This Rov was pretty much just something to fool around with and not necessarily meant to be taking as a full blown Rov.
This project has been on the back burner for a number of years and I just recently started working on it again. I'm still not sure if it is actually going to work or not but if it does it will have 3 degrees of freedom, a working camera w/mic, led lighting, and it's working depth will probably only be about 5 to 10'.
The image to the right was about as far as I got before the project was shelfed. I will be adding a few new pictures as I continue the build but I will not be going into to much detail of how its made because I don't think it would be worth repeating.
If your looking for something small like this to toy around with I would sudgest the Mini ROV kit by MadLab.
