8th Annual AUV Competition Results

Robotics 137

An anonymous reader writes "This weekend the 8th Annual Autonomous Underwater Vehicle (AUV) Competition was held in San Diego. This year teams were challenged to complete three tasks including finding a docking station, inspecting a pipeline, and surfacing in a recovery zone marked by an acoustic pinger. Teams from MIT, Cornell, Duke and sixteen others competed for the grand prize. After an intense final round, the University of Florida's Team SubjuGator dethroned MIT and walked away with the victory. Interestingly, the UF team ran Windows XP on their embedded computer."

XP Embedded (5, Interesting)

malelder (414533) | about 9 years ago | (#13287290)

The embedded version of XP is actually quite nice. I helped configure a version that runs some navigation equipment on airplanes. Having main-stream support for the hardware, and then ONLY having to put in that specific support, plus the support for the basic applications it will use keeps it quite stable. It's also really small when done correctly...we run ours off of a 32meg thumbdrive.

Heh (; well, being that this is Slashdot, and that most people feel Windows OS's are zero stable, I used "quite stable" to imply that I've never had a problem with our implementation of it...but I'm damn good at what I do (;

And I was a little vague, it doesn't navigate the plane (no computerized Chewbacca yet), but collects information on the location of the plane in time and space, and relays it back to a central database (this is required for all airlines and is usually done by paper and pencil...so this just automates a lot of that info gathering). It's neat stuff.

>>It's also really small when done correctly...we run ours off of a 32meg thumbdrive. This isn't especially small in the embedded space. I used uCLinux on a Motorola Dragnoball a few years ago, and the entire system ran quite well on a uCSimm with 8 MB of dynamic memory and 8MB of flash including ethernet and tcp/ip. Things like QNX and Windriver can be tailored to run in even less space. Of course, it depends on the hardware architecture you are running on, and especially on what you are trying to do.

Yes, Amador Valley is where I went to highschool, and my Junior year the UAV team beat all the other competitors, including MIT. This year they placed 5th, still very respectable for a high school with an (assumably) much smaller budget than these colleges. Not absolutely positive, but the year that Amador won, the budget was $3k. Funny thing is that although the UAV competition is prestigious, even when we won 1st almost nobody outside of the sciences on campus noticed.

Found: duck tape

Processing...

Multiple possibilities found...

1. To decrease height rapidly because a sticky film has been thrown in your direction ("Duck! Tape!")

2. An adhesive strip that is used to attach together two or more types of water fowl

3. A far-too-common misspelling for duct tape (see: their/they're, to/too, your/you're)

The most likely cause is (3). Because of the nature of the original message (submarine, thus water-based), it is possible that the original message is in reference to (2). This is, however, unlikely.

duct tape vs duck tape

please wiki my friend...

Duct tape (originally known as duck tape) is a strong, fabric-based, multi-purpose adhesive tape, usually silver in color, although many other colors, including transparent, are also available, and is usually 2 inches (50 mm) wide. It was originally developed during World War II in 1942 as a waterproof sealing tape for ammunition casings. Permacel, then a division of Johnson & Johnson, used a rubber-based adhesive to help the tape resist water and a fabric backing to facilitate ripping. Because of these properties, it was also used to quickly repair military equipment, including jeeps, guns, and aircraft.

They have had those for years. MIT's biggest problem seems to be that they try to make everything overly complex. My first year at this competition (I was on Amador Valley's Team) they custom built new thrusters at 2k each and they were having all sorts of problems with them. I think it ended up basically costing them the competition although I wasn't on their team so I wouldn't know.

Uptime? Downtime? (1, Offtopic)

erroneus (253617) | about 9 years ago | (#13287526)

not sure which would be the correct term since this is a submersible vehicle after all. In any case, what is the MTBF on a running system? What happens when a hardware component fails or fails to respond?

It would be interesting to see details such as these.

We take for granted that when devices are powered by Linux that it behaves well. We take for granted that Windows does not. It's a bit unfair to keep assuming Windows will cause failures in any system but it was a reputation that was undeniably earned.

