5ft Depth Test

6.29.2010 Pool Tests

Today was the first day the entire team took the AUV down to conduct some tests in the pool. We took the AUV to the diving well in Lejeune Hall to tweak the gains on the controllers. You can see from the graph that the initial gains caused the vehicle to be unstable, but for the second test we changed the gains and it worked well even with a disturbance. We also worked on the heading and pitch controllers.  Although they aren't quite where we want them for competition, we have been able to make significant improvements.  Today was very productive but we won't work much for the next two days because we have been loaned out to help with I-Day here at the Academy.  Come friday and next week we will be in full swing.

USNA AUV Team 2010

USNA is getting ready for the 2010 AUVSI.  We've got only 4 team members this year and our project adviser is still CAPT Jack. Team Captain is 2ndLT Joseph Jennett, with 2ndLT Kevin Fleischer working with the cameras.  ENS Harry Davis and MIDN 1/C Paul Schouppner are working on the programs.  So far this year we have changed out the DVL, redesigned the power supply, rewritten the code, and created some new circuit boards that replace two old circuit boards.  We also had to fix the tail of the frame that held the aft thruster on after it broke earlier this year.
Starting next week, for the first time this summer, the entire team will be here working on the vehicle at the same time.  We've all got different schedules and other things we have to do, but for the next couple of week everything will be about winning the 2010 AUVSI....
