@JimT-Unexploded ordnance is a majour problem around world. We all know about the damage land mines pose to locals in former war-torn areas. Sea mines are just as dangerous and distructive.
I think that is good idea william, although i have never watched the deadliest catch i know how dangerous it is. I would help you but i am not an engineer and also i dont know much about how to make projects that require sensers, robots ect.
I think you're onto to something, Bill. Every time I watch Deadliest Catch I wonder if technology could make that job safer. Now, we need a robotic alligator finder to help those guys on Gator Boys.
I was just thinking about these types of applications this week. It's not as elegant and sexy as underwater mine detection, but how soon before someone designs an autonomous crab trap?
After several seasons of Deadliest Catch, each time I see it on TV I think of the opportunity to design either a self-navigating underwater crab trap, or a self-navigating underwater crab trap deployment/collector. Now that the fishermen of Deadliest Catch can live off of their residuals from the Discovery Channel, I would assume that we have all of the technology required to design a system that:
1) Propels itself along the sea floor
2) Uses sensors to detect high populations of crab
3) Deploys a baited crab trap or simply parks its integrated trap on the sea floor
4) Detects when a predetermined number of crab have entered the trap
5) Collects the filled trap or launches off of the sea floor
6) Navigates back to port autonomously
Not only would it be lucrative, it would also reduce the fatalities in the #1 deadliest job in the US, commercial fishing.
I'll get the drawn butter ready if anyone would like to join me on this project.
I get that this new algorithm takes a pass-by-pass approach (like cutting the lawn) over the old methods of big-image & zoom-in. But I'm not sure I understand the Navy's interest in locating explosive devices on ships which have already sunk. These impose Risk to someone-? And they've been 10 years in development on this-? I think I'm missing the value-added point of this project ,,,,,(?)
@Ann- From what I'm reading, the function is the same but the operation is different. The HAUV requires human interaction and the HULS moves underwater and around ships on its own.
I know the Navy struggles with keeping EOD (Explosive Ordnance Disposal) units fully staffed with highly qualified candidates. Mechanizing underwater mine sweeping would require less manpower. And, the Navy could focus more training on the skilled EOD techs for other operations.
What the Navy calls HULS resemble some of the existing autonomous underwater vehicles (AUVs) and remotely operated vehicles (ROVs) we included in the nautical robots slideshow, especially the Bluefin Robotics hovering autonomous underwater vehicle (HAUV): http://www.designnews.com/author.asp?section_id=1386&doc_id=246206&image_number=13 Since this basic technology has been used by the military for some time, including for mine detection, I wonder why the Navy has decided to invent its own versions?
Actually,this is a lot like those robots you can buy that autonomously sweep your floor. They are just much more sophisticated. Of course, they might want to look at other sensors, like vision. Since the robot can, on the second pass, get close to the hull, that could work.
This seems like a perfect use case for a robot partner when you consider the danger factor related to the underwater mines coupled with the difficulties humans could have navigating under water. Sounds like a lot of complex thinking went into the design, especially around the computer graphics algorithms and use of sensors.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
