    Hi people !
    I'm planning ( finally ) to purchase an SK1 kit 3DOF seat mover simulator from simukit , it is the best i can choose for budget reasons ( obviously ), and for space in my VR room .
    I need something compact and easy to stock when not used.
    But i want to add to the existing design a fourth axis to have a 4DOF device for sway movement .
    What is the best design to use in this case ?
    Thank you.

    I found what i will make : a simple motor attached to the SK1 frame with a lever attached to an underlying frame , and a chair swivel attached to the front of the SK1 frame and to the underlying one .
    At the rear part of the SK1 frame there will be two ball beared wheels that will roll on the underlying frame.
    Another option is to put the motor on the U-Frame , in this case this will save some weight , perhaps this design is better ...
