00:12
This is me building a prototype
1
12346
2770
Ovde možete videti mene kako pravim jedan prototip
00:15
for six hours straight.
2
15116
2920
čitavih šest sati.
00:18
This is slave labor to my own project.
3
18036
3921
Ovo je robovski rad za moj projekat.
00:21
This is what the DIY and maker movements really look like.
4
21957
4990
Ovako u stvari izgledaju "uradi sam" pokreti.
00:26
And this is an analogy for today's construction and manufacturing world
5
26947
4766
A ovo je i analogija današnjem svetu građevinarstva i proizvodnje
00:31
with brute-force assembly techniques.
6
31713
2788
i njihovim tehnikama sklapanja zasnovanim na sirovoj snazi.
00:34
And this is exactly why I started studying
7
34501
2834
I ovo je upravo i razlog što sam počeo da izučavam
00:37
how to program physical materials to build themselves.
8
37335
4269
kako programirati fizičke materijale da sami sebe grade.
00:41
But there is another world.
9
41604
1760
Ali postoji i drugi svet.
00:43
Today at the micro- and nanoscales,
10
43364
1995
Danas se na mikro i nano razmerama
00:45
there's an unprecedented revolution happening.
11
45359
2751
dešava neviđena revolucija.
00:48
And this is the ability to program physical and biological materials
12
48110
4132
Radi se o mogućnosti programiranja fizičkih i biloških materijala
00:52
to change shape, change properties
13
52242
2724
da menjaju oblik, menjaju svojstva
00:54
and even compute outside of silicon-based matter.
14
54966
2986
i čak da proračunavaju izvan materije na bazi silicijuma.
00:57
There's even a software called cadnano
15
57952
2507
Postoji čak i softver po imenu "cadnano"
01:00
that allows us to design three-dimensional shapes
16
60459
2783
uz pomoć kojeg možemo da dizajniramo trodimenzionalne oblike
01:03
like nano robots or drug delivery systems
17
63242
3084
poput nanorobota ili sistema za dostavljanje lekova
01:06
and use DNA to self-assemble those functional structures.
18
66326
4303
i da koristimo DNK koji omogućava ovim funkcionalnim strukturama da se same sastave.
01:10
But if we look at the human scale,
19
70629
2073
Ali ukoliko obratimo pažnju na nivo čoveka,
01:12
there's massive problems that aren't being addressed
20
72702
3056
postoje ogromni problemi koji ostaju zanemareni
01:15
by those nanoscale technologies.
21
75758
2368
od strane tih nanotehnologija.
01:18
If we look at construction and manufacturing,
22
78126
2099
Ako pogledamo na građevinarstvo i proizvodnju,
01:20
there's major inefficiencies, energy consumption
23
80225
4193
naići ćemo na veliku neefikasnost, potrošnju energije
01:24
and excessive labor techniques.
24
84418
2327
i opsežne tehnike rada.
01:26
In infrastructure, let's just take one example.
25
86745
2505
U infrastrukturi, hajde da uzmemo samo jedan primer.
01:29
Take piping.
26
89250
1483
Recimo vodovodni sistem.
01:30
In water pipes, we have fixed-capacity water pipes
27
90733
3725
U vodovodnim cevima imamo cevi fiksnog kapaciteta
01:34
that have fixed flow rates, except for expensive pumps and valves.
28
94458
4459
sa fiksnim protokom, ako izuzmemo skupe pumpe i ventile.
01:38
We bury them in the ground.
29
98917
1291
Zakopavamo ih u zemlju.
01:40
If anything changes -- if the environment changes,
30
100208
2621
Ako se bilo šta promeni - ako se životna sredina promeni,
01:42
the ground moves, or demand changes --
31
102829
2637
ako dođe do pomeranja tla, ili promene potrošnje -
01:45
we have to start from scratch and take them out and replace them.
32
105466
4250
moramo da počnemo od nule, da ih izvadimo i zamenimo
01:49
So I'd like to propose that we can combine those two worlds,
33
109716
3368
Zato bih želeo da predložim da iskombinujemo ta dva sveta,
01:53
that we can combine the world of the nanoscale programmable adaptive materials
34
113084
5171
možemo da iskombinujemo svet prilagodljivih nanomaterijala sa mogućnošću programiranja
01:58
and the built environment.
