Hello
Thank you for your great video.
I have a question, at 00:52 of the video are you sure the formulas are correct cuz all of the Angeles multiply by L1 and I think L2 & L3 are missing!

Thanks for another really useful tutorial. But I'm afraid I got lost at one point at 3>30 where you list the terms for DLS there is the term I which you don't tell us what that is. (Maybe it's some constant of something you would assume we would just know, but I'm self taught so there are big things I'm missing. What is I? Thanks for a really useful series of videos on ROS! I look forward to absorbing them all (if I can).

So this is simulating a an arm mechanism with 3 segments of length l_1, l_2, l_3 respectively.
I wonder how hard it would be to simulate the kinematics for a parallel robot like a delta robot.
As always, your videos are a great help.
