    I am considering an idea for my upcoming 6DOF project that I wanted to run by the experts. I was wondering what you thought of designing a 6DOF rig so that the actuators are angled inward instead of outward. Here's an example Dureiken modeled:


    I see there being a few advantages to this type of design:

    1) The pedal platform extension and top platform enclosure are less likely to come into contact with the actuators. This means you can achieve much steeper angles with very few limits.

    2) The total space needed for this design should be about the same or even a little less than a hexapod because the top platform can never extend past the dimensions of the bottom hexagon (this would cause a singularity = the rig would collapse).

    3) The top platform will be much smaller, lighter, and more stable.

    So clearly the downside is the bottom of the platform will be larger, but overall the size isn't too bad thanks to the very compact foldback actuators I'll be using. My biggest concern is that this design may be more likely to cause a singularity if there is a power outage, but I have no experience with this and maybe I can design safeguards.

    I would very much appreciate any comments or suggestions before I attempt this type of design. Thanks in advance for your help!

    My Motion Simulator:
    2DOF, DC motor, Arduino, 6DOF
    some sims are built this way - it will be quite stable
