Obtaining muscle force components

Hello everyone. I am working with MocoInverse, in concrete I've built a 4-bars mechanism, in which I've implemented two muscles, each of them is attached to one side of the input bar, as seen in the picture. https://i.ibb.co/h24pFS7/cuatro-barras-musculo.jpg I have coded a Muscle Driven problem, usi...

Re: Trouble with Inverse Dynamics with exoskeletons

Hi Nicholas, Thank you very much for your response. Yes, I added Coordinate Actuators to every coordinate created in the exoskeleton, but the optimization algorithm never stops. Maybe is it related to the predetermined tolerance? Aproximately at 300 iterations, the value of cost function barely chan...

Trouble with Inverse Dynamics with exoskeletons

Hello everyone. My name is Guillermo, and I started to work with OpenSim and Moco some months ago. I would like to ask for some piece of help for a project I'm involved in. I am working with the 3D model, subject_walk_armless.osim, and I've built an exoskeleton on it, as it can be seen in the pictur...

Re: Mechanically Passive Shoulder Exoskeleton Model Public Forum

Hello everyone. My name is Guillermo, I am an engineer from the University of Sevilla, Spain. For my End of Master Project, I'm designing an exoskeleton for upper limbs. I've been trying to open this model but I receive this message: MovingPathPoint:: Components of the path point location must depen...