35
118255
1677
i izgrađeni deo okruženja.
01:59
And I don't mean automated machines.
36
119932
2186
Pod tim ne mislim na automatizovane mašine.
02:02
I don't just mean smart machines that replace humans.
37
122118
2459
Ne mislim samo na inteligentne mašine koje mogu da zamene ljude.
02:04
But I mean programmable materials that build themselves.
38
124577
3884
Mislim na materijale koji se mogu programirati i koji izgrađuju sami sebe.
02:08
And that's called self-assembly,
39
128461
2056
A to se zove samosklapanje,
02:10
which is a process by which disordered parts build an ordered structure
40
130517
4517
što je proces pri kome neuređeni delovi grade uređenu strukturu
02:15
through only local interaction.
41
135034
2493
kroz isključivo lokalnu interakciju.
02:17
So what do we need if we want to do this at the human scale?
42
137527
3175
Šta nam je potrebno ukoliko želimo ovo da izvedemo na nivou čoveka?
02:20
We need a few simple ingredients.
43
140702
1975
Potrebno nam je nekoliko jednostavnih sastojaka.
02:22
The first ingredient is materials and geometry,
44
142677
2839
Prvi sastojak su materijali i geometrija,
02:25
and that needs to be tightly coupled with the energy source.
45
145516
3469
a oni moraju biti tesno povezani sa izvorom energije.
02:28
And you can use passive energy --
46
148985
1658
Možete koristiti pasivnu energiju -
02:30
so heat, shaking, pneumatics, gravity, magnetics.
47
150643
4684
toplotu, potrese, pneumatiku, gravitaciju, magnetizam.
02:35
And then you need smartly designed interactions.
48
155327
3075
Sledeće što trebate su pametno osmišljene interakcije.
02:38
And those interactions allow for error correction,
49
158402
2133
Te interakcije omogućavaju ispravljanje grešaka,
02:40
and they allow the shapes to go from one state to another state.
50
160535
4000
i dozvoljavaju oblicima da prelaze iz jednog stanja u drugo.
02:44
So now I'm going to show you a number of projects that we've built,
51
164535
3232
Sada ću da vam pokažem nekoliko projekata koje smo izgradili,
02:47
from one-dimensional, two-dimensional, three-dimensional
52
167767
3284
od jednodimenzionalnih, dvodimenzionalnih, trodimenzionalnih,
02:51
and even four-dimensional systems.
53
171051
3067
pa čak i četvorodimenzionalnih sistema.
02:54
So in one-dimensional systems --
54
174118
1886
U jednodimenzionalnim sistemima -
02:56
this is a project called the self-folding proteins.
55
176004
2907
ovo je projekat pod nazivom samosavijajući proteini.
02:58
And the idea is that you take the three-dimensional structure of a protein --
56
178911
4707
Ideja je da uzmete trodimenzionalnu strukturu proteina -
03:03
in this case it's the crambin protein --
57
183618
2681
u ovom slučaju to je protein po imenu krambin -
03:06
you take the backbone -- so no cross-linking, no environmental interactions --
58
186299
3646
uzmete mu kičmu - znači nema međusobnog vezivanja, nema sredinskih uticaja -
03:09
and you break that down into a series of components.
59
189945
3151
i razbijete ga na seriju komponenti.
03:13
And then we embed elastic.
60
193096
2274
I tada umećemo lastiš.
03:15
And when I throw this up into the air and catch it,
61
195370
2341
Kada ga bacim u vazduh i uhvatim,
03:17
it has the full three-dimensional structure of the protein, all of the intricacies.
62
197711
4851
on ima punu trodimenzionalnu strukturu tog proteina, sve do najmanje pojedinosti.
03:22
And this gives us a tangible model
63
202562
2100
Ovo nam pruža opipljiv model
03:24
of the three-dimensional protein and how it folds
64
204662
3734
trodimenzionalnog proteina i načina na koji se savija
03:28
and all of the intricacies of the geometry.
