Functional prototype with gear drive

- Session summary:
Improvement session following the functional prototype. We strengthened the assembly by adding protections for the electronics and integrating a more advanced gear-based propulsion mechanism.

- What we did:
We designed and 3D printed custom boxes to properly secure the various Arduino boards inside the boat, improving both the protection and organization of the components.
We also replaced the propulsion system with a gear-driven mechanism: two cogwheels now transmit the movement of the motor to the propellers. This system offers better control and greater mechanical complexity.

- Results / Progress:
The boat is still running smoothly after these modifications. Components are better secured and protected, and the gear system works as intended, making movement smoother and more realistic. The project now features a more robust and realistic propulsion system.

- What remains to be done:
Finalize the documentation of these improvements, including schematics and design files for the boxes and gears. Gather feedback on mechanical integration and performance.

- What we're going to do next (future project):
For a future version, the aim will be to use a fully waterproof 3D-printed hull (like the V2 version) to ensure long-lasting operation and better water resistance.
