ABOUT THE SPEAKER
Markus Fischer - Designer
Markus Fischer led the team at Festo that developed the first ultralight artificial bird capable of flying like a real bird.

Why you should listen

One of the oldest dreams of mankind is to fly like a bird. Many, from Leonardo da Vinci to contemporary research teams, tried to crack the "code" for the flight of birds, unsuccessfully. Until in 2011 the engineers of the Bionic Learning Network established by Festo, a German technology company, developed a flight model of an artificial bird that's capable of taking off and rising in the air by means of its flapping wings alone. It's called SmartBird. Markus Fischer is Festo's head of corporate design, where he's responsible for a wide array of initiatives. He established the Bionic Learning Network in 2006.

SmartBird is inspired by the herring gull. The wings not only beat up and down but twist like those of a real bird -- and seeing it fly leaves no doubt: it's a perfect technical imitation of the natural model, just bigger. (Even birds think so.) Its wingspan is almost two meters, while its carbon-fiber structure weighs only 450 grams.

Fischer says: "We learned from the birds how to move the wings, but also the need to be very energy efficient."

Mnoštvo robota može letjeti -- ali nijedan ne može letjeti poput prave ptice. To jest, sve dok Markus Fischer i njegov tim u Festo-u nisu izradili SmartBird, veliki, lagani robot, koji je modeliran po uzoru na galeba, koji leti mlatareći krilima. Uzvišeno svježa demostracija iz TEDGlobala 2011.

Ptice su veoma pokretne.
00:22
They flyletjeti, not with rotatingrotirajući componentskomponente,
3

3000
One lete, bez rotirajućih komponenti,
00:25
so they flyletjeti only by flappingsklapanja theirnjihov wingskrila.
4
10000
3000
dakle, one lete samo mlatareći svojim krilima.
00:28
So we lookedgledao at the birdsptice,
5
13000
3000
Stoga smo promatrali ptice
00:31
and we triedpokušala to make a modelmodel
6
16000
3000
i pokušali smo napraviti model
00:34
that is powerfulsnažan, ultralightUltra laka letilica,

koji je moćno lagan,
00:37
and it mustmora have excellentodličan aerodynamicaerodinamičan qualitiesosobine

00:43
and only by flappingsklapanja its wingskrila.
10
28000
3000
i samo mlatareći krilima.
00:46
So what would be better [than] to use
11
31000
3000
A što bi bilo bolje nego koristiti

00:56
So we bringdonijeti a teamtim togetherzajedno.

Stoga smo okupili tim.

There are generalistsgeneralists and alsotakođer specialistsstručnjaci

01:06
And the taskzadatak was to buildizgraditi

01:14
So be carefulpažljiv laterkasnije on.
22
59000
3000
Stoga se pripazite kasnije.
01:19
And this was one issueizdanje:
23
64000
2000
A ovo je bio jedan izazov:
01:21
to buildizgraditi it that lightweightlak
24
66000
2000
izraditi ga tako laganim
01:23
that no one would be hurtpovrijediti
25
68000
2000
da se nitko ne bi ozlijedio
01:25
if it fellpao down.
26
70000
3000
kada bi pao dolje.
01:28
So why do we do all this?
27
73000
2000
Zašto onda radimo to sve?
01:30
We are a companydruštvo in the fieldpolje of automationAutomatizacija,
28
75000
3000
Mi smo kompanija koja djeluje na polju automatizacije,
01:33
and we'dmi bismo like to do very lightweightlak structuresstrukture
29
78000
3000
i mi volimo izrađivati vrlo lagane strukture
01:36
because that's energyenergija efficientučinkovit,
30
81000
2000
jer su one energetski učinkovite.
01:38
and we'dmi bismo like to learnnaučiti more about
31
83000
3000
I voljeli bismo naučiti više o
01:41
pneumaticspneumatici and airzrak flowteći phenomenapojave.
32
86000
3000
pneumatici i fenomenu protoka zraka.
01:44
So I now would like you
33
89000
3000
Stoga bih želio da sada
01:47
to [put] your seatsjedalo beltsremenje on
34
92000
2000
vežete svoje pojaseve
01:49
and put your hatskape [on].
35
94000
2000
i stavite na glavu svoje kape.
01:51
So maybe we'lldobro try it oncejednom --
36
96000
3000
Možda ćemo pokušati jednom
01:54
to flyletjeti a SmartBirdSmartBird.
37
99000
2000
letjeti SmartBirdom.
01:56
Thank you.
38

