# The First Robot To Cross the Atlantic Ocean Underwater

#### kdawson posted more than 4 years ago | from pickens

Hugh Pickens writes "She was at sea for 221 days, alone, often in dangerous places, and usually out of touch. Most of the time she was out of contact underwater, moving slowly up and down to depths of 600 feet, safe from ships, nets, and storms. Her predecessor had disappeared on a similar trip, probably killed by a shark. 'She was a hero,' says Rutgers University oceanographer Scott Glenn after retrieving Scarlet Knight, the 7-foot-9-inch submersible robot from the stormy Atlantic off western Spain. An engineer working for the company that made the submersible said, 'We think this will just be a precursor, like Lindbergh's trip across the Atlantic. In a decade we think it will be commonplace to have roving fleets of these gliders making transoceanic trips.' The people responsible for building, funding, and flying Scarlet hope the end of the robot's successful voyage will mark a new beginning in ocean and climate research. From its position at each surfacing — when the glider surfaced and called home via an Iridium telephone parked in its tail — researchers could calculate the net effect of currents deep and shallow. After surface currents were measured, the scientists could then make inferences about what was happening deeper in the water column. Scarlet called home to upload data to researchers three times a day. 'When we have hundreds of them, or thousands of them, it will revolutionize how we can observe the oceans,' says Jerry L. Miller, a senior policy analyst at the White House Office of Science and Technology Policy, who accompanied the research team to Spain."

It's odd that everyone latched onto the "she" bit. The reason people are identified as hero's is not simply that they accomplish some feat, it's because they do so by persevering at great cost or difficulty. The robot had no choice, was completely incapable of making a selfish(or selfless) decision. It did exactly what it was supposed to do, within the parameters it was told to do so. It didn't care about the outcome either way. And of course, I for one welcome our sea traversing heroic female robot overlords.

Yes, except that the sea robot is entirely incapable of functioning outside of the parameters specifically set by it's operators. While the hype and glorification of past heroic events is surely interesting, the sea robot never at any time could say things like, "Fuck this I'm outta here" or, "JUST......ONE.......MORE........MILE/KILOMETER/HOGSHEAD/LEAGUE" nor could it ever contemplate it's place and others' perception of it should it fail or succeed. It at no time felt emotional pressure, real or perceived to impede or spur it to it's end. It just did. It was no more heroic(or less so for that matter) than your family car going 200,000 miles without an oil change instead of 20,000.

"I think it would need modification. Would it need to be made of some sort of stealth material (or shape), to avoid sonar detection? Or is it already small enough that it would be mistaken for debris?" I don't think his point is too far out. Right now, perhaps sonar is limited to a short range and fixed or limited range/purpose platforms like military subs, but if this aquaglider technology (UMV) develops in the manor suggested by the article, I don't see why the world governments wouldn't have thousands, perhaps millions of these (or similar configurations) out there with sonar rigs. They would autonomously operate and surface once a predetermined set of conditions were met, such as the detection of enemy subs, or small man made objects coming from known vectors of transit between drug making and drug loving countries. Maybe someone with some time on their hands could calculate whether or not, based on the range and accuracy of current sonar technology, it would be feasible to 'mine' the coast of Florida with these things and get something like a 15% or 20% coverage.

Of course it is feasible, as long as you don't care how much it costs.

Intercepting 20 or 30 percent of covert drug shipments is essentially worthless, so it is kind of hard to justify any cost to do so.

Intercepting 20 to 30% of covert drug shipments I would bet is about a 15 to 25% gain over our current stats, and would prove the feasability of such a system for a massive big brother of the ocean full scale deployment.

I'm sure that they'd like to; but I suspect that doing so will be considerably more challenging.

Pretty much all the UAVs currently in use are either in near-constant contact with HQ, receiving general instructions and sending back data, or (in the case of things like cruise missiles) are navigating themselves to some terminal location.

In the air, communication is about as easy as it is ever going to be. You have a decent shot at being able to talk point-to-point with nearby friendly ground forces, and you can always talk to a satellite if it comes to that, and most of our fancy RF tricks work just fine.

Underwater, communication is a huge pain. Fairly high energy, low bandwidth, hard to be inconspicuous about it. This pretty much kills the classic UAV deployment scenario. This doesn't stop you from using any fully autonomous behavior, and I'm sure that there are some clever things to be done there; but they will be much harder, and potentially more limited, than what you can do in the air.

#### Anonymous Coward | more than 4 years ago

This might fill a few gaps in the already running Argo fleet of passive probes http://en.wikipedia.org/wiki/Argo_(oceanography). These probes, of which there are already thousands around, are probably more cost efficient than something actively plowing through the ocean. Paying cargo ships to tow a probe behind them would probably work as well.

But then again the article mentions the U.S. Navy, so this is probably for something more than just harmless oceanography.

These are actually not "actively plowing through the ocean", these are more like smarter Argo probes. They sink/ascent, not in a vertical way but horizontally and using ocean currents to move forward, sortof like a bird using thermal convection.

the 7-foot-9-inch submersible robot from the stormy Atlantic off western Spain filled with cocaine .

