Hi all, I am working on a forward simulation in the OpenSim-rl package and I need to change the integrator. The OpenSim Doxygen website provides good examples of how to implement this in python, but unfortunately, the OpenSim-rl package is not updated and does not include those functions. The functi...

Hi Carmicheal, Thank you for the reply. You are correct. I think the default integrator that the opensim_rl use, does not support "setIntegratorMaximumStepSize". I have been trying to use fixed-step size for the integrator with little success. I am a little confused on the process here. It turns out...

Hi all, I wanted to see how I can have more control over the integration step of the forward simulation in the python interface. I am working on this reflex-based OpenSim model that was published for the NeurIPS 2019 Learn to Move - Walk Challenge. https://github.com/stanfordnmbl/osim-rl/blob/master...

Hi Samuele, Thank you for the response. It is good to know that I can modify the xml file. However, since I want to run the model several times (i.e. 100 times), I was hoping to avoid making several .mot files. I ended up using the opensim.PrescribedForce() function, and it seems to be working fine....

I found this example:

It should hopefully help solve the problem.

Hi all, I am trying to add an external force perturbation to an OpenSim model. I was just wondering if there is an easy way to do this. I am working with a modified version of this reflex-based OpenSim model in Python that was published for the NeurIPS 2019 Learn to Move - Walk Challenge. https://gi...
