Add dof to fingers
Posted: Wed Apr 05, 2017 11:05 pm
Hi,
I'm trying to add more dofs to the fingers in the forearm.osim model. I was trying to modify the xml code based on the customized joint settings for the index finger. Right now, there are two dofs are added to the middle finger. But my problem is the lateral and flex movement of middle finger are improper, because the middle finger is moving apart with the palm when I change the angles of the lateral and flex. The middle finger is not only rotating but also translating.
I read a former topic in the forum which was talking about the same situation with mine, I tried to change the location_in_parent but I don't think it helps my problem, because when I change the location_in_parent for index finger, the only difference with unchanged index finger is the rotating center. After changing location_in_parent, the index finger is still rotating without translating. But the middle finger rotate with translate.
I also tried to change the rotation axis, but it still not move properly.
Would you please let me know which part should I change to make the middle finger and other fingers move like the build-in index finger? Thank you very much!
