We recently mentioned a homemade $99 ROV that some people complained wasn't really a ROV. Well, here's another DIY ROV that uses $20 bilge pumps as thrusters; and eBay’ed vintage Atari joysticks as controllers (the use of which the designer discusses at length). Doug Jackson named his contraption BOB. Total cost was around $500; the underwater camera system accounted for half that.
BOB is 19 inches long, 13 inches wide and 9 inches tall (including the floats on top).
