    My Motion Simulator:
    3DOF
    Greetings to the Motion Community!

    I have been working on a 3DOF motion simulator with pitch and roll axes centered very near the inner ear.

    The whole reasoning behind this :

    low axes of rotation of pitch and roll are convenient to build ... but make the head of the user describe large arcs during transient rotations, registering as inverted translations which are confusing for the inner ear.

    Right now its 3DOF to keep price accessible and also because 3DOF is already massively immersive... (but it can be expanded to 6DOF without problem)

    So I know there remains a few minor kinks to iron out, but here is it in action :

    Cheers

    Cool. I like how the structure works perfect for the monitor. Can you show more of the build?
