Unmanned Submarine

Former Member

I'm new to the single board processor hobby but I am working on an idea of an unmanned exploratory submarine.  Requirements would be GPS, Camera with small LED light for underwater pics, capability of location transmitting and solar cell for self recharging.  Would like to be able to launch to a coordinate and have it return days later, taking  pics along the way and self surfacing to recharge as well.  Any ideas or suggestions?

  • Here is a link to a book about the technology on AUVs that might be of interest.  http://www.amazon.com/dp/0415301548/ref=asc_df_04153015483180506?smid=ATVPDKIKX0DER&tag=pg-1583-86-20&linkCode=df0&creative=395097&creativeASIN=0415301548    . The specification of 1 meter in length coupled with the need to keep the shape hydrodynamic will limit your space for batteries. You might get an hour between needing charges. You will also have to have a high pressure air supply on board to control depth with ballast. This will be a consumable resource and will limit the number of times you can go up and down unless you have room for a high pressure compressor and related support mechanisms. Your other option is to have the sub slightly positively buoyant so that it will naturally float to the surface. The disadvantage to this is that it will have to use its planes to pull itself underwater and this will increase the resistance in the water and shorten the distance between recharges. When one starts to think about all the complications it makes you really appreciate the advantage of a biological organism like a fish that can swim and dive for years, pull its fuel from the environment, and probably know exactly where it is all the while.
