How do I find the forward kinematics of a 3R manipulator using DH parameters?

    The final equations are given below. I want to know the procedure. Please help.">How to find the forward kinematics of a 3R manipulator using DH parameters? The final equations are given below. I want to know the procedure. Please help.
    x = cos θ1(L2 cos θ2 + L3 cos θ23) y = sin θ1(L2 cos θ2 + L3 cos θ23) z = L1 + L2 sin θ2 + L3 sin θ23, where θ23 = θ2 + θ3.

    Hi,


    I have similar problems in my Masters as well. To understand DH parameter better, try this video in youtube(Denavit-Hartenberg Reference Frame Layout), I find that easy to understand.


    Cheers :yesyesyes:,
