So this video was taken

Denne video er optaget

at Aquarius undersea laboratory

ved Aquarius undervands laboratorium

four miles off the coast of Key Largo,

6,5 km. ud for Key Largos kyst

about 60 feet below the surface.

omkring 20 m. under havets overflade.

NASA uses this extreme environment

NASA bruger dette ekstreme miljø

to train astronauts and aquanauts,

til at træne astronauter og aquanauter,

and last year, they invited us along for the ride.

og sidste år, blev vi inviteret med.

All the footage was taken from our open ROV,

Alle disse optagelse er fra vores "open ROV",

which is a robot that we built in our garage.

som er en robot vi har bygget i vores garage.

So ROV stands for Remote Operated Vehicle,

ROV står for Remote Operated Vehicle, (fjernstyret fartøj)

which in our case means our little robot

Vores lille robot sender

sends live video

billeder direkte

across that ultra-thin tether

via en ultra tynd ledning

back to the computer topside.

tilbage til computeren oppe på overfladen.

It's open source, meaning we publish

Den er open source (åben kilde), hvilket betyder at alle

and share all of our design files

vores design filer

and all of our code online,

al vores kode er tilgængelig på nettet,

allowing anyone to modify

så alle kan justere

or improve or change the design.

eller forbedre eller ændre designet.

It's built with mostly off-the-shelf parts

Den er bygget af let tilgængelige dele

and costs about 1,000 times cheaper

koster en promille af hvad

than the ROVs James Cameron used

den ROV som James Cameron brugte

to explore the Titanic.

til at udforske Titanic.

So ROVs aren't new.

ROV'er er ikke en ny ting.

They've been around for decades.

De har været brugt i årtier.

Scientists use ROVs to explore the oceans.

forskere bruger ROV'er til at udforske havene.

Oil and gas companies use them for exploration

Olie og gas selskaber bruger dem til udforskning

and construction.

og anlægsarbejde.

What we've built isn't unique.

Det vi har bygget er ikke unikt.

It's how we've built it that's really unique.

Det er måden vi har bygget det på, som er unikt.

So I want to give you a quick story of how it got started.

Lad mig give jeg historien om hvordan det startede.

So a few years ago, my friend Eric and I

For et par år siden besluttede min ven Eric og jeg

decided we wanted to explore this underwater cave

at vi ville udforske en undervandsgrotte

in the foothills of the Sierras.

ved foden af Sierra bjergene.

We had heard this story about lost gold

Vi havde hørt en historie om forsvundet guld

from a Gold Rush-era robbery, and we wanted to go up there.

fra et røveri i guldfeber tiden, og der ville vi gerne hen.

Unfortunately, we didn't have any money

Vi havde desværre ingen penge

and we didn't have any tools to do it.

og vi havde ingen værktøjer til at gøre det.

So Eric had an initial design idea for a robot,

Eric havde en design idé til en robot,

but we didn't have all the parts figured out,

men vi havde ikke alle delene til at bygge den,

so we did what anybody would do in our situation:

så vi gjorde hvad alle andre i vores situation ville have gjort:

we asked the Internet for help.

vi bad internettet om hjælp.

More specifically, we created this website,

Helt præcist, byggede vi en hjemmeside,

openROV.com, and shared our intentions and our plans

openROV.com, og delte vores tegninger og idéer.

For the first few months, it was just Eric and I

I de første par måneder var det kun Eric og jeg

talking back to each other on the forums,

som kommunikerede i foraene,

but pretty soon, we started to get feedback

men ret hurtig, begyndte vi at få tilbagemeldinger

from makers and hobbyists,

fra gør-det-selv folk og hobbybyggere,

and then actually professional ocean engineers

og også professionelle marineingeniører

who had some suggestions for what we should do.

som havde forslag til hvad vi kunne gøre.

We kept working on it. We learned a lot.

Vi fortsatte arbejdet. Vi lærte en masse.

We kept prototyping, and eventually,

Vi blev ved med at bygge prototyper, og til sidst,

we decided we wanted to go to the cave. We were ready.

besluttede vi at vi var klar til at tage ud til grotten.

So about that time, our little expedition became quite a story,

På det tidspunkt var vores lille ekspedition blevet en ret stor historie

and it got picked up in The New York Times.

og den blev taget op af The New York Times.

And we were pretty much just overwhelmed

Der var en overvældende interesse

with interest from people who wanted a kit

fra folk som ville have et byggesæt

that they could build this open ROV themselves.

så de selv kunne bygge en "open ROV".

So we decided to put the project on Kickstarter,

så vi besluttede at åbne et projekt på Kickstarter,

and when we did,

og da vi gjorde det,

we raised our funding goal in about two hours,

vi nåede vores finansieringsmål på to timer,

and all of a sudden, had this money to make these kits.

og nu havde vi pludselig råd til at lave byggesættene.

But then we had to learn how to make them.

Men vi var nød til at lære hvordan vi skulle lave dem.

I mean, we had to learn small batch manufacturing.

Vi var nød til at lære at producere et mindre parti.

So we quickly learned that our garage

Vi fandt hurtigt ud af at vores garage

was not big enough to hold our growing operation.

ikke var stor nok til vores projekt.

But we were able to do it, we got all the kits made,

Men det lykkedes os, vi fik alle byggesættene klar,

thanks a lot to TechShop, which was a big help to us,

stor tak til TechShop, som var en stor hjælp,

and we shipped these kits all over the world

og vi sendte byggesættene til alle dele af verden

just before Christmas of last year,

lige før jul sidste år,

so it was just a few months ago.

så ikke mere end at par måneder siden.

But we're already starting to get video

Men vi har allerede modtaget videoer

and photos back from all over the world,

og billeder tilbage fra hele verden,

including this shot from under the ice in Antarctica.

også dette klip optaget under isen på Antarktis.

We've also learned the penguins love robots.

Vi har også fundet ud af at pingviner elsker robotter.

(Laughter)

(Latter)

So we're still publishing all the designs online,

Vi deler stadig alle vores tegninger på nettet,

encouraging anyone to build these themselves.

opfordrer alle til at bygge dem selv.

That's the only way that we could have done this.

Det var den eneste måde vi kunne klare det.

By being open source, we've created

Ved at være open source, har vi skabt

this distributed R&D network,

et udviklings og design netværk,

and we're moving faster than any venture-backed counterpart.

og det går hurtigere end noget andet traditionelt finansieret projekt.

But the actual robot is really only half the story.

Men robotterne er faktisk kun halvdelen af historien.

The real potential, the long term potential,

Det sande potentiale, potentialet på lang sigt,

is with this community of DIY ocean explorers

ligger i det fællesskab af gør-det-selv marine forskere

that are forming all over the globe.

som vokser frem over hele kloden.

What can we discover

Hvad kan vi opdage

when there's thousands of these devices

med tusinder af disse robotter

roaming the seas?

svømmende rundt i havene?

So you're probably all wondering: the cave.

I tænker sikkert alle sammen på: grotten.

Did you find the gold?

Fandt I guldet?

Well, we didn't find any gold,

Vi fandt ikke noget guld,

but we decided that what we found was much more valuable.

men vi blev enige om at det vi fandt var meget mere værdifuldt.

It was the glimpse into a potential future

Det var et glimt af mulig fremtid

for ocean exploration.

indenfor marine forskning.

It's something that's not limited to the James Camerons of the world,

Det er ikke kun verdens James Cameron'er forundt,

but something that we're all participating in.

det er noget vi alle kan deltage i.

It's an underwater world

Det er en verden under vand

we're all exploring together.

vi alle udforsker sammen.

Thank you.

Tak.

(Applause)