65
208396
2284
i svih pojedinosti njegove geometrije.
03:30
So we can study this as a physical, intuitive model.
66
210680
3448
Dakle ovo možemo da proučavamo kao fizički, intuitivni model.
03:34
And we're also translating that into two-dimensional systems --
67
214128
2802
Ovo takođe prenosimo i u dvodimenzionalne sisteme -
03:36
so flat sheets that can self-fold into three-dimensional structures.
68
216930
4299
dakle ravni listovi koji mogu sami da se saviju u trodimenzionalne strukture.
03:41
In three dimensions, we did a project last year at TEDGlobal
69
221229
4453
U tri dimenzije, prošle godine smo radili projekat na TEDGlobal-u
03:45
with Autodesk and Arthur Olson
70
225682
1964
sa Autodeskom i Arturom Olsonom
03:47
where we looked at autonomous parts --
71
227646
1698
gde smo posmatrali nezavisne delove -
03:49
so individual parts not pre-connected that can come together on their own.
72
229344
4319
znači individualne delove koji nisu bili prethodno povezani i koji mogu sami da se sastave.
03:53
And we built 500 of these glass beakers.
73
233663
2766
Napravili smo 500 ovakvih staklenih pehara.
03:56
They had different molecular structures inside
74
236429
2467
Unutra su bile različite molekularne strukture
03:58
and different colors that could be mixed and matched.
75
238896
2224
i različite boje koje su mogle da se mešaju i uparuju.
04:01
And we gave them away to all the TEDsters.
76
241120
2249
I podelili smo ih svim TEDsterima.
04:03
And so these became intuitive models
77
243369
2501
Tako su oni postali intuitivni modeli
04:05
to understand how molecular self-assembly works at the human scale.
78
245870
3492
za razumevanje kako molekularno samosklapanje funkcioniše na ljudskom nivou.
04:09
This is the polio virus.
79
249362
1817
Ovo je poliovirus.
04:11
You shake it hard and it breaks apart.
80
251179
1932
Snažno ga protresete i on se raspadne.
04:13
And then you shake it randomly
81
253111
1446
Zatim ga tresete nasumično
04:14
and it starts to error correct and built the structure on its own.
82
254557
3504
i on počinje da ispravlja greške i samostalno gradi svoju strukturu.
04:18
And this is demonstrating that through random energy,
83
258061
2967
Ovo pokazuje da pomoću varirajuće energije,
04:21
we can build non-random shapes.
84
261028
4628
možemo kreirati pravilne oblike.
04:25
We even demonstrated that we can do this at a much larger scale.
85
265656
3524
Čak smo pokazali i da je ovo moguće izvesti i u mnogo većoj razmeri.
04:29
Last year at TED Long Beach,
86
269180
2154
Prošle godine na TED-u u Long Biču,
04:31
we built an installation that builds installations.
87
271334
3211
napravili smo instalaciju koja pravi instalacije.
04:34
The idea was, could we self-assemble furniture-scale objects?
88
274545
3537
Pitali smo se da li se predmeti u razmerima nameštaja mogu sami sastaviti.
04:38
So we built a large rotating chamber,
89
278082
2501
Pa smo napravili veliku rotirajuću komoru,
04:40
and people would come up and spin the chamber faster or slower,
90
280583
3213
a ljudi su mogli da se popnu i da je zavrte brže ili sporije,
04:43
adding energy to the system
91
283796
1585
i da tako dodaju energiju sistemu
04:45
and getting an intuitive understanding of how self-assembly works
92
285381
3446
i da steknu intuitivno razumevanje kako samosklapanje funkcioniše
04:48
and how we could use this
93
288827
1379
i kako bismo ovo mogli da iskoristimo
04:50
as a macroscale construction or manufacturing technique for products.
94
290206
4746
kao tehniku za izgradnju na makro nivou ili u proizvodnji.
04:54
So remember, I said 4D.
95
294952
1667
Da vas podsetim, rekao sam 4D.