2000
Hvala vam.

(Pljesak)
02:52
(ApplausePljesak)
41
157000
15000
(Pljesak)
03:07
So we can now
42
172000
2000
Stoga možemo sada
03:09
look at the SmartBirdSmartBird.
43
174000
3000
promotriti SmartBird.
03:12
So here is one withoutbez a skinkoža.
44
177000
3000
Ovdje je jedna bez kože.
03:15
We have a wingspanraspon krila of about two metersmetara.
45
180000
3000
Imamo promjer krila od oko dva metra.
03:18
The lengthdužina is one metermetar and sixšest,
46
183000
3000
Dužina je metar šezdeset,
03:21
and the weighttežina,
47
186000
2000
a težina,
03:23
it is only 450 gramsgrama.
48
188000
3000
je oko samo 450 grama.
03:26
And it is all out of carbonugljen fibervlakno.
49
191000
3000
I cijela je od karbonskih vlakana.
03:29
In the middlesrednji we have a motormotor,
50
194000
2000
U sredini imamo motor,
03:31
and we alsotakođer have a gearzupčanik in it,
51
196000
4000
i imamo i mjenjač u njoj.
03:35
and we use the gearzupčanik
52
200000
2000
I koristimo taj mjenjač
03:37
to transferprijenos the circulationCirkulacija of the motormotor.
53
202000
3000
kako bi prenijeli cirkulaciju motora.
03:40
So withinunutar the motormotor, we have threetri HallDvorana sensorssenzori,
54
205000
3000
Dakle, unutar motora, imamo tri Hall senzora,
03:43
so we know exactlytočno where
55
208000
3000
kako bi znali točno gdje
03:46
the wingkrilo is.
56
211000
3000
je krilo.
03:49
And if we now beatpobijediti up and down ...
57
214000
3000
I ako sada mlataramo gore dolje...
03:56
we have the possibilitymogućnost
58
221000
2000
imamo mogućnost
03:58
to flyletjeti like a birdptica.
59
223000
2000
letjeti poput ptice.
04:00
So if you go down, you have the largeveliki areapodručje of propulsionpogon,
60
225000
3000
Dakle, ako idete dolje, imate veliko područje uzgona.
04:03
and if you go up,
61
228000
3000
A ako idete gore,
04:06
the wingskrila are not that largeveliki,
62
231000
4000
krila nisu toliko velika,
04:10
and it is easierlakše to get up.
63
235000
3000
i lakše je ići gore.
04:14
So, the nextSljedeći thing we did,
64
239000
3000
Dakle, iduća stvar koju smo napravili,
04:17
or the challengesizazovi we did,
65
242000
2000
ili izazove koje smo premostili
04:19
was to coordinatekoordinirati this movementpokret.
66
244000
3000
su bili koordinacija tog kretanja.
04:22
We have to turnskretanje it, go up and go down.
67
247000
3000
Moramo je okrenuti, ići gore i ići dolje.
04:25
We have a splitSplit wingkrilo.
68
250000
2000
Imamo potrgano krilo.
04:27
With a splitSplit wingkrilo
69
252000
2000
S potrganim krilom
04:29
we get the liftlift at the upperGornji wingkrilo,
70
254000
3000
dobijemo potisak na gornjem krilu,
04:32
and we get the propulsionpogon at the lowerdonji wingkrilo.
71
257000
3000
i dobijemo uzgon na donjem krilu.
04:35
AlsoTakođer, we see
72
260000
2000
Ujedno, vidimo
04:37
how we measuremjera the aerodynamicaerodinamičan efficiencyefikasnost.
73
262000
3000
kako mjerimo učinkovitost aerodinamike.
04:40
We had knowledgeznanje about
74
265000
2000
Imali smo znanje o
04:42
the electromechanicalelektromehanička efficiencyefikasnost
75
267000
2000
elektromehaničkoj učinkovitosti
04:44
and then we can calculateizračunati
76
269000
2000
i zatim možemo izračunati
04:46
the aerodynamicaerodinamičan efficiencyefikasnost.
77
271000
2000
aerodinamičku učinkovitost.
04:48
So thereforestoga,
78
273000
2000
Stoga,
04:50
it risesdiže up from passivepasivan torsiontorzijska to activeaktivan torsiontorzijska,
79
275000
3000
podiže se iz pasivne torzije u aktivnu torziju,
04:53
from 30 percentposto
80
278000
2000
s 30 posto
04:55
up to 80 percentposto.
81
280000
2000
na 80 posto.
04:57
NextSljedeći thing we have to do,
82
282000
2000
Iduća stvar koju moramo učiniti,
04:59
we have to controlkontrolirati and regulateregulirati
83
284000
2000
je kotroliranja i reguliranje
05:01
the wholečitav structurestruktura.
84
286000
2000
cijele strukture.
05:03
Only if you controlkontrolirati and regulateregulirati it,
85
288000
3000
Samo ako je kontrolirate i regulirate,
05:06
you will get that aerodynamicaerodinamičan efficiencyefikasnost.
86
291000
3000
dobiti ćete aerodinamičku učinkovitost.
05:09
So the overallCjelokupni consumptionpotrošnja of energyenergija
87
294000
3000
Dakle, ukupna potrošnja energije
05:12
is about 25 wattsvata at takeoffpolijetanje
88
297000
3000
je oko 25 vati prilikom polijetanja
05:15
and 16 to 18 wattsvata in flightlet.
89
300000
3000
i 16 do 18 vati u letu.
05:18
Thank you.
90
303000
2000
Hvala vam.
