Success
I am pleased to report that the SMU Robotics club, after so many setbacks, has managed to place 9th overall in the AUVSI competition. This is absolutely outstanding, and far greater than we had even hoped to achieve. We won two awards last night at the final awards ceremony. The first $500 award was for our successful (albeit last-minute) completion of the optional JAUS challenge. The second $500 award was for "perseverance in the face of adversity," an award we are very proud of. The results of the contest, as of the time of this posting, are not yet up on the website, but will soon be linked from this page as soon as they are up. On behalf of the entire club, I would like to thank all of our supporters. After a hectic week, we are all but too happy to finally be taking a break. We will resume work this fall for next years competition, so stick around for more news from the club this fall. Until then, go Mustangs!

Qualified!!
Since we were so desperately in need of a "reed switch"--the exterior kill switch required by the competition--the team spent a good part of last night on a mad hatter shopping trip, driving from store to store in search of the appropriate equipment. This was all made even more fun by stuffing all five of us into Andrew's little station wagon. (Have you met Nathan Huntoon? 6'7'') Apparently not all Wal-Marts are open 24 hours a day, and not all gas stations take credit cards, so our relatively simple mission sent us traveling through three cities and forced us to backtrack more than once. The guys were up until 2 am working hard on the submarine.
But, hard work has a tendency to yield positive results, and the team was soon to be rewarded. The reed switch bought at Wal-Mart was a failure--too weak for our purposes--but our friends at the Naval Academy came to the rescue with a spare switch of their own. Both officers and gentlemen, they are.
When it came time to do the all-important qualifying run, everything was prepared, and Seahorse 2 passed with flying colors. The diver who monitored the robot's journey through the gate said, "Well that was anti-climatic." No problems, no tricks: just smooth sailing. See for yourself and watch Austin's video of the event.
The rest of the day was a bit more laid back as the guys concentrated on the next obstacle: light detection. For those of you in the know, there was a problem with the FFT (Fast Fourier Transform) method, but this was solved by switching to the simpler DFT (Discrete Fourier Transform). Once the code was fixed, the guys moved onto building, but not without a few pitfalls. Handy guys that they are, Nathan accidentally sautered his pants leg (that is, dropped melted metal on it) and Austin splattered his hand with epoxy. No pain, no gain, boys.
Tomorrow we'll try to qualify for the finals; our runs are scheduled for 9:20 am and 5:00 pm.

Breaking News: English Major Drafted Into SMU Robotics Club
So about the last place I expected to be right now was sitting at SMU's booth at a robotic submarine competition with a "Competitor" lanyard round my neck. But the Robotics Club summoned me to do my Mustang duty and I gleefully answered the call. We've decided that if anyone asks, I'm supposed to say I designed the light detection circuit (whatever that is). Club member Chris Pilcher was the actual designer, but he sadly could not attend. (Thanks for the cover, Chris!) As a technologically-illiterate English major, I feel like a spy in foreign territory.
Unlike soggy Dallas, the competition site in San Diego is temperate, sandy, and boasts a glorious ocean view. People--mostly young men--mill around comparing submarines and having technical conversations that might as well be in a foreign language for all I can understand them. The booth next to ours houses the United States Naval Academy. With their crew cuts and big, fancy robot, they're a little intimidating but very nice. On our other side is the team from San Diego, who have been really friendly and let the guys use their drill press. In fact, most everybody at the competition seems genuinely cooperative: teams borrow and lend each other tools and materials of all kinds. A couple of staff members just dropped by and listened to our wonderful story of theft and recovery; they offered to help us with anything we might need. Overall, it's a great environment to be working in.
A new development: the guys have just solved a last minute problem with some good old-fashioned Texas ingenuity. The little propellers on the robot are required to have "shrouds," which are covers that protect the divers in the water from getting their fingers chopped off by spinning propellers. What with the theft and all the hoopla surrounding it, those covers never got produced. In the last hour, these guys cut circles out of a kitchen cutting board and added the bottoms of plastic water bottles. Voila: instant propeller shrouds. The San Diego team looked on with grins. "Way to stick it to the man," one said, applauding the guys' decidely untraditional materials.
On a different note, what's the real purpose of an English major on a robotics team? Well, mostly, it was the easiest way to get me on the naval base. My fiancee, Andrew, and I are making San Diego the first stop on a month-long road trip, and I didn't much want to stay at the hotel for four days. But more importantly, I have an essential skill: the ability to write interestingly. I have thus designated myself Official Team Blogger. Austin didn't seem too upset to relinquish his blogging duties; I think he'd rather be writing code.
Apparently, the vastly important reed switch--which does something or other--has mysteriously gone missing. The drama never ends. Check back in tomorrow for the first day of actual judging.
