[Bre] dug up this excellent robot fish prototype project. The PPF-O9 has three servos. One on the forward fins to control depth, one on the middle joint, and one final one drives the tail fin. The battery box is mounted to the underside. The control scheme is interesting: the right stick controls left/right and up/down while the left stick controls the frequency and amplitude of the motion. They say the robot is fairly stable, but swimming and turning can be slow. They’ve included CAD files for almost every component to help you with your own designs.
In June, we highlighted a robofish designed for swarm communication.

AutoCAD is so expensive, $4500. We offer progeCAD IntelliCAD at 1/10th the price. progeCAD natively reads and writes DWG files, no conversion. Supports AutoLISP, .mnu files, has solid modeling, photo-realistic rendering and much more. Download a free 30 day full trial at http://www.icadsales.com and save thousands for essentially the same software.
very smart, I like this robot fish from Japan which swims like a real fish
Can it swim in the water for a long?