The idea of rebooting as a solution essentially started with Windows as far as I can see. A computer runs by performing a series of instructions. If, after running a series long enough that the program code or the data it acts on becomes corrupt or unusable (ruling out hardware failure of course) then there is a problem with the code that should be FIXED. Rebooting is only a measure to be taken when debugging a system, not repairing it. Somehow, thanks to Microsoft (IMHO) CTRL-ALT-DELETE is thought of as a means of fixing a problem. I come from a different world where rebooting means you just installed a new kernel and want to run it.

Actually, it came about because what I describe. It used to be a big secret until helpdesks started using it in their telephone-scripts [e.g. 1) insert floppy, 2) ctrl-alt-delete, 3) install]. The autoexec.bat method was a lot easier than having to explain "type A:\install.bat" to a customer. The guy behind it once talked about the history of it, and he covered this. He also thanked Bill Gates (who was present) for making it uber-famous. There's an mpg of this interview floating about somewhere, Bill was not amused at the blue-screen dig tho!

Even with advanced submarine signal processing these are very very hard to find and you can't put submarine nets around a whole continent.

Autonomous vehicles of any kind, sea, air or land are a technological mixed blessing with massive potential for bad use.

Drug smugglers don't need things like subs. The illegal drugs trade is the third biggest industry on the planet. That is, there are more drugs entering your country each week than many other consumables e.g. livestock, clothing. They aren't getting smuggled in under toupees or in people stomachs to satify those volumes. Just need to know a "supportive" customs official or intelligence agent, who will allow the cargo through unchecked. Makes a lot of money and helps you fund terrorist groups in countries where you feel you could make a little more money in other industries with a change of goverment! ;-)

If she gets busted, you're out less than the cost of a minicrimsub, you don't tip off the G-men to your methodology, and there are fewer material clues pointing back to your secret base under the crater of the extinct volcano.

How does one find out what the various teams did wrong to see why they placed where they did? It would be interesting to see where the various schools made mistakes, but I don't see any such information on the website. My alma mater (NCSU) finished poorly in 18th place! At least we weren't last...

My thoughts (On Amador Team) (3, Informative)

Hex4def6 (538820) | about 9 years ago | (#13288081)

I agree, and what I found was simply by talking to the teams.. I really think AUVAI should have an "after the fact" type page, with comments by different teams as to why they did so well / bad.

You can read on the AUVAI webpage the breakdown of points... if one copmletes the mission, all the others are basically irrelevants (such as static judging). However, since so many people were not able to complete the mission, these points become important for seperating out the bottom of the stack. Basically, teams 1-4 where the only teams able to complete part of the mission (I don't believe anyone was able to complete the entire mission).

I think as regards problems... I know for us it was our PC104 stack getting destroyed by some short in the endcap... For Univ of Victoria, they had communication troubles between their custom PIC boards, and didn't have the original guy on their team who made them anymore (apparently he dumped the team 2 days before the competition, and didn't return their emails). For Rhode Island, I know that their bouyancy system, which is kinda neat actually (they use a compression cylinder to change their bouyancy) somehow leaked, and flouded their tube. For the rest of the teams, I'm not so sure, but they were similar problems. I think everyone suffers from reliability issues, not technical sophistication problems -- everyone has these amazing technologies that are all very impressive. The problem comes with the intergration of all these components into one vehicle.

Hi, My roommate is on the NCSU team, and I can shed some light on their status at the competition. From my understanding the NCSU's team could do most everything the competition needed. It had acoustics, image detection, the works. Their thrusters however stopped working at the last moment. It worked fine up until the point where they put it in the water for the qualifying round. When it was put in the water, the thrusters failed and nothing happened. They only got back yesterday and are not completely sure what happened, but they believe it had something to do with water in the pool getting into their cables. They had tested extensively in chlorinated pools, but not in the fresh water stuff that they encountered at the competition. My roommate was actually disappointed at all the entries and the competition itself. None did all that well from what it sounded like, and according to him at least one of the teams that came without a robot scored higher than they did!

Hehehe! Being from ETS (and in an engineering team myself, our school's solar car team), had to bring this up, ETS too unclassed MIT :) (by finishing 2nd)

Go S.O.N.I.A. [etsmtl.ca] ! Good job guys!

