After a long week of Finals and an all to short Spring break, we are back and racing to finish our final prototypes for the June deadline! We’ve made significant progress on our communications array with the ability to control the raspberry pis from a few hundred feet. The hull has undergone some rigorous pressure tests to find leakage and slippage within its O-rings with a final to be completed sometime this Saturday. Here are some photos from our recent tour of the SIO pier, and our first day working in the MESOM laboratory.
These last few weeks have been a whirlwind of progress and research! Software Updates: We can send serial data over web-sockets and control arduino boards through Ethernet. Transitioning to a wireless link soon. Data transfer is nearly instantaneous but we still need to see wireless functionality. Mechanical Updates: Finishing up Pressure Hull for testing on Saturday. Once that passes the test, other teams should be able to use the hull. Decided G-Flex resin works well. XTC resin results are inconclusive. Using G-flex for our current Pressure Hull. Printed a part of the hull to mount the thrusters and cable penetrators. Modifying designs to make screwing in thrusters easier. Electrical Updates: Created voltage step down design for all four batteries. Need further tests to determine voltage draw from sensors. Simulated wiring for the rasp pi’s (using one battery). Decided on voltage regulator for circuits. Oceanographic Updates: Researched and decided upon Brine tests methods, should be implementation on Saturday. ArcGIS maps developed […]
What problems came up in designing the first PLA hulls? Making them watertight. While conventional 3D printing is fantastic at making strong and unique structures above water, once submerged, PLA becomes waterlogged and leaky. We tested several methods of printing and treating PLA and discovered that, despite the highest print settings we could manage, water can always slip in between the microscopic hulls within the prints. Our solution is to treat the hulls with 2 part resin after they print. While our first tests were messy and poorly cast, they proved extremely watertight! Our first tests included placing paper towels within the hulls to find any leaks when submerged. After 3 days of being submersed the pieces were sawed in half and the paper was dry as a bone! We then began printing larger versions with press to fit joints. To assist in our full size conceptualizations we printed “Humungo,” the first full size print of a hull. This next […]
Between all the exams and lab time, we love to find time to meet industry leaders in BlueTech. Today we visited Teledyne Seabotix at their campus in MiraMesa and were able to see industry grade ROVs and AUVs. It was incredible to see where our projects today may lead us!
If we wanted to hear the “heartbeat” of the ocean, how would we listen in? Today we took a step closer with our first Hydrophone sensor test within the lab. By routing this underwater microphone into our Arduino Mega we were able to read live data from our snapping fingers. Here you can see each finger snap as it was conducted within the first moments of the data stream.
Today was the best Monday we have had in many weeks. We are proud to announce that we were awarded $11,701 by the Marine Sciences Academic Senate Research Committee at SIO. Our proposal to design and deploy low-cost, ‘expendable’ AUVs is making waves with its scientific potential. The ability to send AUVs into hostile environments at little cost will open up the gateways of future research, and now with a little funding we’ll be making headway like never before! Here’s to many more serious meetings like the one below, we’re glad to have you along for the ride!
Hello and welcome aboard the team! It is an honor to have you beside us in the coming months. We’re excited to keep you updated on everything we do as we prototype and build Terminus, the first to come in a long line of innovative underwater robotic platforms. Now if the idea of young engineers building exploratory underwater robots excites you, makes you curious, or gives you hope for humanity, you’re going to love who we are. Yonder Deep (or just Deep) is a fully undergraduate run organization at UCSD founded with one vision, To empower students to make tangible differences in research, by inspiring life-long experience through underwater robotics. Within our first weeks of coming together as a group, we made headway into the world of oceanography and research. The prospects of helping climate researchers globally excited us more than any free food the university could provide.
