Do You Want to Build a Lego Submarine?

Building a LEGO submarine sounds like an exciting project, especially with all the intricate details involved. The latest creation by 'Your Name' uses innovative components and clever designs to make it functional and visually appealing.

One of the key features is its connection to a Raspberry Pi Zero 2 W via I2C, which allows for seamless communication between the two. To control the submarine's buoyancy, LEGO gears were fitted to a syringe that adjusts the pressure accordingly. An absolute pressure sensor measures the depth of the submarine, making it possible to track its movements.

The submarine's transparent acrylic case is a marvel in itself, with precision-cut cylinders and rubber seals ensuring a waterproof environment. The end pieces fit together tightly, creating an invisible seal that prevents water from entering the chamber.

Wireless LAN connectivity proved to be invaluable during the development process, allowing 'Your Name' to tweak the PID parameters and update Python code without having to physically connect to the Pi Zero 2 W via USB. This saved a significant amount of time and effort, especially when working with precision components in a controlled environment.

The control loop is also an important aspect of this project, which relies on Raspberry Pi's capabilities to accurately measure and compensate for changing speed, location, and pressure levels. The use of LEGO EV3 motors containing tachometers allows for precise measurement of piston positions, making it easier to control the submarine's movements.

The design has undergone several iterations, with previous versions using propellers, a balloon, an air compressor, and a piston ballast to adjust buoyancy. However, this latest iteration settles on a more stable setup that doesn't compress under pressure when submerged.

This fourth LEGO submarine design by 'Your Name' showcases their dedication to innovation and attention to detail in creating functional and visually stunning models. With its impressive features and capabilities, it's no wonder that building a LEGO submarine has become an exciting challenge for enthusiasts around the world.
