    Hello everyone,

    I'm putting together a home-made ROV, to be more precise an UROV
    (Underwater Remote Operated Vehicle). My device so far has very low level
    of sophistication but I want to build-up on it.

    I used PVC for the frame and bilge pumps for thrusters, not an original
    idea but sort'a works. I'd like to improve the controls. Now it has a
    cheap joystick for the horizontal controls and 2 push buttons for the
    up-down. The connections are lame, all the brown wires from the pumps to a
    wire strip in one box and all the black ones twist together in another box.
    Then 20 feet of #24 shielded cable with 8 conductors, one end with the ROV
    the other to the control box when 12V from a battery powers the whole thing.
    One 3amp fuse and that's it.

    Well I need better control... I don't think the distribution of power is
    even to the 6 thrusters. In order to go forward I need to activate two
    thrusters in the bow that are positioned about 45o. With the present
    connection the vehicle favors one side a lot more than the other.

    What kind of digital control would you add to this, I have BOE-bot from
    parallax and works so nicely, how would you merge both concepts, with no
    more than a couple hundred $'s ?

    Any ideas would be appreciated

    Gyros would be nice. I don't know what the BOE-bot thingie is, so I
    couldn't say what it's capable of.
