Give me full details !!!
Do U know how to snorkel ? Are U trained as a technical in a collage ?
What have U built so far in your life ?
I have thought about it and even if English isn't your first language most languages have some polite request in them.So the answer is NO look for your self.
Have you tried using the search at the top right? The first two hits for "under water rov" seem to have all the details you could need.You can also check the Related column on the right for those and other related projectsIf those are not to your liking try a google search for "make an under water rov" to find even more projects.Good luck!
+1(And a "please" would have been nice as well)
