I am a mechanical engineering student investigating the effects of altering squat stance for a barbell squat. I am using the squat model and am unsure how to move the arms into a position to hold the barbell, with the forearms perpendicular to the ground. Does anyone know an easy way to do this? Many thanks
Hi @stchloe - and welcome to the forum!
The squat model have a
Mannequin.any file where you can alter the load position of the arms.
It also have a
RightArmArmDrivers.any and a
LeftArmDrivers.any file that specify what the arms do during the simulation - it defaults to just keeping the posture defined in the mannequin file.
If you haven't seen our tutorials here is a link:
I would suggest to complete number 2, 3 and 11 - that should give some ideas and example of most of what you need.
Thanks for the reply. I have managed to alter the elbows and wrists but for some reason cannot alter the sternoclavicular protraction, rotation or elevation. These seem to be controlled by a clavicular rhythm but I cannot find how to turn this off so that I can input the values I want.
Those degree of freedom are part of the shoulder rhythm and you need to disable the
BM_ARM_SHOULDER_RHYTHM which you can find in the
This is extremely helpful, thank you very much!
Another issue I seem to have encountered is that my libdef.any file has corrupted and I cannot find the correct original version required to run the model.
Do you happen to know where I can download this individual file without having to download the entire AMMR again?
You should be able to find a complete version of your AMMR in the AnyBody install directory.
It is normaly located at
C:\Program Files\AnyBody Technology\AnyBody.7.3\AMMR where the version number is of course dependent on your version.
