Symbolic jacobian of an arm
Hi all,
I've a 7 DOF arm described in .xacro format and I would like to extrapolate its jacobian in symbolic form (not numerical angle values in the matrix ).
I tried to use KDL for this scope, and I was able to obtain the jacobian of this arm but in a numerical form. That is, during a gazebo simulation, I could read the values of each angles, insert them in the jacobian matrix with a specific kdl command, and obtain the jacobian matrix on every gazebo step time.
That's ok, but if I have another target in which I need the symbolic for of this jacobian from which extrapolate other matrix (inertial, coriolis ecc..), I'm not able to do this. (For example if I want to control my arm in a particular way in which I need the dynamic expression of the system).
Has anyone every have this problem? Is there a method with kdl or another software that I can use?
Thank you!
Hi Did you resolved your problem? I have almost the same problem as you I want to use Coriolis vector in my controller, do you have any suggestion for me? I have read many things in last days and I just got confused. I have tried to use DART library but till now it was not helpful, I really appreciate if you can help me. Thanks.