04:56
So today for the first time, we're unveiling a new project,
96
296619
3695
Danas po prvi put, predstavljamo jedan nov projekat,
05:00
which is a collaboration with Stratasys,
97
300314
1886
koji je nastao u saradnji sa Stratasys,
05:02
and it's called 4D printing.
98
302200
1835
i zove se 4D štampanje.
05:04
The idea behind 4D printing
99
304035
1960
Princip na kome se zasniva 4D štampanje
05:05
is that you take multi-material 3D printing --
100
305995
3000
je da uzmete 3D štampanje različitih materijala -
05:08
so you can deposit multiple materials --
101
308995
2189
da biste deponovali raznovrsne materijale -
05:11
and you add a new capability,
102
311184
1884
i pridodate novu sposobnost,
05:13
which is transformation,
103
313068
1866
što je transformacija,
05:14
that right off the bed,
104
314934
1317
tako da pravo sa štamparske ploče
05:16
the parts can transform from one shape to another shape directly on their own.
105
316251
4327
ti delovi mogu sami da se transformišu direktno iz jednog oblika u drugi.
05:20
And this is like robotics without wires or motors.
106
320578
3500
Ovo je kao robotika ali bez kablova i motora.
05:24
So you completely print this part,
107
324078
1651
Tako da potpuno odštampate taj deo,
05:25
and it can transform into something else.
108
325729
2804
a on može da se pretvori u nešto drugo.
05:28
We also worked with Autodesk on a software they're developing called Project Cyborg.
109
328533
4961
Sa Autodeskom smo radili i na softveru koji oni trenutno razvijaju pod nazivom Project Cyborg.
05:33
And this allows us to simulate this self-assembly behavior
110
333494
3123
Ovo nam dozvoljava da simuliramo samosklapanje
05:36
and try to optimize which parts are folding when.
111
336617
3202
i da pokušamo da podesimo kada će se koji delovi savijati.
05:39
But most importantly, we can use this same software
112
339819
2730
Ali najznačajnije je što možemo koristiti ovaj isti softver
05:42
for the design of nanoscale self-assembly systems
113
342549
2908
za kreiranje samosklapajućih sistema na nano nivou
05:45
and human scale self-assembly systems.
114
345457
2843
kao i onih na nivou čoveka.
05:48
These are parts being printed with multi-material properties.
115
348300
3513
Ovo je štampanje delova sa multimaterijalnim svojstvima.
05:51
Here's the first demonstration.
116
351813
1717
Ovo je prva demonstracija.
05:53
A single strand dipped in water
117
353530
1904
Jedna nit potopljena u vodu
05:55
that completely self-folds on its own
118
355434
2349
koja se savija u potpunosti sama od sebe
05:57
into the letters M I T.
119
357783
3918
u slova M I T.
06:01
I'm biased.
120
361701
1822
Pristrasan sam.
06:03
This is another part, single strand, dipped in a bigger tank
121
363523
3449
Ovo je drugi deo, jedna nit, potopljena u veći sud
06:06
that self-folds into a cube, a three-dimensional structure, on its own.
122
366972
4623
koja se samosavija u kocku, trodimenzionalnu strukturu, sama od sebe.
06:11
So no human interaction.
123
371595
1851
Dakle bez ljudske interakcije.
06:13
And we think this is the first time
124
373446
1889
Smatramo da je ovo prvi put
06:15
that a program and transformation
125
375335
2247
da su jedan program i transformacija
06:17
has been embedded directly into the materials themselves.
126
377582
3250
umetnuti direktno u same materijale.
06:20
And it also might just be the manufacturing technique
127
380832
2730
A ovo može biti i samo jedna tehnika proizvodnje
06:23
that allows us to produce more adaptive infrastructure in the future.
128
383562
4134
koja nam omogućava da u budućnosti proizvedemo prilagodljiviju infrastrukturu.
06:27
So I know you're probably thinking,
129
387696
1186
Znam da sad verovatno mislite
06:28
okay, that's cool, but how do we use any of this stuff for the built environment?
130
388882
4232
okej, to je kul, ali kako da bilo šta od ovoga iskoristimo u izgradnji?
