Wired Wheel?

[naossoan]

Hi All,

I've been trying to make a bellcrank steering system for a car but I'm a newb when it comes to wiremod.

I can get all the pieces how I want and everything but I don't know how to do this part.

Here is a simple drawing. Yellow represents axis, Red represents axis'd rods, and the blue one is what I'm going to be talking about.



The blue rod, I want to wire it up so it will rotate say, 30 degrees anti-clockwise when I press 4 and 30 degrees clockwise when I press 6 and return to 0 when I'm not pressing anything.

Can anyone explain to me if this is possible, and how to wire it up? I mean I can understand I would need to make a wired wheel, or possibly a motor, have a dual input switch. I just don't know how to make the wheel move.

Thanks.

First I want to say good luck on the actual construction. I hope you're not going to try to make it small.

I think that a wired hydraulic would be your best bet. In that case you could make a simple E-gate to do the job for you, then have the inputs go to a wired keypad.

You would need to find out the length on the hydrolic at 0 then it's lengths at 30 and -30.

The E-gate might look something like this, assume that I measured the hydraulic and it is 16.4 units long at 0deg, 31.4 at 30deg, and 2.1 at -30deg. I am assuming that your tierods will be behind the wheel's axis.

Inputs: NumpadLeft NumpadRight
Outputs: Length

Length = 16.4
NumpadLeft == 1 -> Length = 31.4;
NumpadRight == 1 -> Length = 2.1;
NumpadLeft == 1 & NumpadRight == 1 -> Length = 16.4;


(this would be the perfect application for a wired stepping motor, but I'll keep dreaming about that one)
