams.

težina je

samo 450 grama.

And it is all out of carbon fiber.

I cela je od karbonskih vlakana.

In the middle we have a motor,

U sredini je motor,

and we also have a gear in it,

koji ima menjač.

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

Menjač koristimo

za prenos cirkulacije motora.

So within the motor, we have three Hall sensors,

U motoru imamo tri "Hol" senzore,

tako da tačno znamo gde

so we know exactly where the wing is.

je krilo.

And if we now beat up and down --

I ako sad mašemo gore dole

(Mechanical sounds)

We have the possibility to fly like a bird.

možemo

da letimo kao ptica.

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

Tako da, ako idete dole, imate veliku površinu za pogon.

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 podići se.

Naredna stvar koju smo napravili,

So, the next thing we did,

ili, naredni izazov koji smo prihvatili,

or the challenges we did,

was to coordinate this movement.

bilo je da koordiniramo ove pokrete.

Moramo da je okrenemo, idemo gore i dole.

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

Imamo podeljeno krilo.

We have a split wing.

With the split wing,

Njime

we get the lift at the upper wing,

stvaramo pritisak na gornjem krilu,

and we get the propulsion at the lower wing.

i imamo pogon na donjem krilu.

Also, we see how we measure the aerodynamic efficiency.

Takođe, možemo da vidimo

kako da izmerimo aerodinamičnu efikasnost.

We had knowledge about the electromechanical efficiency

Znali smo za

aerodinamičnu efikasnost

and then we can calculate the aerodynamic efficiency.

i mogli smo da je

izračunamo.

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

Dakle,

penje se od pasivne ka aktivnoj torziji,

od 30 odsto

from 30 percent up to 80 percent.

do 80 odsto.

Next thing we have to do,

Sledeća stvar koju moramo da uradimo

we have to control and regulate the whole structure.

kako bismo kontrolisali i regulisali

celu strukturu.

Only if you control and regulate it,

Samo ukoliko je kontrolišete i regulišete,

you will get that aerodynamic efficiency.

postići ćete aerodinamičnu efikasnost.

So the overall consumption of energy

Tako je ukupna potrošnja energije

is about 25 watts at takeoff

oko 25 vati pri uzletanju

and 16 to 18 watts in flight.

i od 16 do 18 vati u toku leta.

Hvala.

Thank you.

(Applause)

(Aplauz)

Bruno Đusani: Markus, mislim da bi trebalo da to ponovimo.

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

Markus Fischer: Yeah, sure.

Markus Fišer: Da, sigurno.

(Audience) Yeah!

(Smeh)

(Laughter)

(Gasps)

(Uzdasi)

(Cheers)

(Ovacije)

(Applause)
