Problems when setting initial conditions


I have modified the seatedhuman demo, adding a steering wheel to simulate steering and it worked well. Referring to the pedal demo, I added a pedal located in the desired position and changed the pelvis joint. When setting initial conditions, no system error occurred, but the pedal was located strangely on the back of the head so the right leg was in a strange position as well.
I wonder what caused this problem?



Attached please find my modified version of your model.

First of all, your hinge joint location was wrong.

Please try to figure out what I have changed on your original model.

I just tried to make your model working in terms of kinematics.

So please review this model carefully in terms of kinetics.

I hope this may be helpful to you.

Best regards,

Hi Moonki,

Many thanks for your help. It seems that I have misunderstood the reference frame of the hinge.
I will keep working on it and try more efforts to improve it.
