So this video was taken

Aquest vídeo es va filmar

at Aquarius undersea laboratory

al laboratori subaquàtic Aquarius,

four miles off the coast of Key Largo,

a 6 quilòmetres de la costa de Cayo,

about 60 feet below the surface.

uns 20 metres sota l'aigua.

NASA uses this extreme environment

La NASA fa servir aquest ambient extrem

to train astronauts and aquanauts,

per entrenar astronautes i aiguanautes,

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

i l'any passat, ens van convidar a fer-hi un volt.

All the footage was taken from our open ROV,

Tot es va filmar des del nostre OpenROV

which is a robot that we built in our garage.

que és un robot que vam construir al nostre garatge.

So ROV stands for Remote Operated Vehicle,

ROV són les sigles (angleses) de vehicle amb control remot,

which in our case means our little robot

que, en el nostre cas, vol dir que el nostre robotet

sends live video

envia imatges en directe

across that ultra-thin tether

per aquest nus ultra prim

back to the computer topside.

cap a l'ordinador a la superfície.

It's open source, meaning we publish

Té codi obert, és a dir que publiquem

and share all of our design files

i compartim tots els arxius de disseny

and all of our code online,

i tot el nostre codi a la xarxa

allowing anyone to modify

perquè qualsevol pugui modificar

or improve or change the design.

o millorar, o canviar el disseny.

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

La majoria de components són comprades en botigues,

and costs about 1,000 times cheaper

i té un cost uns 1000 vegades més barat

than the ROVs James Cameron used

que els ROVs que James Cameron va usar

to explore the Titanic.

per explorar el Titànic.

So ROVs aren't new.

Així que els ROVs no són una novetat,

They've been around for decades.

fa dècades que existeixen:

Scientists use ROVs to explore the oceans.

els científics els fan servir per explorar els oceans;

Oil and gas companies use them for exploration

les petrolieres els fan servir per explorar

and construction.

i construir.

What we've built isn't unique.

El que hem construït no és únic.

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

És COM ho hem fet, que és únic.

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

Us vull explicar ben ràpid com va començar.

So a few years ago, my friend Eric and I

Fa pocs anys, el meu amic Eric i jo

decided we wanted to explore this underwater cave

vam decidir que volíem explorar una cova submarina

in the foothills of the Sierras.

a la falda de les Sierras.

We had heard this story about lost gold

Hi havia una llegenda sobre or perdut

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

d'un robatori durant la Febre de l'Or, i volíem anar-hi.

Unfortunately, we didn't have any money

Desgràciadament, no teníem diners,

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

ni eines per fer-ho.

So Eric had an initial design idea for a robot,

L'Eric havia fet un disseny inicial per a un robot,

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

però no sabíem com fer cadascuna de les parts,

so we did what anybody would do in our situation:

així que vam fer el que faria qualsevol a la nostra situació:

we asked the Internet for help.

vam demanar ajuda a internet.

More specifically, we created this website,

Concretament, vam crear aquesta web,

openROV.com, and shared our intentions and our plans

openROV.com, on vam explicar les nostres intencions i plans.

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

Durant els primers mesos, només hi érem l'Eric i jo,

talking back to each other on the forums,

parlant entre nosaltres als fòrums,

but pretty soon, we started to get feedback

però ben aviat, vam començar a rebre comentaris

from makers and hobbyists,

de fabricants i amateurs,

and then actually professional ocean engineers

i després de veritables enginyers navals

who had some suggestions for what we should do.

que ens feien suggeriments sobre què havíem de fer.

We kept working on it. We learned a lot.

Vam continuar-hi treballant. Vam aprendre moltes coses.

We kept prototyping, and eventually,

Vam seguir construint prototips i, al final,

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

vam decidir que volíem anar a la cova. Estàvem preparats.

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

En aquell moment, la nostra petita expedició ja s'havia convertit en notícia

and it got picked up in The New York Times.

i ens la va cobrir la New York Times.

And we were pretty much just overwhelmed

Nosaltres estàvem més aviat aclaparats

with interest from people who wanted a kit

per l'interès de la gent que volia un kit

that they could build this open ROV themselves.

a partir del qual poguessin construir el seu propi OpenROV.

So we decided to put the project on Kickstarter,

Vam decidir publicar el projecte a Kickstarter,

and when we did,

i en fer-ho,

we raised our funding goal in about two hours,

vam arribar a l'objectiu que teníem en dues hores,

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

i de cop i volta, teníem prou diners per fer els kits.

But then we had to learn how to make them.

Però havíem d'aprendre com fer-los.

I mean, we had to learn small batch manufacturing.

És a dir, havíem d'aprendre a manufacturar petits lots.

So we quickly learned that our garage

No vam tardar gaire en adonar-nos que el nostre garatge

was not big enough to hold our growing operation.

no era prou gran per encabir el nou negoci.

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

Però ho vam aconseguir, vam fer tots els kits,

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

moltes gràcies a TechShop, que ens va ajudar molt,

and we shipped these kits all over the world

i vam enviar els kits per tot el món,

just before Christmas of last year,

just abans del Nadal passat,

so it was just a few months ago.

és a dir, fa només uns mesos.

But we're already starting to get video

Però ja comencem a rebre vídeos

and photos back from all over the world,

i fotos des de tot arreu del món,

including this shot from under the ice in Antarctica.

com ara aquesta imatge, des de sota el gel de l'Antàrtida.

We've also learned the penguins love robots.

També hem après que els pingüins adoren els robots.

(Laughter)

(Riure)

So we're still publishing all the designs online,

Així que seguim pujant tots els dissenys a internet,

encouraging anyone to build these themselves.

animant a tothom a construir-se'n un.

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

És l'única manera com ho podríem haver fet.

By being open source, we've created

Tenir codi obert ens ha permès crear

this distributed R&D network,

aquesta xarxa estesa d'I+D,

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

i ens movem més ràpid que qualsevol competidor amb inversors.

But the actual robot is really only half the story.

Però el robot en si és només la meitat de la història.

The real potential, the long term potential,

El potencial real, el potencial a llarg termini,

is with this community of DIY ocean explorers

és en aquesta comunitat d'exploradors de l'oceà que s'ho fan ells mateixos

that are forming all over the globe.

que s'està formant arreu del planeta.

What can we discover

Què podem arribar a descobrir,

when there's thousands of these devices

quan hi ha milers d'aparellets d'aquests

roaming the seas?

passejant pels mars?

So you're probably all wondering: the cave.

Probablement us ho pregunteu: la cova.

Did you find the gold?

Vau trobar l'or?

Well, we didn't find any gold,

Bé, no en vam trobar pas,

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

però vam decidir que el que vam trobar era molt més valuós.

It was the glimpse into a potential future

Va ser entreveure el futur potencial

for ocean exploration.

de l'exploració oceànica.

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

No és una cosa limitada als James Camerons del món,

but something that we're all participating in.

sinó que tots hi participem.

It's an underwater world

És un món submarí

we're all exploring together.

que explorem tots junts.

Thank you.

Gràcies.

(Applause)
