On Sunday, April 17, 2011, CUAUV held its first control test with Drekar, the new vehicle, at Teagle Pool. Drekar functioned very well, resulting in a quick and smooth test. Vehicle control worked surprisingly well with zero tweaking, and it seems that Drekar is already faster than Tachyon. More testing will be performed next week.

On Friday, April 15th, CUAUV led lab demonstrations with Cornell prospective students. The purpose of the Cornell Admissions Lab Demonstration is to get students excited about Cornell Engineering and encourage them to join engineering project teams in the fall. Hopefully, we see some of the students we met during the fall recruitment next year! Go Big Red!

On Saturday, April 9th, 2011, CUAUV hosted an outreach event at the Ithaca Sciencenter. During our presentation, we led cool demos with the kids, like torpedo launching and image recognition. We were excited to bring hands-on science activities to Ithaca’s youth and look forward to doing more presentations in the near future at the Sciencenter!

CUAUV is proud to announce that this year's competition vehicle will be named Drekar! The name is a collective term for Viking ships, which were slender and flexible boats with symmetrical ends. The team is certain that the new vehicle will live up to its extravagant name.

The Power sub-team has recently finalized the battery pod board. The board has the same core functions as it did last year; however, there is a new battery management chip specifically designed to handle the necessary tasks. In addition, instead of using small fuel gauge IC components, there will be a fully integrated DCDC and a more efficient cell voltage measurement that uses a sample-and-hold measurement style instead of the old voltage divider. The new battery management also has freed up I/O pins, which will allow for future expansion. Moreover, if all goes well, charging the vehicle’s battery will not require a charging station but will be as easy as charging a laptop. Stay tuned to our weekly status updates regarding the recent finish of our design process...

On March 12th, 2011, the Cornell University Autonomous Underwater Vehicle (CUAUV) project team hosted a workshop for Girl Scouts intending to earn their Science in Action badges. CUAUV has held this workshop for the past four years, and the attendance has always been large. This year, fifty Girl Scouts were present at the event, and all of them were entertained by the activities prepared by the team. All of the girls cycled through five stations, and at each station, they learned principles of science through hands on demonstrations, such as how sound travels by making a telephone out of two cups and a string and how bridges support heavy loads by making a bridge out of newspaper.

The sensor team has made some improvements from last year’s model. This year, the team is using three boards and a custom-built IMU instead of last year’s 3DM-GX1. The IMU, or Inertial Measurement Unit, integrates two COTS sensors, reports linear acceleration and angular velocity, and is easier to customize. It is also less than half the price as last year’s 3DM-GX1. Stay tuned to our weekly status updates regarding the recent finish of our design process...

The Structure sub-team has finalized the overall structure of the 2010-2011 competition vehicle this past week. Besides being more compact due to the shorter hull, there will be no external skeleton structure. The sub-team has also improved the vehicle’s structural strength by replacing the previous plastic tubing with aluminum tubing. Stay tuned to our weekly status updates regarding the recent finish of our design process...

The first team social of 2011 was… competitive. From intense X-box games to Quelf to Settlers of Catan, the members of the CUAUV team brought their game faces last night. Despite the very strange noises that arose from those engaged in Quelf, the team had a great time playing games, relaxing, and eating cake. Maybe the Quelf players laughed and asymptote’ed each other carelessly, but those playing Settlers were concentrated in their quest to conquer Catan! Everyone had a great time, and we look forward to our next team social in March!

The Racks and Caps sub-team has recently finished the design for the Upper Hull Pressure Vessel (UHPV). Since the purpose of the UHPV is to keep the surrounding water out of the machine, the Racks and Caps team has made sure the material used is not only waterproof but bulletproof as well. The electronic rack, which holds up the electronic boards, is almost finished. The Racks and Caps team has also installed larger fans to cool the running computer. However, for CUAUV, bigger does not always mean better, because this year’s UHPV model is about half the size of last year’s. And finally, the Racks and Caps team just installed a total of 5 layers to hold the being-built electronic boards. Stay tuned to our weekly status updates regarding the recent finish of our design process...
