So this video was taken
1
8811
1903
Denne video er optaget
00:22
at Aquarius undersea laboratory
2
10714
2432
ved Aquarius undervands laboratorium
00:25
four miles off the coast of Key Largo,
3
13146
1853
6,5 km. ud for Key Largos kyst
00:26
about 60 feet below the surface.
4
14999
2578
omkring 20 m. under havets overflade.
00:29
NASA uses this extreme environment
5
17577
1724
NASA bruger dette ekstreme miljø
00:31
to train astronauts and aquanauts,
6
19301
2424
til at træne astronauter og aquanauter,
00:33
and last year, they invited us along for the ride.
7
21725
3362
og sidste år, blev vi inviteret med.
00:37
All the footage was taken from our open ROV,
8
25087
2884
Alle disse optagelse er fra vores "open ROV",
00:39
which is a robot that we built in our garage.
9
27971
4487
som er en robot vi har bygget i vores garage.
00:44
So ROV stands for Remote Operated Vehicle,
10
32458
3568
ROV står for Remote Operated Vehicle, (fjernstyret fartøj)
00:48
which in our case means our little robot
11
36026
1527
Vores lille robot sender
00:49
sends live video
12
37553
2264
billeder direkte
00:51
across that ultra-thin tether
13
39817
1918
via en ultra tynd ledning
00:53
back to the computer topside.
14
41735
2428
tilbage til computeren oppe på overfladen.
00:56
It's open source, meaning we publish
15
44163
1978
Den er open source (åben kilde), hvilket betyder at alle
00:58
and share all of our design files
16
46141
2045
vores design filer
01:00
and all of our code online,
17
48186
1508
al vores kode er tilgængelig på nettet,
01:01
allowing anyone to modify
18
49694
2034
så alle kan justere
01:03
or improve or change the design.
19
51728
2349
eller forbedre eller ændre designet.
01:06
It's built with mostly off-the-shelf parts
20
54077
2303
Den er bygget af let tilgængelige dele
01:08
and costs about 1,000 times cheaper
21
56380
1835
koster en promille af hvad
01:10
than the ROVs James Cameron used
22
58215
1879
den ROV som James Cameron brugte
01:12
to explore the Titanic.
23
60094
3605
til at udforske Titanic.
01:15
So ROVs aren't new.
24
63699
2210
ROV'er er ikke en ny ting.
01:17
They've been around for decades.
25
65909
1708
De har været brugt i årtier.
01:19
Scientists use ROVs to explore the oceans.
26
67617
3036
forskere bruger ROV'er til at udforske havene.
01:22
Oil and gas companies use them for exploration
27
70653
2819
Olie og gas selskaber bruger dem til udforskning
01:25
and construction.
28
73472
1547
og anlægsarbejde.
01:27
What we've built isn't unique.
29
75019
2762
Det vi har bygget er ikke unikt.
01:29
It's how we've built it that's really unique.
30
77781
2874
Det er måden vi har bygget det på, som er unikt.
01:32
So I want to give you a quick story
of how it got started.
of how it got started.
31
80655
2981
Lad mig give jeg historien om hvordan det startede.
01:35
So a few years ago, my friend Eric and I
32
83636
2271
For et par år siden besluttede min ven Eric og jeg
01:37
decided we wanted to explore this underwater cave
33
85907
2200
at vi ville udforske en undervandsgrotte
01:40
in the foothills of the Sierras.
34
88107
1858
ved foden af Sierra bjergene.
01:41
We had heard this story about lost gold
35
89965
1903
Vi havde hørt en historie om forsvundet guld
01:43
from a Gold Rush-era robbery,
and we wanted to go up there.
and we wanted to go up there.
36
91868
2518
fra et røveri i guldfeber tiden, og der ville vi gerne hen.
01:46
Unfortunately, we didn't have any money
37
94386
1658
Vi havde desværre ingen penge
01:48
and we didn't have any tools to do it.
