Need method to track 6DOF

  1. Mar 6, 2009 #1
    Hi everyone!

    I try to build a device that can track 6 degree of freedom of itself but lacking a method provide enough accuracy. So I'm here asking you for help

    The device's size needed to be about a cell phone or smaller
    The accuracy needed to be enough for detect movement about 1/10 mm or smaller on each axis
    It only needed to move on small area, about 20cm on each axis
    And the cost is important, too, my goal is to keep the solution under 100$, if possible

    If you have any advice, thank you!

    Can you use rods to triangulate on the (x,y,z) position, and rotational shaft encoders to give you the rotations? Or is your intention to make this a non-contact system? What are the physical constraints?
