    Hi All
    I built a 3 screen rig based on 8020 aluminium approx. 8 months ago and I am now looking at adding 3DOF motion

    One of the questions I have (there's plenty but 1 to start) is whether it is best to keep the screens still and move peddles, shifter and wheel with the seat or move the screen too.

    I run both rFactor and iRacing and in both cases I note that the background general stays level - as it does in life.

    so by moving the screens it would seem a little unnatural, I do understand that perhaps it may negate motion sickness though not something I suffer from in a sim or car for that fact.

    Just looking for input from the forum to assist with the decision.

    Thanks in anticipation

    Regards
    Mike

    If you are planning to build a 3DOF (motion platform and not seat mover) you have to put all gadgets together onto the platform.

    Ok, forgive the lack of correct terms, still learning those

    I do not plan on going with flight sim at any point, braking, acceleration, roll left and right and traction slip - is this 3DOF? To that end the Wheel, Shifter and Seat can be secured to a common platform/rig and the motion equipment move this part of the platform/rig which to my way of thinking is 3DOF - perhaps not.

    I made allowances to add motion to the platform/rig and to either keep the screens fixed to the platform or separate to it dependent on whether or not its best to have the screens move with the platform or fixed to it.

    My Motion Simulator:
    DC motor, Arduino, 6DOF
    If you want to use all these DOFs you would have to go the 6DOF route...a 6DOF is very complicated due to the maths and hard to justify, if something goes wrong the rig will be destroyed faster than you can imagine...
    If you want to integrate the most needed DOFs for racing simulation (do not forget the cost), you could build a 2DOF seat mover plus an additional surge and traction loss table. If there is some more space you can add a separate heave which raises the immersion.
    The monitors have to be placed onto the surge table...the surge/traction loss table ergo is not the easiest way but IMO worth a try.

    Thanks for the input so far, clearly more research needed before stepping off.
