Hi,
I am interested in studying the effect of a time-varying assistive force (F) applied on the pelvis when walking. This force F could be a controller since I can define F as a function of state. Can I implement a controller and attach it to a model en then use this model directly in Moco?
I found a c++ example of how to create a custom controller and attach it to a model : https://simtk-confluence.stanford.edu:8 ... r+Part+One), can this be done in Matlab as well?
Thank you for your help!

Re: Controller with moco
Time-varying forces can potentially be modeled with OpenSim's PrescribedForce component, which would not require a Controller and could be used in Moco right now.
Moco does not support OpenSim Controllers right now, but this is one of the main features we hope to add over the next few months.
To achieve what you want, you do not need a *custom* controller; you should be able to use OpenSim's PrescribedController, which allows you to specify time-varying functions (including splines) to define your control signal.
If you find that you *do* want to create a *custom* controller, that must be done in C++, not Matlab.
