Hello Zakaria, It is not possible to get a model's underlying equations in symbolic form. Based upon what you have described I think you could work with the individual terms of the equations, to obtain those terms (i.e., coriolis etc) you would have to first set the model's state vector and then ex...

I created my script to change to Matlab array.
thank you so much for the code.

Salam, Hi everyone, I'm working on apply some control methods on the Arm model, in designing the sliding mode controller I need to get the matrices of equation of motion or state space of the model but I think the getting the matrices is better until now I got the mass matrix using simbody method ca...

For a few reasons, I ended up writing code in Matlab to get the gravity vectors without using the MEX interface. This way I don't need to have separate parallel instantiations of the model in C++ and Matlab. I have included the Matlab code below. I compared it to the output of my MEX interface code...

You can find many examples on the documentation page here: https://simtk-confluence.stanford.edu:8443/display/OpenSim/Examples+and+Tutorials One of the examples named "Simulation-Based Design..." could be helpful for your work. Thanks I created a PD controller to control the Arm using MATLAB now I'...

Hello everyone, I'm Zach, mechatronic student, I'm working on my thesis about Arm Exoskeleton and apply control method in controlling the Exo. I'm looking how can the Exoskeleton apply an external force on the Arm ? I'm using MATLAB but I can use python. if someone has a simple example about that it...
