We’ve seen Lego subs built before, even including missiles. It’s not winning any races anytime soon, but it’s a functional underwater explorer that we’d love to take down the lake ourselves sometime. In testing, the sub performs admirably, with a few final tweaks necessary to improve the performance of the propellers. An existing RC submarine is cannabilized for parts, providing the necessary radio control hardware. A large syringe is used as a ballast tank, with Lego motors used to actuate the tank and provide propulsion and steering. The video steps through the process of sealing the hull itself, before dealing with sealing the rotating propeller shafts. That didn’t phase, however, and thus a Lego sub was born. Water ingress can ruin your project, and there’s always the possibility of it sinking to the bottom, never to return. kelvinA wrote a comment on Kinetic Sculpture.Submarines are universally considered cool, but bring several challenges to the RC modeller that aren’t there with land and air builds.kelvinA wrote a comment on project log Theoretical approach to an extended battery.
