RC Submarine adjustable ballast

Adjustable Ballast.

Adjustable ballast for a homemade RC submarine. This video shows the inner workings of how this ballast works. Test so far are a good indicator that the ballast will work great in a live underwater test.

    Very nice!
    Elegant solution.

    The point is to balance the sub close to neutral boyancy so that the small change provided by the syringes will adjust the “float level”. This would allow for very fine control and might even allow that 3ft submerged neutral boyancy float that is so hard to achieve.

    I think there might be a small unbalance or binding in one of your gears though, causing the gagagagaga kind of drive.

    it actiuely does work u might need a bigger engine and the water it moves around is not that mutch but it will work and if u dont wat an 2000$ remote controller becouse of all the valves and channels it uses if u got compressed air this is a great solution i got my self a waterpump connected to a pvc pipe witch air in it if i let the pump run (6m watercollum) it compresses the air in the pvc pipe and lets water flow in and if i turn the pump off the compressed air will aumateacley push the water

    if you are going to place this on your dream submarine mate this does not seem to work. the SYRINGE that you use are too small and eats a lot of space and not big enough to contain water to make your project to sink and at the same time to float. the motor is heavier and seems to require DC 12V supply.try working on compressed air from an air tank or maybe a vacuum tube ( sort like piston ) maybe that will work.

    Is a “surplus” motor from a small printer. Is equal to a standard “speed 400” but it works at 12V.

    If you go to the RC forum indicated (miliamperios)in video and search for “tgnjkl submarino” you will find all information about it and the homemade schematic diagrams of a complete failsafe system to prevent lost of submarine returning it automatically to surface if an internal errors occurs or the RC signal is not good. If you have any question do not hesitate contact me by e-mail (you will found it in the Rc forum)

    ok just thought to make it proportional would be easier. if you put it on a slider on your transmitter you also know how far the “pumps” have moved. but still you could put it on a failsave channel to make the boat rise, just in case of ..

    The motor of the …
    The motor of the tank is controlled by a channel of the command RC. When descend the lever, the tank itself full of water slowly, when to rise the lever the tank is emptied also slowly, when leave the lever in the center the motor does not move and you can adjust the weight of the ballast, leaving the submarine to the depth desired. The endswitches are only to disconnect the motor once arrive at max. travel and to protect all the mechanism.

    hi ehm this one …
    hi ehm this one only goes full up or full down … i had the same idea, but instead if using endswitches you can also use a linear potentiometer. if you attach it to a servo-electronic, it will also drive the engine(provided the servo was big enough to handle the current of your motor) like this you get a proportional channel for the depth! please tell me if my idea worked 😉
