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.

I would think that really powerful waves could provide more energy than this robot can handle, Rob.

bobjengr, there's a brief discussion about propulsion on their website, which RHar helpfully posted below. Here's the link again: http://www.liquidr.com/technology/wave-motion.html

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.

Good point, Chuck. I alslo wonder if the device is built to withstand rough seas. That might provide a bit too much energy.

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

Ann,

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.

Thanks for your efforts.

Clinton
