Inverse Kinematics Error

Post by Zheqi Hu » Sat Jan 06, 2018 9:41 am

Hi,

I am now using IK Tool to calculate joint kinematics. During calculation, motions of all the segments are correct except pelvis. The relative positions of markers to the model keep the same as set. I have checked coordinates data with 'preview experimental data', and the coordinates data was fine. What could lead this problem?

Any advice would be helpful.

Thanks.

I'm not sure I completely understand the issue. Perhaps you could upload an image to help explain what's happening? Based on your description, it sounds like the pelvis coordinates might be locked.
