My Masters Thesis is Finally Done

My MSEE thesis is now complete and I’ve satisfied all of my requirements for graduation from the electrical engineering department. My thesis is entitled “Design of a Reliable Embedded Radio Transceiver Module with Applications to Autonomous Underwater Vehicle Systems“. Well, I guess this concludes my edumahkayshun, and now I gots ta git me a reel job.

University of Washington Robofish on You Tube

My lab’s robotic fish are now on You Tube:

This video demonstrates robot fish schooling

Underwater camera view of our fish

The comments on YouTube about this video resmble the same questions and comments we received at our open house demo – especially the one about laser beams. LOL. Two comments were notable though:

Robot Fish for president! They have more brains than the current candidates!

Well, at least in the case of His Holiness the Liberal Savior (Barack Obama), I agree. A PowerPC processor clocked at 40 MHz would do a much better job of running our country.

thats really kewl. the people who made those r geniuses ^^

Yep, I agree with that one too! :D

Lots of Media Interest

I found out what happened. Our research was originally detailed in an article at UWeek (the University of Washington’s News Site). This article was started all of the media activity and was quoted at Ocean Lines, EurekAlert!, and Slashdot.

This was followed by a news cast at King 5 (Local News for Seattle).

Our work was also featured at ZDNet and Science Daily. Very cool. Today I learned that the Mumbai Mirror also wrote an article. In the Mumbai article, we’re referred to as “boffins” – apparently British slang for “scientists”.

All of this activity isn’t surprising – robots are cool. Robotic fish are even cooler. We’ll be doing some more demos for reporters wanting to show video of coordinated maneuvering of the robotic fish. When this is posted, I’ll let you know

Robot Fish on King 5 News

My lab’s work was featured on our local Seattle News station. I designed the radio transceivers that the robotic fish use (you can see a green wire antenna sticking out of them while they swim). Ben designed the actual fish and its unique swimming mechanism (fin actuation). He’s got a sweet CAD model that I’m using in my thesis. Dan built the camera tracking system featured in the broadcast. We used that tracking system to enable autonomous swimming for our open house demonstration that I described a few posts ago.

Internet Black Holes (the invisible /dev/null beast)

The University of Washington has some great ongoing research projects. This one made national news at MSNBC (article: here). The Internet’s backbone consists of many thousands of routers speaking the TCP/IP protocol. TCP/IP was designed at DARPA (the Defense Advanced Research Projects Agency) to allow network traffic to take multiple routes to a destination. This provides for communication if one or more of the routers fails – a likely scenario in the event of a nuclear war. Because destinations can be reached though multiple routes, each individual path may or may not link to its destination. If it doesn’t link, any traffic that uses that route gets lost, forever. Never before have these ‘bad routes’ been charted. The CS department developed a tool to search for and track these black holes and they affectionately called it UW Hubble.

UW Engineering Open House – Little Red Hen’s Take

My husband's labTime for my take on my husband’s robotic fish and Engineering Open House. I had a really good time today! If Friday was the day for field trips, then Saturday was the day for families. I came to the open house today, Saturday, and got a kick out of observing the family dynamics of those who came. Some parents seemed to have engineering in their genes and wanted to share their interests with their children. Others were clearly bewildered by the technical questions their children were asking volunteers but were being good sports trying to feed the minds of their little Einsteins. I enjoyed watching Patrick field questions from adults and children alike, and my favorite interaction was between a father and Patrick. It went something like this:

Dad: So do you like video games? [Read more…]

Robotic Fish at the UW Engineering Open House

Close up swimming fishMy lab hosted another successful engineering open house exhibit today at the University of Washington. I’ve been working in the Nonlinear Dynamics and Control Lab at UW for two years now and I’m close to completing my masters degree. My thesis is based on a radio transceiver that I specifically designed to enable underwater communication between our three robotic fish. Today, my transceiver was used to demo our work to the UW community and visitors to the university. [Read more…]

My First Paper

Finally some published research. Yah!

Autonomous Underwater Multivehicle Control with Limited Communication

Lonely Weekend

My beautiful wife is scrap booking with her sister this weekend in Oregon. So I’m here all alone :( So what do I do?…. Order Quiznos and watch zombie flicks! I highly recommend 28 Weeks Later.

Well… that’s just today (Friday). Tomorrow I’ll be knee deep in firmware as I try to design a working RF protocol for our transceiver board.

LOL. Take care everyone.
