Re: Applying external loads to Inverse Dynamics does not seem to make a difference

Thank you for the answer Nicos. Your screenshot made me realize I was plotting the wrong data this entire time. What confused me was the "IDResults" that appears after ID tools finishes, I was sure it includes, well, ID results. Instead it's just a copy of the "IKResults" with a different name, whic...

Re: Applying external loads to Inverse Dynamics does not seem to make a difference

Hello, Sorry for the late reply, it took my a while to get back to the subject and fix my scripts for generating forces. Here's an example I found with both feet starting on the pad and I think there's alway at least one foot touching the pad. Forces should apply correctly for both feet now. I do tr...

Re: Applying external loads to Inverse Dynamics does not seem to make a difference

Files were too large to attach so I include a google drive link. Skeleton includes additional markers that need to be disabled when running IK tool but I added the IK result file as well, so it's not necessary. https://drive.google.com/drive/folders/17A7k9B__NecsHQ29w1hJwPHIfQc0vVo5?usp=sharing I ju...

Re: Applying external loads to Inverse Dynamics does not seem to make a difference

Thank you for the reply. I have two external forces set up, one for each foot. It's true that forces for left foot are zero because I still have issues to resolve with my force pad. However, forces for the right foot, and they should be set up correctly (same as for left food, just different columns...

Re: Applying external loads to Inverse Dynamics does not seem to make a difference

Here's the mot file with forces. It's rather simple but I figured it would make some kind of difference.
I had to compress it to fit here

Applying external loads to Inverse Dynamics does not seem to make a difference

I generated a simplified reaction force for two feet of a full body model. It looks correct in the visualizer. 1.jpg Here's how my xml is set up. 2.jpg After running ID I use the plotter to compare right knee_angle_r from IDresults with the same joint but running ID without external loads. I get two...
