Advice/help needed for RC submarine

Hi there, Im designing an RC submarine and am a complete beginner with no coding experience. I need advice on how to code and connect my regular RC electronics and controls through a 45-60m fathom tether and fathom-x boards, as well as what parts I would need. It needs multiple systems, including 2 servos for controlling the rudders, a main propulsion motor and ESC, syringe based ballast systems and depth holding, a high definition FPV camera, and potentially a way to launch multiple wire controlled rc torpedo mocks one at a time. Does anyone know how I might be able to achieve this? I was also wondering if anyone knew of a company or service who would potentially be able to do this.

Thanks,

Wayne

Hi @16345, welcome to the forum :slight_smile:

This seems like a confused approach. Fathom-X boards are intended for ethernet-based communication, so connecting them to RC electronics is not straightforward. You would need some kind of microcontroller board or computer to convert the RC signals into ethernet, and then possibly back on the other side, which seems a fair amount more complicated than having some kind of onboard computer that communicates ethernet with the topside, and passes on commands to a flight controller board running an autopilot firmware.

Who is defining these needs? Is this part of a school or research project, or a hobby project that you’ve decided you want to explore those concepts through?

Check out this guy, he has some cool videos that could help get you started. these are untethered thought, and use off the shelf RC parts. so they don’t do much below the surface. if you’re interested in going deeper, than I think you just want to build a tethered ROV, and that’s a much different build.
