Inverse kinematics - no pelvis movement

Hai all, I have implemented a code in python for computing inverse kinematics using IMU sensors. I followed Al borno paper and code for the implementation. I am facing issue with Pelvis. There is no location change with pelvis while running simulations with OpenSense. Any input on this would be help...

IMU frame to OpenSim frame coordinate mapping

Hello, I am confused on how the coordinate system are changing from IMU frame to OpenSim frame. The below code is from the paper 'OpenSense: An open-source toolbox for Inertial-Measurement-Unit-based measurement of lower extremity kinematics over long durations'. Especially why there is rotation aro...

Import of quaternion using TimeSeriesTableQuaternion in python

Hello, I am using IMU other than Xsens and APDM. I have a csv file which contains quaternions of orientation. But I try to access the csv file using the below code. The code freezes for long time without any output. And I even tried many other methods which didn't work for me. import opensim as osim...
