Building a Lego-powered Submarine 3.0 - balloon and compressor

8 МЛН рет қаралды3 300

    Depth control is done with an air-filled balloon and a Lego-compressor. Steering is done by turning the propeller direction with the help of linear magnetic coupling. Otherwise it's more of the same as before. Swimming pool and lake tests at the end. Enjoy!

    Specs:
    Displacement: 2.35 kg (5.2 lb)
    Test depth: 6 m (20 ft)
    Hull: glass jar (IKEA 365+ 1.7l), plastic lid
    Balloon: latex water balloon for kids
    Motors: 2x Lego PF L-motor (88003-1), 1x Lego PF Servo motor (88004-1)
    Compressor parts: Lego pneumetic pump small V2 (bb0875), Lego pneumatic switch (bb0874), Lego Gear 24 Tooth Clutch (60c01), Lego Hose Pneumatic 4mm (21825)
    Magnetic couplings: K&J Magnetics D34-N52 neodymium magnet, TapeCase 423-5 UHMW Tape
    Propeller: Lego Propeller 3 Blade with 24t Gear (2740c01)
    Radio control: 27 MHz controller dissembled from a toy submarine (Zantec Mini RC U Boot), L298 H-bridge to drive motors
    Power supply: 9V Lego battery box for the motors, 3.7V Li-Po for the radio
    Pressure sensors: Lego Manometer (64065), Jolly Logic Altimeter One

    Note: The depth control I use here is called RCABS or Recirculated compressed air ballast system.

      could the balloon potentially break on the way up due to it expanding when rising?

      Next will be aircraft carrier with operational air plane, maybe build an air plane first.

        When you're a bored engineer but you have a bucket of Legos:

    57. Aidan Shipley

      When I was a kid, playing with bionicles, I would take the really loose "axles", put it between my teeth and twist so that it stayed in place better. Just cutting up the outsides of it to produce more friction between the axle and the piece I needed it to stay in helped a ton (especially with their swords). You could probably find another method to use besides your own teeth, but I think it could help out a lot in those situations where you really don't want them to fall out!

      Lego actually made 4 units long axle that don't slip out so easily, it is not at all that pricey to try and get hold of them.

      This is awesome. I saw someone printing boats, they used syringes with tubes, connected to a servo arm to act as a ballast. Super simple and genius. Like building subs with legos. Genius.

      where are you getting all these stuffs

    84. Space Elf Downlink

      I still am not grasping the depth control, is the balloon pulling it up or is the act of pulling a light vacuum in the main chamber causing lift. of course on a different note magnetic drive from dry side to wet side, just like the D5 pumps in my PC water cooling. the impeller on the wet side is driven magnetically.

    89. Special EDy

      You don't need a pressure vessel. Just fill the mechanical/electrical Lego compartment with mineral or vegetable oil instead of air. Oil is incompressible, non-conductive, and boyant.

      1. PhiƖiþp Ʀɛichɱutħ

        Then you get oil in all your Lego motors, that can't be good for them.

      11:10 the fish looks interested for your submarine

    97. Kragoth

      Could you explain why inflating the balloon changes the depth? Isn't it just putting air that's inside the container into the balloon? I'm sure the solution is obvious once you understand the mechanics behind it. I'm just not understanding it atm.

      1. Kragoth

        @PyramidSchema thanks 🙂

      2. PyramidSchema

        The air weighs the same whether it is in the balloon or the container, but when the air is in the balloon the balloon expands, increasing the volume of the vehicle and the amount of water it displaces. When the volume/displacement increases but the weigh remains the same the vehicle rises, when the volume shrinks but the weight remains the same it sinks.

    98. StarLevi

      I love how the whole video is an experiment, that even the failures are documented. Interesting watch! Keep it up
