Articulated Boom Lift Vector Loop Analysis

Your Matlab simulation tutorials are amazing! Could you consider making a playlist on problem-solving using Matlab? I'm sure it would help many of us! Thanks!

I have a Matlab Tutorials playlist here th-cam.com/play/PLTMo3nrl2KWbeCx8-OGfrMHcFOUSjyk4D.html that goes into solving vector loop equations and programming simulations, but I can certainly add more videos to it!

Is the velocity vectors required to animate it? Or can you just use a varying position vector for animation

[@dynamicsandkinematics]

You can use changing position vectors for the input. To calculate the unknown angles, you do need to use the Jacobian with Newton's method in a while loop. The easiest way to get the Jacobian is through velocity, but you can also just take partial derivatives or use the formulas explained in this video: th-cam.com/video/mBTLWPXTckU/w-d-xo.html . An example of using Newton's method to solve for unknown angles in code is here: th-cam.com/video/_Ikq9nQTrz4/w-d-xo.html

@@dynamicsandkinematics Thanks for the quick reply. I was thinking of using Gauss-Seidel to solve the set of equations, would that be possible?

[@dynamicsandkinematics]

Yes, any iterative method for solving systems of linear equations should work.
