  • error propagation in forward kinematics

    Dear Biomch-L Subscribers:

    I am wondering if anyone has done or is aware of any work dealing with the
    following problem (I personally call it error propagation problem) in
    performing forward kinematics. In movement synthesis or simulation,
    suppose Cartesian coordinates of the joints are being derived from segment
    angles using recursive kinematics; even if comparable errors were made in
    the angles (w.r.t observation), errors in joint coordinates would increase
    along the direction of forward kinematics (e.g., proximal to distal). I
    would like to find out if there exists a technique to circumvent this
    problem, say to evenly distribute the errors.

    Thanks for your attention. I will provide a summary of responses.