"It appears you're designing an Autonomous Underwater Vehicle. Would you like me to:
A. Lose control of the rudder and drive in circles.
B. Inexplicably blow all the ballast tanks and sink silently to the bottom.
C. Work marginally well for thirty minutes before ceasing all functions and requiring online registration."

I believe that in B.) - blowing all of the ballast tanks would make it shoot to the surface - given that the sub would no longer have the weight of the water inside of it to make it neutrally bouyant.

MS donates a lot of money/equipment (1)

vijayiyer (728590) | about 9 years ago | (#13287794)

MS is definitely increasing their influence in academia through large scale donations. I don't know if that was the reason that Flordia went with Windows, but I have seen it elsewhere. When I ran a school engineering project, we received a computer from Intel. I then received a letter in the mail from Microsoft requesting that a sponsorship sticker be placed on our vehicle. Seeing as how the first thing I did was wipe Windows off that donated machine, I declined.

Well of course they ran Xp (1)

Only underwater and in space, is the vacuum of suck, produced by Windows, useable to it's full potential.

I'm one of the competitors (Amador H.S) (1)

Hex4def6 (538820) | about 9 years ago | (#13287931)

I was part of the Amador team, the only H.S at the competition. We placed 5th, which isn't too shabby :).

This year, I think that teams had a lot more bad luck than previous years -- one teams, the univ. of victoria, had their lead programmer / team leader leave 2 days before the competition, after deciding that sub's just "weren't his thing." Since they used custom PIC circuitery etc, they were basically screwed.

We a catastrophe happen to us as well -- our PC104 computer fried hours before the qualifying run. We then started looking at using a basic stamp as our main computer -- amazingly powerful little things, they allow something like 16 serial IO ports.

joelsanda (619660) | about 9 years ago | (#13288222)

This year teams were challenged to complete three tasks including finding a docking station, inspecting a pipeline, and surfacing in a recovery zone marked by an acoustic pinger.

Yeah, I'm all for the machine age but my kid, who is seven can do this after his usual breakfast of two Eggo waffles, a glass of orange juice, and a bowl of sugar, er cereal:

  1. Navigate staircase
  2. Inspect room
  3. Clean room
  4. Return to Dad's acoustic shout down the stairs

All without Windows. And he's basically open source, too boot!

Where can we download his genetic code? Or is it not under the GPL?

I don't think describing the download of genetic code is typical /. material ... Besides, I'm sure the process has been patented, which would mean my describing online violates the DMCA and the patented process of downloading genetic code!

Re:My kid does this powered by Eggo waffles (1)

Binestar (28861) | about 9 years ago | (#13288693)

I know in general how to download genetic code, but that's not what I'm looking for here. I want a copy of your son's genetic code. Perhaps the method of creating a son is self evidant, but I've tried MULTIPLE times and only received daughters. Was wondering if I could look at a diff.

As I heard it from one of the competitors, the water was all murky and none of the teams' algorithms worked.

Time to preorder water samples for next year.

Go Felix!

Amador High School (1)

cmplus (681254) | about 9 years ago | (#13288674)

Kudos from this high school CS instructor to Amador on their 5th place finish. They should be commended for their effort. It not easy pulling together all the resources and getting kids to stay on task all year. Well done.

Personally, I'd like to see more of this kind of thing offered as an alternative to the AP curriculum. Sorry, java simulations of fish in a lake doesn't cut it with generation-E. This stuff however, fires imaginations.

"Sup yo, we got like 5th or something."
"We're like smart 'n shizzle yo'."
"How you gettin' home?"
"Madre yo'. We'll load this b-itchell in the back of the Tahoe. Don't smell no mo' yo'."
"Koo."

jeepliberty (624159) | about 9 years ago | (#13288816)

Good job swimming with the big fish. Your website was very informative too.

You should post some actions shots of the team and the murky environment. Update your resumes too.

It's always refreshing to see young kids compete and do well against well-funded colleges.

Heathkit (470499) | about 9 years ago | (#13288804)

I really enjoyed the spirit of communication among all the competitors in the past two years I've done this.

I was wondering if we should set up some kind of community (mailing list, forum, whatever) to share ideas.

My team (UTD) had leakage problems too, and I think that's the kind of thing we can avoid if we all have a way to get together and share input.
