Re: Insanely huge residuals and joint torque

I've been waiting for my data to reprocess on AddBiomechanics for over a week now. I've force-reprocessed and also created a new subject and re-uploaded data. They're stuck in "Queued on SLURM cluster", so I don't know if the torques are still in the 10^4 range. I will reply again if they do end up ...

Re: Insanely huge residuals and joint torque

Hi Nick, Thanks for the tip. I was able to visualize the GRFs with the motions and it appears that the forces are being applied at the proper location and not suddenly deviating away from the foot. GRFs look nearly identical between exo and no-exo conditions; the exo is only ~1kg so similar GRFs is ...

Re: Insanely huge residuals and joint torque

Hi Nick, Thanks for your response. I've answered your questions below. 1.) Yes, the model does have modified mass properties to model the exo mass. The mass of the exo is about 1kg and it is worn on the shank bilaterally. <Body name="r_exo"> <!--The geometry used to display the axes of this Frame.--...

Insanely huge residuals and joint torque

Hi, I recently used AddBiomechanics to scale and run IK/ID on a custom lower body model based on Rajagopal 2015, used with experimental data collected during walking, fast walking, and incline walking under two conditions: 1.) no exoskeleton and 2.) exoskeleton. My IK/ID results look good for the no...

Re: Coordinate actuator Inverse dynamics or RRA??

Hi Lynn,

I'm working on a similar project, and I'm wondering what version of XML you used for the code you included for your solution in the model .osim file? I'm using version 4000 and the syntax is quite different from yours.

Help with adding Exoskeleton to Rajagopal Model

Hi everyone, I am trying to add bilateral active ankle exoskeletons to the Rajagopal 2015 model, in order to run IK, ID, and Static Optimization from experimental data. I'm adding the exo direcly into the .osim file. I've added the exo frame geometry as an object under <BodySet> with an attached .st...

Rajagopal - lower body only?

I'm relatively new to using OpenSim with experimental data I've collected myself. I'm trying to use the Rajagopal model to do IK and ID analysis on the lower body during walking under different speed, incline, and exoskeleton conditions. My question is: can I use the Rajagopal model with a lower-bod...