38
96044
1823
og vi havde ingen værktøjer til at gøre det.
01:49
So Eric had an initial design idea for a robot,
39
97867
3200
Eric havde en design idé til en robot,
01:53
but we didn't have all the parts figured out,
40
101067
2773
men vi havde ikke alle delene til at bygge den,
01:55
so we did what anybody would do in our situation:
41
103840
2212
så vi gjorde hvad alle andre i vores situation ville have gjort:
01:58
we asked the Internet for help.
42
106052
2038
vi bad internettet om hjælp.
02:00
More specifically, we created this website,
43
108090
2532
Helt præcist, byggede vi en hjemmeside,
02:02
openROV.com, and shared
our intentions and our plans
our intentions and our plans
44
110622
2895
openROV.com, og delte vores tegninger og idéer.
02:05
For the first few months, it was just Eric and I
45
113517
2390
I de første par måneder var det kun Eric og jeg
02:07
talking back to each other on the forums,
46
115907
2530
som kommunikerede i foraene,
02:10
but pretty soon, we started to get feedback
47
118437
2088
men ret hurtig, begyndte vi at få tilbagemeldinger
02:12
from makers and hobbyists,
48
120525
1843
fra gør-det-selv folk og hobbybyggere,
02:14
and then actually professional ocean engineers
49
122368
1994
og også professionelle marineingeniører
02:16
who had some suggestions for what we should do.
50
124362
3532
som havde forslag til hvad vi kunne gøre.
02:19
We kept working on it. We learned a lot.
51
127894
1764
Vi fortsatte arbejdet. Vi lærte en masse.
02:21
We kept prototyping, and eventually,
52
129658
2025
Vi blev ved med at bygge prototyper, og til sidst,
02:23
we decided we wanted to go
to the cave. We were ready.
to the cave. We were ready.
53
131683
2719
besluttede vi at vi var klar til at tage ud til grotten.
02:26
So about that time, our little expedition
became quite a story,
became quite a story,
54
134402
3440
På det tidspunkt var vores lille ekspedition blevet en ret stor historie
02:29
and it got picked up in The New York Times.
55
137842
2021
og den blev taget op af The New York Times.
02:31
And we were pretty much just overwhelmed
56
139863
1812
Der var en overvældende interesse
02:33
with interest from people who wanted a kit
57
141675
1783
fra folk som ville have et byggesæt
02:35
that they could build this open ROV themselves.
58
143458
2521
så de selv kunne bygge en "open ROV".
02:37
So we decided to put the project on Kickstarter,
59
145979
3289
så vi besluttede at åbne et projekt på Kickstarter,
02:41
and when we did,
60
149268
1232
og da vi gjorde det,
02:42
we raised our funding goal in about two hours,
61
150500
2075
vi nåede vores finansieringsmål på to timer,
02:44
and all of a sudden,
had this money to make these kits.
had this money to make these kits.
62
152575
3205
og nu havde vi pludselig råd til at lave byggesættene.
02:47
But then we had to learn how to make them.
63
155780
2195
Men vi var nød til at lære hvordan vi skulle lave dem.
02:49
I mean, we had to learn small batch manufacturing.
64
157975
2165
Vi var nød til at lære at producere et mindre parti.
02:52
So we quickly learned that our garage
65
160140
3260
Vi fandt hurtigt ud af at vores garage
02:55
was not big enough to hold our growing operation.
66
163400
2679
ikke var stor nok til vores projekt.
02:58
But we were able to do it, we got all the kits made,
67
166079
2156
Men det lykkedes os, vi fik alle byggesættene klar,
03:00
thanks a lot to TechShop,
which was a big help to us,
which was a big help to us,
68
168235
2707
stor tak til TechShop, som var en stor hjælp,
03:02
and we shipped these kits all over the world
69
170942
2985
og vi sendte byggesættene til alle dele af verden
03:05
just before Christmas of last year,
70
173927
1829
lige før jul sidste år,
03:07
so it was just a few months ago.
