Hi there

I am attempting to run through my pipeline with locked joints and I am not succeeding. I have successfully run without the joints locked and I am curious to see how it will affect my results if I lock the mtp and subtalar joints. However, I simply cannot get RRA or CMC to run with the joints locked.

I have set the Tasks to false, and that did not work, I then also removed the control constraints and actuator setting from their respective xml settings files and that also fails. Is there something I am missing?

Also, I noticed that RRA crashed (without the joints locked) if I did not filter the kinematics. I found this strange since I do not filter the kinematics for cmc (the resultant kinematics from RRA), and upon plotting they look very similar - the IK and the RRA results that is. Any comments here would be appreciated.

Regards,
Julian

You might want to look at Chris Dembia's "Simulated Assistive Devices for Loaded Walking" project (https://simtk.org/projects/assistloadwalk/). CMC was used with a model containing locked joints.
