    Hello,
    i wonder why there is no diy of a YAW VR? In principle 3 motors and a hemisphere are enough to build this device. Or is the software implementation more difficult than with a "conventional" construction using wiper motors?

    best regards,
    Hans

    My Motion Simulator:
    3DOF, DC motor, JRK
    There is nothing stopping someone from building a spherical style sim, it is probably more a question of cost and complexity Vs limited output, as in someways even a basic 2DOF offers more precise control of movement and greater design flexibility, in a far simpler package.

    There is no issue on the software side.

    I thought the Yaw VR was pretty innovative when I first looked at it. But as I learn more about motion sim, I am less enthused by some of the trade-offs. The main thing I question is how the center of rotation is dictated by the sphere radius, the design give lots of motion travel near the base but gets much less as you near the center of the sphere. I think it takes away from the goal of tricking the inner ear if your head feels the least amount of motion. If the radius is large enough, it will feel like being on a swing compared to a seat mover which typically has the center of rotation under the seat. The seat mover then give your head more motion which seem like an advantage.
