MATLAB: Articulated arm

articulated armrobotic armsendit2me

hello friends I am a student of electrical engineering and I have to do a project in matlab arm Simulation

I wonder if I could receive the code of this example or one like it for a guide to start thanks in advance

Check this answer for a starting point.

 A_02 = simplify( A_01(q1)*A_12(q2));

That returns an array, not a function handle or symbolic function.

 A_03 = simplify(A_02(q2)*A_23(d3));

With A_02 being an array, q2 is attempting to index it.

A_02 involves two variables, so I cannot predict which variable you want q2 to substitute for (function handle case.)

This is very close to that you need:
