Ocean Research Robots Video and Drogue Sensors

I found this video from UC San Diego and the Scripps Institute of Oceanography. Prof. Jules Jaffe talks about buoys, sensors, and swarms of cheap data sensors. While watching the video I  learned about the concept of a drogue buoys that change their density in order to change the depth at which they are collecting data.


After some googling, I found the UCD mechanical engineering student research project website with more information on teh specific build. From this, I’ve decided to use a water tight cylinder for the electronics enclosure and have been reading up on o-ring designs and thinking more and more about the enclosure.

C. 2012 SPAWAR Ocean Monitoring Vessels (website)

D. Research Article: submersible drogue

Based on the images and the video, here are some ideas that I have been working on. Special thanks to Dan Spangler for the idea of incorporating a twist-lock mechanism and electronics frame into the water tight cylinder assembly for easier repair and maintenance of electronics.
