Slideshow: Nautical Robots Ride Out the Storm
1/2/2014

Image 1 of 10      Next >

The Coralbot project underway at Heriot-Watt University in Scotland aims at designing an underwater robot that can rebuild the world's damaged coral reefs. Left on their own, coral reef regrowth and regeneration is a very slow process, partly because many pieces get scattered far apart. A swarm of Coralbots will find and collect pieces of living coral and bring them back together to speed regrowth efforts. This help is especially needed right after hurricanes or destructive fishing practices like bottom-trawling. Humans have done this in the past, but this takes time and there's a lot of acreage to cover. Marine biologists, computer scientists, and robotics engineers at the University's Ocean Systems Laboratory are now working on the Nessie 4 autonomous underwater vehicle (AUV), their latest prototype, which has passed some field tests in open water.

Re: Backyard pool

The in-pool cleaner I have is the Hayward Navigator; Using no power cord, its cleverly designed to use the suction power of the attached vacuum hose to mechanically convert the suction action into a walking action, using two offset cams like a bicycle pedal.  The device walks around the pool constantly, as long as the pool pump and filter are on for the day.

Looks un-seaworthy

The Coral Bot Nessie 4 shown in the first slide, just doesn't look like it would maintain a level buoyancy; It looks front-heavy, and apt to roll ,,, like the pitch and yaw would be very difficult to maintain. Was that model actually reduced to practice-? (image looks like a rendering)

If anyone would object, the likely environmental group would be the Sea Turtle supporters – Jellyfish is a favorite dietary staple of Sea Turtles. Where I live near Ft. Lauderdale, its common knowledge that ZipLoc bags littered into the water, are mistaken as Jellyfish by Sea Turtles and they wind up asphyxiating themselves. Accordingly, people –even non-environmental fanatics – are very sensitive to littering Ziplocs in particular!

When you have to explain your joke, it kills the humor. 

And yes, ZigBee is short range, like Bluetooth; but very narrow bandwidth (small data), and very low power, so it can optimize battery life. This is a cool application for ZigBee; that is, if you support messing around with Mother Nature! (not that I like Jellyfish, but this seems like jelly-genocide.)

Glad you enjoyed the slideshow, Ralphy Boy, and thanks for the interesting stuff about TALON.

A while back we made some battery packs for TALON base units. That base can have a wide variety of attachments applied to it to make whatever... Since we didn't pressure test those packs for underwater use I'm guessing they are not on the beach comber shown in slide #9. I'll watch for hints of this use in any future builds of TALON packs now that I know about these.

And thanks for the photo Ann. We have a few TALON versions on the walls in the assembly area, and now we'll have the Beach Bum Harassment model too!

The jelly fish killers are interesting. I was in NE Australia in Nov 2012. It was eerie to be on a beautiful beach at mid-day and have no one in the water. Coming from Jersey where some of our beaches get pretty crowded I found myself feeling sad at the waste of miles of beach.

They have the deadly Box Jelly Fish to contend with. I read that they test the surf regularly to decide if the beach can be opened. A school of these could give real time data on stinger presence or absence, and grind up the little nasties at the same time.

But then again... some of the beaches were also closed because of CROCKS... Whole 'nother robot needed I suspect.  

BTW... After printing that TALON picture I noticed it has what looks pretty much like a fishing rod pointing out the back. Pfft... But no beer.

far911, yes that's the correct definition of ZigBee. In case it wasn't clear, Chuck and I were joking about the jellyfish's ability to understand ZigBee.

@far911: So what happens if they signals breakdown ? Also what sort of a distance does the signals communicate through ?

ZigBee is a specification for a suite of high level communication protocols used to create personal area networks built from small, low-power digital radios.  Is it?

Seems like pretty soon we will be sitting idle and everything will be done by robots for us.

Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