06:33
So I've started a lab at MIT,
131
393114
2255
Otvorio sam laboratoriju na MIT-ju
06:35
and it's called the Self-Assembly Lab.
132
395369
1882
koja se zove Laboratorija za samosklapanje.
06:37
And we're dedicated to trying to develop programmable materials
133
397251
3144
Posvetili smo se razvijanju materijala sa mogućnošću programiranja
06:40
for the built environment.
134
400395
1191
za izgradnju okruženja.
06:41
And we think there's a few key sectors
135
401586
1963
Smatramo da postoji nekoliko ključnih sektora
06:43
that have fairly near-term applications.
136
403549
2314
u kojima postoji mogućnost prilično skore primene.
06:45
One of those is in extreme environments.
137
405863
2055
Jedan od njih su ekstremna okruženja.
06:47
These are scenarios where it's difficult to build,
138
407918
2546
Ovo su scenarija kada je gradnja otežana,
06:50
our current construction techniques don't work,
139
410464
2488
naše trenutne građevinske tehnike ne funkcionišu,
06:52
it's too large, it's too dangerous, it's expensive, too many parts.
140

kada je nešto preveliko, preopasno, preskupo ili se sastoji iz previše delova.
06:56
And space is a great example of that.
141
416512
2367
Prostor je odličan primer za to.
06:58
We're trying to design new scenarios for space
142
418879
2366
Pokušavamo da dizajniramo nove scenarije za prostor
07:01
that have fully reconfigurable and self-assembly structures
143
421245
3300
čije strukture bi imale mogućnost potpune rekonfiguracije i samosklapanja
07:04
that can go from highly functional systems from one to another.
144
424545
3690
koje bi mogle da prelaze iz visoko funkcionalnih sistema iz jednog u drugi.
07:08
Let's go back to infrastructure.
145
428235
2111
Hajde da se vratimo na infrastrukturu.
07:10
In infrastructure, we're working with a company out of Boston called Geosyntec.
146
430346

U oblasti infrastrukture, sarađujemo sa kompanijom iz Bostona po imenu "Geosyntec".
07:14
And we're developing a new paradigm for piping.
147
434245
2800
Razvijamo novu paradigmu za cevi.
07:17
Imagine if water pipes could expand or contract
148
437045
3623
Zamislite kad bi vodovodne cevi mogle da se šire ili skupljaju
07:20
to change capacity or change flow rate,
149
440668
2750
i tako menjaju svoj kapacitet ili protok,
07:23
or maybe even undulate like peristaltics to move the water themselves.
150
443418
4534
ili čak da se kreću u talasastim pokretma poput peristaltike da bi same pokretale vodu.
07:27
So this isn't expensive pumps or valves.
151
447952
2610
Dakle ovde se ne radi o skupim cevima i ventilima.
07:30
This is a completely programmable and adaptive pipe on its own.
152
450562
4283
Ovo je cev koja se samostalno i u potpunosti može programirati i adaptirati.
07:34
So I want to remind you today
153
454845
1815
Zato danas želim da vas podsetim
07:36
of the harsh realities of assembly in our world.
154
456660
3384
na okrutnu stvarnost sklapanja u našem svetu.
07:40
These are complex things built with complex parts
155
460044
3465
Postoje složene stvari sastavljene od složenih delova
07:43
that come together in complex ways.
156
463509
2785
koji se uklapaju na složene načine.
07:46
So I would like to invite you from whatever industry you're from
157
466294
3199
Pozivam vas, bez obzira iz koje ste industrije
07:49
to join us in reinventing and reimagining the world,
158
469493
4053
da nam se pridružite u reinvenciji i reimaginaciji sveta,
07:53
how things come together from the nanoscale to the human scale,
159
473546
3699
kako se stvari sastavljaju od nanosrazmera do nivoa čoveka,
07:57
so that we can go from a world like this
160
477245
3075
da bismo mogli da pređemo iz ovakvog sveta
08:00
to a world that's more like this.
161
480320
2950
u svet koji je više poput ovoga.
08:12
Thank you.
162
492632

Hvala vam.
