Inverse kinematics - no pelvis movement

[Swathi Gangaraju]

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 helpful.

Thank you

Kind Regards,
Swathi

Hi Swathi,

IMUs typically report orientations only and no translations. If you check the OpenSense example/demo you'll see that the translations are unchanged throughout the motion.

Hope this explains,

Thank you Ayman. This helped.

Hello!

Is there anyway however to utilize the acceleration data from an IMU to determine the pelvix_tx, ty, and tz values in IK?

Hello!
We're facing the same issue, is it possible to allow pelvis_ty in the model driven by imu data?

Thank you
Cecilia
