Calculation of COP(center of pressure) for each foot


I made a simple example using the conditional contact element from the gait full body example in the AnyBody repository.

I’d like to ask you whether there is a way to calculate the COP(center of pressure) for each foot from the active conditional contact elements.

I’d like to get your advice.

Best regards,

Hi Moonki,

This is possible, please do the following:

[li]For each foot create a virtual force plate segment and let the contact act on these segments.
[/li][li]Setup a reaction force for all six dof in the center of the plate, then basically you have measured the forces just like a forceplatetype2 plate.
[/li][li]Then you need to calculate the COP which is the point where the moments are zero except around a normal axis to the plate.
[/li][li]An example on how to calculate this can be seen in the file Toolbox/mocap/Forceplate2.any

I am curious how did the results look like i did not run the model .

Best regards

Hi Søren,

Thanks for your advice. I will upload the modified example when I complete to build the model according to your advice.

Best regards,
