    Hi all,
    I've built a Compact Car Rig out of wood and move it with 4 power steering motors.
    It's working ok powerfull enough to throw you around at the right time.
    Running on SimTools and SMC3.
    I've setup the Traction loss in an unusual way and haven't seen it done this way before.
    I someone has already done it this way please tell me.
    If you have any questions i'd be glad to answer all.

    Pictures soon

    Please do tell us what power steering motors you used and if any mods were required to use them,

    That is one gnarly, care to add some detail about it?

    Sure thanks its moved by renault clio 2 power steerers hardly any mods. You need a welder and a grinder. My aim is to use as little parts as possible and I use practically all the metal that supports the steering column by cutting it and folding it to make supports for the motors. The long shaft is held by a pin that just pops out and with a rubber hose I connected to a potentiometer. The rubber hose allows the potentiometer to spin when the engine goes crazy in tuning mode.

    Hi, first laps completed and all is fine. Very happy. 4dof is working great.
    Setup details;
    4 motors at each corner.
    2 tied rods added in front for guiding.
    I ve imagined this setup for the rear being able to acheive pitch heave and traction loss.
    Front can pitch heave and is responsible for the roll alone.
    If you have already seen this approach please tell me because I woke up one morning with this idea
    and don't know if it already has been done ?
    The big advantage is you have two rear motors working for pitch and heave and they both are used for traction loss giving plenty of power through the seat in every motion.