71
175756
1782
så ikke mere end at par måneder siden.
03:09
But we're already starting to get video
72
177538
1908
Men vi har allerede modtaget videoer
03:11
and photos back from all over the world,
73
179446
1598
og billeder tilbage fra hele verden,
03:13
including this shot from under the ice in Antarctica.
74
181044
3030
også dette klip optaget under isen på Antarktis.
03:16
We've also learned the penguins love robots.
75
184074
3400
Vi har også fundet ud af at pingviner elsker robotter.
03:19
(Laughter)
76
187474
2013
(Latter)
03:21
So we're still publishing all the designs online,
77
189487
3168
Vi deler stadig alle vores tegninger på nettet,
03:24
encouraging anyone to build these themselves.
78
192655
2118
opfordrer alle til at bygge dem selv.
03:26
That's the only way that we could have done this.
79
194773
2403
Det var den eneste måde vi kunne klare det.
03:29
By being open source, we've created
80
197176
1659
Ved at være open source, har vi skabt
03:30
this distributed R&D network,
81
198835
2264
et udviklings og design netværk,
03:33
and we're moving faster than
any venture-backed counterpart.
any venture-backed counterpart.
82
201099
3796
og det går hurtigere end noget andet traditionelt finansieret projekt.
03:36
But the actual robot is really only half the story.
83
204895
3205
Men robotterne er faktisk kun halvdelen af historien.
03:40
The real potential, the long term potential,
84
208100
2496
Det sande potentiale, potentialet på lang sigt,
03:42
is with this community of DIY ocean explorers
85
210596
2677
ligger i det fællesskab af gør-det-selv marine forskere
03:45
that are forming all over the globe.
86
213273
2396
som vokser frem over hele kloden.
03:47
What can we discover
87
215669
1534
Hvad kan vi opdage
03:49
when there's thousands of these devices
88
217203
1904
med tusinder af disse robotter
03:51
roaming the seas?
89
219107
2046
svømmende rundt i havene?
03:53
So you're probably all wondering: the cave.
90
221153
2276
I tænker sikkert alle sammen på: grotten.
03:55
Did you find the gold?
91
223429
1826
Fandt I guldet?
03:57
Well, we didn't find any gold,
92
225255
1552
Vi fandt ikke noget guld,
03:58
but we decided that what we found
was much more valuable.
was much more valuable.
93
226807
3229
men vi blev enige om at det vi fandt var meget mere værdifuldt.
04:02
It was the glimpse into a potential future
94
230036
2472
Det var et glimt af mulig fremtid
04:04
for ocean exploration.
95
232508
1675
indenfor marine forskning.
04:06
It's something that's not limited to
the James Camerons of the world,
the James Camerons of the world,
96
234183
2910
Det er ikke kun verdens James Cameron'er forundt,
04:09
but something that we're all participating in.
97
237093
2595
det er noget vi alle kan deltage i.
04:11
It's an underwater world
98
239688
1333
Det er en verden under vand
04:13
we're all exploring together.
99
241021
2511
vi alle udforsker sammen.
04:15
Thank you.

ABOUT THE SPEAKER
David Lang - MakerDavid Lang is a maker and the co-founder of OpenROV, a community of ocean lovers who build underwater robots.
Why you should listen
David Lang is a maker whose craving for adventure turned him into an amateur ocean explorer. A few years ago Lang and NASA engineer Eric Stackpole went looking for lost gold (literally) in an underwater cave in the foothills of the Sierra Navada. But they weren't quite sure how to go about it. Without much expertise (or money), the two put initial designs for an underwater robot explorer online. Soon OpenROV was born: a community of citizen ocean explorers who build and constantly improve upon these small remote operated underwater robots.
Lang is also the author of Zero to Maker and a 2013 TED Fellow. He lives on a sailboat in the San Francisco Bay.
