FPV Contest 2022: Turbo Super Submarine

The projects presented on these pages frequently dominate the air, the ground, the rails and even the waves, but very rarely the depths. Building a submarine is difficult, and therefore it is a challenge that is not taken up by everyone, but by the bravest builders. That didn't deter [Timo], however, from building what looks like a very nice underwater ROV.

The design is quite simple, with a PVC tube frame supporting thrusters for maneuvering, and a central tube compartment for electronics and a camera. Control and power are via a wired connection, and there's a companion controller containing a Pi Pico interfaced to a PlayStation controller.

So far, the craft is a work in progress, and it's engaged in a battle with water pressure to stay dry inside. The fittings are all 3D printed, which means a constant battle with distorted prints and collapsing infill. He doesn't give up, however, and regains his enthusiasm while working on the ground controller.

We can't wait to see this project finished, in the meantime, if you're thirsty for more underwater projects, take a look at the glider that won the 2017 Hackaday award.
