Range of motion

Main Forum

hi,

how can I control the range of motion for joints (e.g. Knee flexion) in a body model with muscles!

is there any specific file to put the values of the range of motion in (directly) like in the body model without muscles (jointmuscle file),or the changes should be made in the joints definitions?

do the muscles control the range of motion?

please explain this to me.

Regards,
Zayd

Hi Zayd,

Basically AnyBody is running Inverse Dynamics so the motion is input to the model. This means that you can not set a limit on the joints angles, since the joint angles(or similar) is provided as input.

It is possible to let AnyBody determine the motion and take into account joint limits, but this requires an extra optimization loop and a good optimization criteria that can be used to determine the motion.