In a decade we think it will be commonplace to have roving fleets of these gliders making transoceanic trips filled with cocaine .

At a price of $100,000 to$150,000 apiece (which is likely to drop once large-scale production begins), fleets of aquatic gliders outfitted with varying arrays of physical, chemical, acoustical and optical sensors promise to increase the store of data considerably at reasonable cost. The U.S. Navy has just ordered 150 to detect rogue aquatic gliders filled with cocaine .

Actually, you are wrong about that. Those submarines the drug cartels were creating started at about $1 million dollars to produce. So these automated subs would already be a fraction of the price and could be unmanned, an added bonus. Unmanned subs don't use product and don't require armed guards to protect them from the workers on the way there. Those costs would also go down in the future, so it could become much cheaper and safer to operate than manned systems. ### Re:Just a thought.....

I've been surprised we don't see autonomous drone aircraft being used for this purpose. It just isn't that hard. And of course, it's also a good way to get nuclear weapons over cities before detonating them, which is really where you want them to be for maximum damage, which is caused by the firestorm they start, not blast or radiation damage (just ask the good people of Nagasaki and Hiroshima if you disagree.) Despite the mystique of piloted vehicles, there is nothing very difficult, algorithmically, about running a sub or plane autonomously. The only reason we haven't done more of it yet is because we've only had sufficiently compact, powerful, computers for a decade or so. But I expect in the next decade we'll see a whole lot more of it, making nonsense of traditional notions of borders. Stealth technologies are just too simple for vehicles that have no mission profile except to get from point A to point B. They can fly as low as they want and as slow as they want, unlike stealth fighters and bombers. So anyone who claims these things will be detectable is taking a whole lot on faith, whereas their existence is a matter of fact. How the technological fight between detection and penetration capabilities turns out will have a large effect on the future viability of nation-states. Unlike idiotic movies (Terminator Salvation and later films in the Matrix trilogy come to mind) the real risk from autonomous machines is not that they will go rogue and take over the world, but that stupid human cowards will use them to randomly destroy stuff at a sufficiently high rate to endanger the large-scale structures that sustain what we are wont to call civilization. ### Re:Just a thought.....

(3, Interesting) This comment was hidden based on your threshold setting. #### radtea | more than 4 years ago Maybe we could call them buzzbombs or cruise missiles or intercontinental ballistic missiles or something. Buzzbombs and intercontinental ballistic missiles don't make much use of computational intelligence. Cruise missiles are similar to what I'm talking about, although the Wikipedia entry on them makes the useful point that they are distinct from UAVs because the warhead is integrated into the missile, they are always destroyed by successful completion of their mission, and they are never used for recon. That aside, my point--which I guess I didn't make sufficiently clear--is that I'm talking about seeing bomb-carrying (and drug-carrying) UAVs in the hands of non-governmental forces. It is odd that we haven't, given how cheaply it could be done so long as one deviates from the integrated-systems design of cruise missiles, and avoids the dumb-trajectory aspects of buzz-bombs and ICBMs. In fact, so long as one builds autonomous general-purpose UAVs the cost is very low. Buying and modifying a typical light sport aircraft with a carrying capacity of a few hundred kg and a range of a thousand kilometers would run less than$100k, based on used aircraft prices.

That's a lot of cocaine, and a plane or two like that loaded with C4 and ball-bearings dropping into a random American city every couple of nights would create a huge amount of panic, which would probably result in the US invading Peru or someplace, just for the look of the thing. Admittedly the range would have to be increased to be able to reach the US from Saudia Arabia, which is where attacks like this would obviously originate, but that's a relatively minor technical problem given current materials and engine technologies.

These things are a terrorist's dream, and we've known since the '80's we were headed this way. Donald Kingsbury's novel "The Moon Goddess and the Son" describes the possibility, and it was published in '85 or so. Ergo, it should come as no surprise to anyone when the first use of UAVs by non-governmental criminal organizations comes to light.

Of course, any that you listed are kinda one-use weapons (since they kinda explode at the end of their trip), but that's the biggest difference between a UAV and a cruise missile. :)

The V-1 and cruise missile actually fly. The ICBM's were, well, ballistic. You still had to maintain a course on the way up to the apogee. Then gravity took care of the rest.

You are creating problems that don't exist, and are quite easily solved. Far from ridiculous, my friend.

The right hands is pretty simple. Only the right hands would know the GPS coordinates and correct time to look for the thing in the first place. Submerges a couple hundred feet? Yeah, that makes it really easy for the wrong hands to find. Moves autonomously? Can move between several pick up points depending on the time and date? Yeah... it's not going to be that easy to find if you don't know where you are looking first.

We got cocaine in it, so why not C4? Even if you accidentally come across one you better have the right security codes to open it up, or Keanu Reeves handy with some wire cutters to defuse the bomb. The governments of course would just blow it up, which would make it really interesting for the fish in the area :)

Deals? Currency exchanges? You are making the assumption that this is outside of the organization. Inter-organizational transfers would not be that complicated and all of the knowledge about where the automated subs are remains within trusted organization members.

