SCOUT TRANSATLANTIC AUTONOMOUS ROBOT BOAT RECORD ATTEMPT 15 DAYS 2013

Following on from the Scout Atlantic bash in 2013, in 2020, a team comprising Promare, IBM, and many other technology partners, decided to attempt to cross the Atlantic against the prevailing winds and currents. They set out to build a 100ft craft named Mayflower Autonomous Ship (MAS) for launch and an attempt, aiming for the 400th anniversary of the Pilgrim Fathers journey starting on the 6th of September 1620.

They never made that date, partly due to Covid 19, but did manage to get a hull in the water for the ceremonies in Plymouth, Devon in 2020. On the 15th June 2021, the unmanned craft departed from Plymouth in England, aiming for Plymouth, Massachusetts, USA. You can follow the journey on their blog: https://mas400.com/dashboard

MAS 400 - The fully autonomous trimaran Setting off from Plymouth, England on the 15th June 2021. There are solar panels, that presumably add to the diesel-electric setup. The idea is to be COLREGs compliant with a self learning program, as such vessels build a database. Much the same as with the current bevy of self-driving robotaxis and robotracks. The question is therefore, will ships beat trucks to the autonomous punch?

SPECTRUM IEEE 27 September 2013 - Robotic Boat Hits 1000-Mile Mark in Transatlantic Crossing

“Scout,” a 4-meter-long autonomous boat built by a group of young DIYers, is attempting to cross the Atlantic Ocean. It is traveling from Rhode Island, where it launched on 24 August, to Spain, where all being well it will arrive in a few months’ time.

Scout has now gone about 1000 miles (1600 kilometers) of its planned 3700-mile (5900 kilometer) journey. Should it complete this voyage successfully, its passage will arguably belong in the history books.

I say “arguably,” because it won’t be the first time a robotic vessel has crossed the Atlantic: Scarlet Knight, a sea-going robot fielded by researchers at Rutgers University, did that in 2009. But Scout stands to beat out Scarlet in my mind, for several reasons. You see, Scout would be the first robotic surface vessel to make this crossing. Scarlet was what is known as an oceanographic glider, which porpoises up and down, spending most of the time at significant depth.

Okay, maybe the distinction between a surface vessel and an oceanographic glider is too fine for the typical landlubbing roboticist to care about. But there are other reasons to disqualify Scarlet from the record book of autonomous Atlantic Ocean crossings. For one, Scarlet was launched from a ship about 50 miles offshore of
New Jersey. And it was recovered by another ship far offshore from Spain. So it didn’t really make a continent-to-continent voyage at all.

If this sounds like a trivial point, then you’ve probably not done much blue-water sailing. Out in the middle of the ocean, there’s not much to hit. Close to shore, however, you’re in the shipping lanes, fishing boats are zigzagging around deploying nets or hauling them in, and recreational traffic increases enormously. If you’re sailing into a busy port, it can feel like you’re dodging giants in the final hours. So the fact that Scarlet didn’t have to endure the most risky parts of a transatlantic journey is significant.

If that’s not good enough for you, consider this: Scarlet could be remotely controlled. Indeed, soon after Scarlet put to sea, it became clear that there was a problem, one that was corrected by uploading some new parameters by radio. (Spectrum’s coverage of Scarlet describes this episode.) Now how autonomous is that?

Also, Scarlet required a pit stop. Off the Azores, technicians from Rutgers caught up with Scarlet to scrape barnacles off its hull. They did that in the water rather bringing it aboard ship. So technically, the glider’s journey was uninterrupted. Technically.

Scout is shooting for a transatlantic record under a different set of rules. It was carried off the beach and into the water by two guys on their backs—and only far enough out so that it’s keel would clear the bottom. Scout sends telemetry updates three times an hour using an Iridium transmitter, but no new instructions or parameters can be sent to it. It must navigate autonomously.

Completely autonomous operation means pesky little problems like that one that dogged Scarlet initially can’t be fixed after the fact, making the enterprise that much more difficult. The Scout team, too, realized their boat had a problem soon after it set off - a software glitch caused it to ignore many of the offshore waypoints that had been programmed in (the bug was in code intended to prevent the boat from backtracking should currents push it east of a given waypoint). But Scout got off okay and is still cruising toward Spain. The team is pretty sure that it is headed for a waypoint that lies about 150 miles west of its final destination, Sanlúcar de Barrameda.

Although the construction of Scout’s hull is somewhat high-tech carbon fiber sandwiching Divinycell foam, the rest of the boat is comparatively simple. Solar panels mounted on the top of the hull charge a lithium-iron-phosphate battery, which in turn powers an ordinary trolling motor attached to the bottom of the hull. (In good DIY style, the motor was purchased at Dick’s Sporting Goods.) Under ideal conditions, the battery will gain sufficient charge during the day to power the boat’s motor throughout the following night. Under less than ideal conditions, the motor shuts down when battery voltage gets too low, and the boat just drifts until it can get charged up again.

Scout is plenty seaworthy even when it’s not under power, and there’s nobody to feed or entertain, so drifting with the waves for a few days is no big deal. Even raging storms shouldn’t be a problem: An angled upper deck and a hefty amount of lead on the bottom of the keel ensure that the boat will quickly right itself if it gets flipped over.

Scout’s builders also included a couple of simple fail-safe features. One is that the onboard computer (an Arduino, of course!) gets automatically reset every few hours. This should protect it from freezing up should there be a memory leak or other subtle problem with its code.

The other clever measure they took was to program the boat to stop and back up a little ways every five hours. Their thinking was that this maneuver could help to clear the keel and motor of any flotsam it might have picked up. They say that they tested this technique and that it works pretty well.

I hope so. In my estimation, Scout’s greatest challenge will come from encounters with marine garbage, in particular stray bits of fishing line, which could easily foul the prop. Sargassum, a common floating seaweed, could also cause trouble.

That Scout has made it more that a quarter of the way across is encouraging, though. As a great admirer of ambitious DIY endeavors, I will continue to monitor its progress across the increasingly rough North Atlantic over the next few months and cheer the little boat onward through wind and waves from the comfort of my warm and dry office.
