00:12
Even nature's most disgusting creatures
0
12930
2904
Čak i najodvratnija stvorenja u prirodi
00:15
have important secrets,
1
15834
2567
imaju bitne tajne,
00:18
but who would want a swarm of cockroaches
2
18401
1489
ali tko bi želio roj žohara
00:19
coming towards them?
3
19890
1594
da hrli ka njemu?
00:21
Yet one of the greatest differences between natural and human technologies
4
21484
3012
Jedna od najvećih razlika između prirodnih i ljudskih tehnologija
00:24
relates to robustness.
5
24496
2215
se odnosi na robusnost.
00:26
Robust systems are stable in complex
6
26711
2573
Robusni sustavi su stabilni u složenim
00:29
and new environments.
7
29284
1721
i novim okolinama.
00:31
Remarkably, cockroaches can self-stabilize
8
31005
1795
Upečatljivo, žohari se mogu samostablizirati
00:32
running over rough terrain.
9
32800
1679
trčeći preko grubog terena.
00:34
When we put a jet pack on them,
10
34479
1262
Kada na njih stavimo jet pack
00:35
or give them a perturbation like an earthquake,
11
35741
2011
ili im smetamo poput potresa,
00:37
we discovered that their wonderfully tuned legs
12
37752
2891
otkrili smo da im njihove prekrasno podešene noge
00:40
allow them to self-stabilize
13
40643
1625
omogućuju da se samostabiliziraju
00:42
without using any of their brainpower.
14
42268
3662
bez da koriste išta svoje snage mozga.
00:45
They can go over complex terrain like grass,
15
45930
3130
Mogu šetati preko složenih terena kao što je trava,
00:49
no problem, and not get destabilized.
16
49060
1952
bez problema, i ne budu destabilizirani.
00:51
We discovered a new behavior where,
17
51012
1514
Otkrili smo novo ponašanje gdje,
00:52
because of their shape,
18
52526
1164
zbog svog oblika,
00:53
they actually roll automatically to their side
19
53690
2078
oni se automatski prevrnu na bok
00:55
to go through this artificial test bit of grass.
20
55768
3952
kako bi prošli kroz ovu umjetnu testnu travu.
00:59
Robust systems can perform multiple tasks
21
59720
2437
Robusni sustavi mogu obavljati više zadataka
01:02
with the same structure.
22
62157
2138
s istom strukturom.
01:04
Here's a new behavior we've discovered.
23
64295
1867
Ovdje je novo ponašanje koje smo otkrili.
01:06
The animals rapidly invert and disappear
24
66162
1846
Životinje se brzo obrnu i nestanu
01:08
in less than 150 milliseconds — you never see them —
25
68008
2501
u manje od 150 milisekundi - nikad ih ne vidite -
01:10
using the same structures that they use to run, their legs.
26
70509
2363
koristeći iste strukture koje koriste za trčanje, svoje noge.
01:12
They can run upside down
27
72872
1604
Mogu trčati naglavce
01:14
very rapidly on rods, branches and wires,
28
74476
3132
vrlo brzo na štapovima, granama i žicama,
01:17
and if you perturb one of those branches,
29
77608
1479
i ako izmjenimo jednu od tih grana,
01:19
they can do this.
30
79087
1793
oni mogu učiniti ovo.
01:20
They can perform gymnastic maneuvers
31
80880
1530
Mogu raditi gimnastičke manevre
01:22
like no robot we have yet.
32
82410
2578
koje ne može nijedan robot kojeg imamo.
01:24
And they have nearly unlimited
33
84988
1731
I imaju gotovo neograničenu
01:26
maneuverability with that same structure
34
86719
2597
pokretljivost sa istom tom strukturom
01:29
and unprecedented access to a variety
35
89316
3820
i nepremašan pristup mnogim
01:33
of different areas.
36
93136
4270
različitim područjima.
01:37
They have wings for flying when they get warm,
37
97406
2623
Imaju krila kako bi letjeli kada se zagriju,
01:40
but they use those same wings to flip over
38
100029
2614
ali koriste ta krila i kako bi se okrenuli
01:42
if they get destabilized.
39
102643
3957
ako se destabiliziraju.
