Need Help On car steering (Toy)

  1. May 1, 2007 #1
    Hi guys.
    i need help to make a steering mechanism for a toy car.
    the car should be able to drive forward and reverse and can be turned. car should be controled by a wired remote control with maximum of 3 wires.
    this seems to easy, but I'm still in the first year and do not have knoledge about these stuffs.
    my main problem is how to make a steering mechanism and how to manage control with 3 wires.

    buy a motor attached to a gearbox for extra torque, one way is spring loaded to return to center with a flat toothed bar, next is a teardrop gear with rubber band slippage, next would be a spiral gear with no springs. as far as the wires go you'd have to have a split supply and use dpdt spring return to center switches wired with the outer poles forming an x to change polarity.
