All Wave Glider autonomous unmanned marine vehicles (UMVs), including the new SV3 shown here, consist of a surfboard-sized float tethered to an underwater propulsion system that harvests energy from waves as the primary propulsion source. (Source: Liquid Robotics)
Rob and Chuck, this robot has successfully completed several different multi-thousand-mile voyages across the Pacific, and is used by the US government and private firms for long-term, unattended missions that last up to a year. It's built to handle just about anything, including collecting data during Hurricane Isaac: http://www.designnews.com/author.asp?section_id=1386&doc_id=250192
When I first heard of the Wave Glider, its propulsion system was what intrigued me the most. Thanks for posting that link, RHar. the company has put a bit more info online about how this works than when I first wrote about it last year. In any case, it struck me as one of those "why didn't someone else already think of it?" obvious-in-hindsight inventions.
Very informative. I had no idea this technology existed. I did look on their web site but did not see any information as to how the robot was guided. Do you know what steering mechanism is used to get from point"A" to point "B"? Excellent Post Ann.
Yes Anandy You are correct these robots can be used by navy in their missions, Secondly they can be very important asset in getting soil ,underwater and earths crust information. With all these information one can take precautionary measures if god forbidds some natural disaster comes into notice
Clinton, thanks for the kind words. Putting these robot slideshows together is a lot of fun (as well as a lot of work). I also try to give some context to our readers, since, as a reader myself, I have the same frustrations when that's missing. Glad to hear this effort is useful.
Debera, we've done a couple of slideshows that include unmanned underwater vehicles (UUVs), autonomous underwater vehicles (AUVs), and remotely operated vehicles (ROVs). Here are the links if you're interested in finding out more: http://www.designnews.com/author.asp?section_id=1386&doc_id=262528 http://www.designnews.com/author.asp?section_id=1386&doc_id=246206
Nice follow up story. It is interesting to see how they are evolving their design and use of solar energy.
One of the things I really like about your columns is that when relevant or useful, you reference past articles, bringing expanded insight to the current article or updating the information that the old one provided with new developments. And you provide links to make reading further easy.
When reading columns in Design News or on other sites, I often find that I remember previously reading a related article that has relevance to the current one, but don't have the time (or the organization) to go and find it on my own. You usually do that for us, and it is appreciated.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