Even deals between distributors and suppliers would not be that difficult either. Supplier gets coordinates, times, and security codes to pick up money from one spot and then delivers the coordinates, times, and security codes to the distributor so they get the product. If the deal does not occur within a certain time period, the automated sub returns to the supplier for "refueling" (if even necessary) and new instructions. Assuming that is even necessary. It might be possible for the automated sub to receive instructions remotely which means they could just be in "hover" mode off the coast.

As for proof, you are speaking to levels of trust and experience between the groups running the drug trade right now. That problem exists regardless of the technology and mediums in which you are transporting the product and currencies.

I would imagine that the first deal would require a bit of an arms length type transaction or escrow with a trusted 3rd party, but after that it would probably run pretty smoothly.

The information regarding the GPS coordinates, times, and security codes would remain with trusted individuals in the two organizations and only travel through trusted and vetted channels.

Your problems are really quite easily solved.

That sounds more like digg.

speaking of dropped the ball... I think that the scarlet knights is the rutgers basketball team. And I don't think they're very good either. Maybe they should start practicing rather than building robots...

Maybe we slashdotters can work together to remake the lyrics to Yellow Submarine for it. Draft 1:

In the town, where I was born
We made a bot, which sailed to sea
And it radioed, us of its life
In the land, of submarines

So it sailed, without the sun
Till it found, the sea of green
And it glided, beneath the waves
It's our yellow, bot submarine

We all monitor the yellow submarine
Yellow submarine, yellow submarine
We all monitor the yellow submarine
Yellow submarine, yellow submarine ...

what makes it a robot: how autonomous does a robot have to be?

#### dtmos | more than 4 years ago

Just to amplify the point, in August 2003 the Trans-Atlantic Model (TAM) project, led by modeling legend Maynard Hill, sent a model airplane from Cape Spear, NF, Canada to Mannin Beach, Ireland, a flight of 3030 km lasting 38h 52 min 19 sec. The craft was radio-controlled during takeoff and landing, but used a GPS-based autopilot during the remainder of the flight. Surely, this is equivalent to launching and recovering the autonomous Scarlet Knight submarine manually at sea.

The WP article says very little about the batteries. Did they pack sufficient juice for the entire trans-Atlantic trip, or was there some hydrodynamic principle used to recharge the batteries?

#### swillden | more than 4 years ago

A previous /. article quite some time ago talked about the invention of these underwater gliders and how they could travel enormous distances on very, very little power. Basically they operate by making small changes in buoyancy. When slightly heavier than the water around them, they sink, but the water flowing over their wings drives them forward for significant distance for every meter they descend. Then they reverse it to become slightly lighter than the water, rising and again moving forward. Because this takes so little energy, they can travel thousands of kilometers on internal batteries.

However, there are other variants that don't use stored energy for propulsion at all, instead making use of temperature differentials to change their buoyancy. In deep, cold water they become positively buoyant, but when they're warmed by surface water they become negatively buoyant.

The article isn't very clear, but I don't think this one is thermally-powered.

New here? It is a glider, changing bouyancy to go up and down, and using the lift of it's wings to provide horizontal motion. I understand it has a small prop to generate power for the electronics and hydraulics.

Clearly you're not new here, because you didn't RTFA, didja? Nowhere in the article does it mention a propeller or anything else to recharge the batteries. I was looking for such a mention, because that was the only thing that motivated me to even read the article myself. The means of locomotion was certainly explained well enough, but that wasn't news to me. I was askin' because it wasn't described at all, not because I'm new here.

### The Wave Glider could probably make that trip (5, Interesting)

This comment was hidden based on your threshold setting.

#### Animats | more than 4 years ago

Wave Gliders, from Liquid Robotics, have already made autonomous trips from Hawaii to California. They sent one up the coast from California to Alaska and back. They could probably do the Atlantic, but they're based in Hawaii, so they tend to work the Pacific Ocean.

Those are cute little machines. There are two parts; the floater, which looks like a surfboard with solar panels, and the glider, which is tethered to the floater by a cable of about 10 meters. The gilder has elevator-like flaps, which are spring-loaded to return to center. As wave action moves the floater up, the pull on the cable pulls the glider upward too, which forces the flaps down. The water pushing against the flaps pushes the glider forward, towing the floater. On down waves, the glider sinks further, the flaps are pushed up, and in that position, the falling glider then pulls the floater forward.

Wave Gliders have only one powered moving part, the rudder. That's on the glider. Up top, on the floater, there's a GPS, a compass, an Iridium transceiver, and a microcontroller. This is enough to keep the Wave Glider on course. It normally stays within 50m of the desired track, and averages about 1 knot; more in storms, less on calm days. Storms don't bother it too much; the glider pulls the floater through big waves, like a surfboard.

It only takes a few watts to run the electronics and keep the Wave Glider on course. The solar panels and a rechargeable battery provide that. So there's nothing to run out of. It just keeps going.

Once we get a few decades of accurate water movement records from every significant body of water well surely know enough to say that we are experiencing man made current slowing due to boat propellers, and we may all be dead within 50 years if we don't give another multiple billion dollar payment to the worlds most oppresive regimes. Maybe we can have those talks in Copenhagen too. Yep that would be awesome!