01:46
Very effective.
40
106600
1297
Vrlo učinkovito.
01:47
Robust systems are also fault tolerant and fail-safe.
41
107897
3205
Robusni sustavi toleriraju greške i sigurni su od prekida rada.
01:51
This is the foot of a cockroach.
42
111102
1140
Ovo je stopalo žohara.
01:52
It has spines, gluey pads and claws,
43
112242
3289
Ima bodlje, ljepljive pločice i kandže,
01:55
but if you take off those feet,
44
115531
1591
ali ako uklonite jednu nogu,
01:57
they can still go over rough terrain,
45
117122
1708
oni se i dalje mogu kretati preko teškog terena,
01:58
like the bottom video that you see,
46
118830
1897
kao u snimci koji vidite,
02:00
without hardly slowing down. Extraordinary.
47
120727
3371
bez da se imalo uspore. Nevjerojatno.
02:04
They can run up mesh without their feet.
48
124098
3173
Mogu trčati uz mrežu bez nogu.
02:07
Here's an animal using a normal, alternating tripod:
49
127271
2283
Ovdje je životinja koja koristi normalni, izmjenjujući tronožac:
02:09
three legs, three legs, three legs,
50
129554
1543
tri noge, tri noge, tri noge,
02:11
but in nature, the insects often have lost their legs.
51
131097
3692
ali u prirodi, insekti često izgube noge.
02:14
Here's one moving with two middle legs gone.
52
134789
4010
Ovdje je jedan koji se kreće bez dvije središnje noge.
02:18
It can even lose three legs, in a tripod,
53
138799
2916
Može čak izgubiti i tri noge, u tronošca,
02:21
and adopt a new gait, a hopping gait.
54
141715
3927
i prihvatiti novi hod, poskakivajući hod.
02:25
And I point out that all of these videos
55
145642
1958
I napominjem da su sve ove snimke
02:27
are slowed down 20 times,
56
147600
1704
usporeni 20 puta,
02:29
so they're actually really fast, when you see this.
57
149304
2015
tako da su zapravo jako brzi, kada to vidite.
02:31
Robust systems are also damage resistant.
58
151319
3511
Robusni sustavi su otporni i na štetu.
02:34
Here's an animal climbing up a wall.
59
154830
1813
Ovdje je životinja koja se penje uza zid.
02:36
It looks like a rapid, smooth, vertical climb,
60
156643
2496
Izgleda kao brz, gladak, vertikalni uspon,
02:39
but when you slow it down,
61
159139
1239
ali kada to usporite,
02:40
you see something very different.
62
160378
2494
vidite nešto potpuno drugačije.
02:42
Here's what they do.
63
162872
1648
Evo što čine.
02:44
They intentionally have a head-on collision with the wall
64
164520
3007
Namjerno se zabijaju glavom u zid
02:47
so they don't slow down and can transition up it
65
167527
2114
tako da ne uspore i mogu se nastaviti kretati uz njega
02:49
in 75 milliseconds.
66
169641
2398
u 75 milisekundi.
02:52
And they can do this in part because they have
67
172039
1861
I to djelomično mogu činiti jer imaju
02:53
extraordinary exoskeletons.
68
173900
2057
nevjerojatne vanjske egzoskelete.
02:55
And they're really just made up of compliant joints
69
175957
3809
I zapravo su napravljeni od prilagodljivih zglobova
02:59
that are tubes and plates
70
179766
1733
koji su cijevi i pločice
03:01
connected to one another.
71
181499
1543
povezane jedne s drugima.
03:03
Here's a dissection of an abdomen of a cockroach.
72
183042
2947
Ovo je disekcija abdomena žohara.
03:05
You see these plates, and you see the compliant membrane.
73
185989
3961
Ovdje vidite pločice i prilagodljivu membranu.
03:09
My engineering colleague at Berkeley
74
189950
2816
Moj kolega inžinjer s Berkeleya
03:12
designed with his students
75
192766
1124
dizajnirao je sa svojim studentima
03:13
a novel manufacturing technique
76
193890
1481
novu tehnologiju proizvodnje
03:15
where you essentially origami the exoskeleton,
77
195371
3611
gdje u osnovi slažete egzoskelet poput origamija,
03:18
you laser cut it, laminate it,
78
198982
1360
režete ga laserom, oblažete ga,
03:20
and you fold it up into a robot.
