    Has anyone looked at the D-Box platform concept.
    It would seems that with 3 fairly inexpensive linear actuators capable of 2/s at 40lbs and 3 springs with a constant of 25 to 50 lbs/in, you should easily be able to get a platform with 3DOF Heave,pitch, roll that can produce 6 to 12 degrees of pitch and roll plus 2 inches of heave.

    I am looking to focus on more range in the roll and pitch and leave heave for the i-vibe seat (which fakes it not really motion though). I did not realize D-box goes 12 degrees? do you mean 6 on each side? 12 total the whole range?

    Anyway D-box is an intereting idea that is only limited by the thousands of dollars cost!!!

    I think these 200 lbs 1.5 sec. would be the ones that I would use if this was attemped.

    here is a 40 lbs that is .25 sec faster

    ego is using some of this brand I think. I have not purchased as I am trying to see what I can do with the 16-$60 wiper motor style first.

    In any event it seems that you could hook these to a seat and have just as good of a lower cost solution. Would not vibrate as fast as the D-box but for vibrations you might as well go with a vibe seat...really only talking motions here so I think something acceptable could be done.

    I am unfamiliar with the 3 25 to 50 lbs/in spring requirement.

    What are they needed for? Are they taking some of the load off returning the motor to a centered poistion from the load it might take when all the way down? would that not cause more resistance to the opposing motors to compress them in the first place? I understand spring need with cable tension and such, but not so much so for linear motion assistance because of their worm gears

    Can you elaborate your idea.
