I'm interested in hearing about variations of the OpenROV design that people have built. Someone posted a picture of their quadracopter-inspired design, which was cool but I'm interested in hearing about other variations too.
I'm working on a ROV design using most of the same components (camera, electronics, motors), but uses a cylindrical, in-line design rather than the rectangular framework that OpenROV and many others use. i.e. the direction of travel will be along the axis of the pressure hull, not perpendicular to it. with the exception of the thrusters protrusions, the ROV will be 4 inches in diameter.
I'm going to try to keep it simple for now, but in the long run, I have a few interesting things I want to try:
- Sealed, pressure compensated thrusters - The idea of salt water in my motors just bugs me.
- Wireless communications between modules - I'd love to have an IR or low power radio link between modules so that there are fewer penetrations for wiring (or none). This would allow me to reconfigure the ROV quickly.
