I do the IK first and then the ID. After modifying the stiffness of the spring, I carry out a new study of IK and ID, saving it in different files and comparing the moment of flexion in the elbow, resulting in that they are exactly the same, which I do not understand, according to which the kinemati...

Hi, I'm trying to see how using an exoskeleton when doing a flexion / extension movement affects the elbow, the problem is that when modifying the spring stiffness, I always get the same torque at the elbow. exo.png elbow flexion moment.png Logically, by modifying the spring stiffness, you should ge...

Thank you very much, it has been of great help

Hi, I have a doubt.
path spring works like a tension or compression spring?

I need the spring to work on traction.
Thank you

Thank you very much for the reply. I'm trying with some restrictions, although I have another question. I have tried to define a constraintball but when loading the model it does not recognize the restriction. The code that I have used is the following: <ConstraintSet name="constraintset"> <objects>...

Hello, I have defined 1 personalized articulation between the blue plate and the humerus, and between the yellow plate and the ulna bone. The problem is that when defining a new articulation between the yellow and blue plates, the following error message appears, and the model is not loaded. ejemplo...

I want to use a balljoint, but I can not find an example. Could someone give me an example of how you should write the code for a balljoint?
Thank you

Thanks for your answers, I am trying to eliminate the weldjoint and use less restrictive customjoint, to see if I reduce the assembly error.

Good afternoon, I added different solids to the Dynamic Arm Simulator model. The problem is that when doing the IK study the following error message appears: InverseKinematicsTool Failed: AssemblySolver::assemble() Failed: SimTK Exception thrown at assembler.cpp:871: Method Assembler::assemble() fai...

thanks, looking at the GUI I think I found the solution, how did you mention
