I have considered building a submersible remotely operated vehicle for a long time, but now I live in an apartment with a swimming pool, so testing will be easier than using natural water bodies. The designs I wanted to try were to create a vehicle that was easy to seal but sealed extremely soundly and one that could operate from audible commands in the water. Every submarine video I see on YouTube shows a buoy with a radio antenna inside, and I want something that operates completely submerged. Sound waves do not fail in water the same way as radio, but I suspect interference will still be an issue, especially in the ocean.
There are numerous things I had to create for a working submarine, and the first was magnetically coupled propellers. Typical propeller arrangements housed their motors inside the sub's body, and the axle passed through a gland. Some new designs used brushless motors exposed to the water, and only a wire needed to go through a sealed hull hole. The plan was to spin a wheel studded with magnets inside a cylindrical tube and fit a propeller around that tube. The two will lock together with no moving parts passing through the hull.
I sketched the idea with a boat hull, which regrettably looked like a bathtub. Underneath were a couple of rounded chambers that contained motors and orange magnet wheels. The motors would spin in opposite directions to keep the movement from tipping the boat. For the first prototype, I will not print the hull, but I plan to install the connecting stem into an empty bottle or something similarly buoyant.