79
200342
2395
i onda ga slažete u robota.
03:22
And you can do that now in less than 15 minutes.
80
202737
5817
I možete to sada činiti u manje od 15 minuta.
03:28
These robots, called DASH,
81
208554
1939
Ovi roboti, nazvani DASH
03:30
for Dynamic Autonomous Sprawled Hexapod,
82
210493
2610
kratica za Dinamički Autonomni Opruženi (Sprawled) Heksapod,
03:33
are highly compliant robots,
83
213103
3082
su vrlo prilagodljivi roboti,
03:36
and they're remarkably robust as a result
84
216185
3702
i oni su vrlo robusni kao rezultat
03:39
of these features.
85
219887
1803
svih ovih karakteristika.
03:41
They're certainly incredibly damage resistant.
86
221690
6058
Zasigurno su vrlo otporni na oštećivanje.
03:47
(Laughter)
87
227748
3353
(Smijeh)
03:51
They even have some of the behaviors of the cockroaches.
88
231101
2469
Čak imaju i neka ponašanja žohara.
03:53
So they can use their smart, compliant body
89
233570
2273
Tako da mogu koristiti svoja pametna, prilagodljiva tijela
03:55
to transition up a wall
90
235843
2517
da bi se penjali uza zid
03:58
in a very simple way.
91
238360
2892
na vrlo jednostavan način.
04:01
They even have some of the beginnings
92
241252
1628
Čak imaju i neke početke
04:02
of the rapid inversion behavior
93
242880
1319
ponašanja brzog okreta
04:04
where they disappear.
94
244199
2844
gdje nestaju.
04:07
Now we want to know why they can go anywhere.
95
247043
1477
Sada želimo znati zašto mogu ići bilo gdje.
04:08
We discovered that they can go through
96
248520
1569
Otkrili smo da mogu proći kroz
04:10
three-millimeter gaps,
97
250089
1788
procjepe od tri milimetra,
04:11
the height of two pennies, two stacked pennies,
98
251877
2361
visine dva novčića, dva novčića jedan na drugom,
04:14
and when they do this,
99
254238
1048
i kada to čine,
04:15
they can actually run through those confined spaces
100
255286
2575
mogu zapravo trčati kroz te skučene prostore
04:17
at high speeds,
101
257861
1757
velikim brzinama,
04:19
although you never see it.
102
259618
3182
iako ih nikad ne vide.
04:22
To understand it better,
103
262800
1062
Kako bismo bolje razumjeli,
04:23
we did a CT scan of the exoskeleton
104
263862
2078
napravili smo CT sken egzoskeleta
04:25
and showed that they can compress their body
105
265940
1474
i pokazali da mogu komprimirati svoje tijelo
04:27
by over 40 percent.
106
267414
2646
za 40 posto.
04:30
We put them in a materials testing machine
107
270060
1557
Stavili smo ih u uređaj za testiranje materijala
04:31
to look at the stress strain analysis
108
271617
2356
da vidimo analizu naprezanja
04:33
and showed that they can withstand forces
109
273973
2118
i pokazalo je da mogu izdržati sile
04:36
800 times their body weight,
110
276091
1904
800 puta veće od svoje težine,
04:37
and after this they can fly and run
111
277995
1890
i nakon toga mogu letjeti i trčati
04:39
absolutely normally.
112
279885
1990
potpuno normalno.
04:41
So you never know where
113
281875
1723
Tako da nikad ne znate gdje
04:43
curiosity-based research will lead,
114
283598
3074
će nas istraživanje bazirano na znatiželji odvesti,
04:46
and someday you may want a swarm
115
286672
1539
i jednog dana ćete možda htjeti roj
04:48
of cockroach-inspired robots
116
288211
2194
žoharima inspiriranih robota
04:50
to come at you.
117
290405
2414
da vam priđu.
04:52
(Laughter)
118
292819
7121
(Smijeh)
04:59
Thank you.
119
299940
1557
Hvala vam.
05:01
