First pool test of the year
September 24, 2009
Team SONIA is proud to announce that we already have a pool test under our belt this year. We had a pool for 4 hours this saturday, giving us plenty of time to reproduce last year's competition obstacle course.
Even though many members of our team graduated last summer, we were able to complete a great portion of the course. In 4 hours we manage to do the following task:
- Gate
- Pipe
- Bouy
- Pipe
- Head for pinger
- See the briefcase
- Surface
At the end we were also able to grab the briefcase by only testing this part of the mission. We did not have enough time to chain the grabbing part to the rest of the mission.
You can see the pictures of this test right here!
The team was very satisfied of this first test and we are looking forward to the next test in the upcoming weeks.
Final day!
August 2, 2009
Today were the final runs of the AUVs. After the qualification, we ranked in 9th position out of the 10 teams that made it in the final. Our team was able to do one test in the morning to validate that our software was working properly. Our final round was at noon. Unfortunately, it seems Murphy was still close. We were not able to do more than pass the gate. After some analysis of the logs, we found that the problem was a bad setting in our vision software. The settings to detect pipes were not entered properly, thus eliminating our pipe detection capabilities. After 2 minutes of search patterns looking for pipes, our mission timed out and we headed for the pinger since it is worth a lot of points. Because of a problem with the elevation of our passive sonar board, the vehicle was not able to tell when it was above the pinger. To fix this problem we made our vehicle look for the briefcase while navigating toward the pinger to know when we are over the briefcase. During the final run, while heading for the pinger, we passed over the bins. Our vehicle mistook them for the briefcase only for some frames, creating a false positive. Sadly it was enough to enter to grab state but our vehicle could not find the briefcase anymore since it was not there for real. Our vehicle then surfaced in the middle of Transdec. This run gave us the last rank in the final, giving us the 10th position out of 30 teams this year.
We would like to thank all our sponsors who helped us this year. Without each and every one of them we would not have been able to participate to that competition and build this vehicle. Their help was much appreciated and we hope to do business with each of them again next year.
We would also like to thank all the members who worked on the project this year. Without their help, our prototype would not be what it is today.
We would like to congratulate the teams from the University of Victoria and Rhode Island who respectively ranked 2nd and 3rd this year.
Finally, we would like to congratulate the team from Cornell University, CUAUV. They were able to complete the whole obstacle course in less than 12 minutes. They made an extraordinary job that no one has been able to do this year. With that awesome run they ranked 1st.
We will be back to the competition next year for sure so keep watching our website for updates trough out the year as we will do our best to keep you informed of our latest developments.
Good luck to every team and see you all next year!
2nd Qualification day
August 1, 2009
We had our 2nd qualifying round today. Unfortunately we had problem during the 15 minutes of the qualification. We did not manage to do more then pass the gate. At first we did not know what the problem was. We even did a test 20 minutes after our qualification round and everything was fine. Later the same day, we inspected the logs of the qualification round and found out that our vision server had a communication problem with AUV5, our decision software. Right now we hope that we will make it in the final tomorrow.
1st Qualification day
July 31, 2009
The day started really early once again. We had a practice run at 7h00 am to make sure our vision settings were correct. We then had our qualification run at 8h30. We manage to do the following tasks. Gate, pipe, buoy and pipe. We were also able to navigate toward the barbwire and the bombing zone but we ran out of time to complete those tasks. Overall we manage to finish 3rd today after all 23 teams did their qualification run.
We also received the static judging result at the end of the day. ETS finished 2nd place out of the 30 teams. Congratulation to Cornell who finished 1st for a second year in a row.
Tomorrow we will be performing our 2nd qualification run at 15h00. Don’t forget to watch our twitter page for quick update throughout the day.

About SONIA
The SONIA AUV project from the École de technologie supérieure, entirely composed of volunteer, undergraduate engineering students, is devoted to the development of an Autonomous Underwater Vehicle (AUV).
Since our beginning in 1999, we have developed 7 AUV prototypes with the goal of competing at the AUVSI and ONR's International Autonomous Underwater Vehicle Competition. Recent years have seen us consistently ranking in the top 3 positions with our award winning designs
Since our inception, we have collaborated extensively with local and national industrial groups to develop new prototypes, promoting the use of our partners' technologies. This commitment to develop strong long-lasting partnerships with the industry will help our team to outperform our expectations for the 2009 competition. We would like to thank all of our partners who have provided us with 100% of our budget.
