Denne video er optaget ved Aquarius undervands laboratorium 6,5 km. ud for Key Largos kyst omkring 20 m. under havets overflade. NASA bruger dette ekstreme miljø til at træne astronauter og aquanauter, og sidste år, blev vi inviteret med. Alle disse optagelse er fra vores "open ROV", som er en robot vi har bygget i vores garage.
So this video was taken at Aquarius undersea laboratory four miles off the coast of Key Largo, about 60 feet below the surface. NASA uses this extreme environment to train astronauts and aquanauts, and last year, they invited us along for the ride. All the footage was taken from our open ROV, which is a robot that we built in our garage.
ROV står for Remote Operated Vehicle, (fjernstyret fartøj) Vores lille robot sender billeder direkte via en ultra tynd ledning tilbage til computeren oppe på overfladen. Den er open source (åben kilde), hvilket betyder at alle vores design filer al vores kode er tilgængelig på nettet, så alle kan justere eller forbedre eller ændre designet. Den er bygget af let tilgængelige dele koster en promille af hvad den ROV som James Cameron brugte til at udforske Titanic. ROV'er er ikke en ny ting. De har været brugt i årtier. forskere bruger ROV'er til at udforske havene. Olie og gas selskaber bruger dem til udforskning og anlægsarbejde. Det vi har bygget er ikke unikt. Det er måden vi har bygget det på, som er unikt.
So ROV stands for Remote Operated Vehicle, which in our case means our little robot sends live video across that ultra-thin tether back to the computer topside. It's open source, meaning we publish and share all of our design files and all of our code online, allowing anyone to modify or improve or change the design. It's built with mostly off-the-shelf parts and costs about 1,000 times cheaper than the ROVs James Cameron used to explore the Titanic. So ROVs aren't new. They've been around for decades. Scientists use ROVs to explore the oceans. Oil and gas companies use them for exploration and construction. What we've built isn't unique. It's how we've built it that's really unique.
Lad mig give jeg historien om hvordan det startede. For et par år siden besluttede min ven Eric og jeg at vi ville udforske en undervandsgrotte ved foden af Sierra bjergene. Vi havde hørt en historie om forsvundet guld fra et røveri i guldfeber tiden, og der ville vi gerne hen. Vi havde desværre ingen penge og vi havde ingen værktøjer til at gøre det. Eric havde en design idé til en robot, men vi havde ikke alle delene til at bygge den, så vi gjorde hvad alle andre i vores situation ville have gjort: vi bad internettet om hjælp. Helt præcist, byggede vi en hjemmeside, openROV.com, og delte vores tegninger og idéer. I de første par måneder var det kun Eric og jeg som kommunikerede i foraene, men ret hurtig, begyndte vi at få tilbagemeldinger fra gør-det-selv folk og hobbybyggere, og også professionelle marineingeniører som havde forslag til hvad vi kunne gøre. Vi fortsatte arbejdet. Vi lærte en masse. Vi blev ved med at bygge prototyper, og til sidst, besluttede vi at vi var klar til at tage ud til grotten.
So I want to give you a quick story of how it got started. So a few years ago, my friend Eric and I decided we wanted to explore this underwater cave in the foothills of the Sierras. We had heard this story about lost gold from a Gold Rush-era robbery, and we wanted to go up there. Unfortunately, we didn't have any money and we didn't have any tools to do it. So Eric had an initial design idea for a robot, but we didn't have all the parts figured out, so we did what anybody would do in our situation: we asked the Internet for help. More specifically, we created this website, openROV.com, and shared our intentions and our plans For the first few months, it was just Eric and I talking back to each other on the forums, but pretty soon, we started to get feedback from makers and hobbyists, and then actually professional ocean engineers who had some suggestions for what we should do. We kept working on it. We learned a lot. We kept prototyping, and eventually, we decided we wanted to go to the cave. We were ready.
På det tidspunkt var vores lille ekspedition blevet en ret stor historie og den blev taget op af The New York Times. Der var en overvældende interesse fra folk som ville have et byggesæt så de selv kunne bygge en "open ROV".
So about that time, our little expedition became quite a story, and it got picked up in The New York Times. And we were pretty much just overwhelmed with interest from people who wanted a kit that they could build this open ROV themselves.
så vi besluttede at åbne et projekt på Kickstarter, og da vi gjorde det, vi nåede vores finansieringsmål på to timer, og nu havde vi pludselig råd til at lave byggesættene. Men vi var nød til at lære hvordan vi skulle lave dem. Vi var nød til at lære at producere et mindre parti. Vi fandt hurtigt ud af at vores garage ikke var stor nok til vores projekt. Men det lykkedes os, vi fik alle byggesættene klar, stor tak til TechShop, som var en stor hjælp, og vi sendte byggesættene til alle dele af verden lige før jul sidste år, så ikke mere end at par måneder siden. Men vi har allerede modtaget videoer og billeder tilbage fra hele verden, også dette klip optaget under isen på Antarktis. Vi har også fundet ud af at pingviner elsker robotter. (Latter)
So we decided to put the project on Kickstarter, and when we did, we raised our funding goal in about two hours, and all of a sudden, had this money to make these kits. But then we had to learn how to make them. I mean, we had to learn small batch manufacturing. So we quickly learned that our garage was not big enough to hold our growing operation. But we were able to do it, we got all the kits made, thanks a lot to TechShop, which was a big help to us, and we shipped these kits all over the world just before Christmas of last year, so it was just a few months ago. But we're already starting to get video and photos back from all over the world, including this shot from under the ice in Antarctica. We've also learned the penguins love robots. (Laughter)
Vi deler stadig alle vores tegninger på nettet, opfordrer alle til at bygge dem selv. Det var den eneste måde vi kunne klare det. Ved at være open source, har vi skabt et udviklings og design netværk, og det går hurtigere end noget andet traditionelt finansieret projekt. Men robotterne er faktisk kun halvdelen af historien. Det sande potentiale, potentialet på lang sigt, ligger i det fællesskab af gør-det-selv marine forskere som vokser frem over hele kloden. Hvad kan vi opdage med tusinder af disse robotter svømmende rundt i havene?
So we're still publishing all the designs online, encouraging anyone to build these themselves. That's the only way that we could have done this. By being open source, we've created this distributed R&D network, and we're moving faster than any venture-backed counterpart. But the actual robot is really only half the story. The real potential, the long term potential, is with this community of DIY ocean explorers that are forming all over the globe. What can we discover when there's thousands of these devices roaming the seas?
I tænker sikkert alle sammen på: grotten. Fandt I guldet? Vi fandt ikke noget guld, men vi blev enige om at det vi fandt var meget mere værdifuldt. Det var et glimt af mulig fremtid indenfor marine forskning. Det er ikke kun verdens James Cameron'er forundt, det er noget vi alle kan deltage i. Det er en verden under vand vi alle udforsker sammen.
So you're probably all wondering: the cave. Did you find the gold? Well, we didn't find any gold, but we decided that what we found was much more valuable. It was the glimpse into a potential future for ocean exploration. It's something that's not limited to the James Camerons of the world, but something that we're all participating in. It's an underwater world we're all exploring together.
Tak.
Thank you.
