Help with kinematic motion driver

Main Forum

Hi Everyone,
I’m a new Anybody user and I have some questions about a model construction. I would like to reproduce a real kinematic motion of TMJ. Kinematic motion of jaw data is defined as a three translation (Tx, Ty, Tz) and three rotation (Rx,Ry,Rz), from an origin O; this origin (O) is defined as a middle point between condyles of jaw. I have a kinematic motion from .txt file in the next configuration: Time Tx Ty Tz Rx Ry Rz
I could drive only one rotation jaw from .txt file with a next configuration Time Rx. I used AnyRevoluteJoint to joint and AnyKinEqInterPolDriver to introduce a kinematic motion. I tried with others joints definitions as AnyUniversalJoint but I couldn’t make.
-What is the correct joint definition in this case?
-How can I introduce a kinematic motion (Time + 6-DOF) from a .txt file?
Thanks you very much

Hi,

  1. If you want to driver 6 DOFs between two segments:
  • define an AnyRefNode on each AnySeg object
  • define an AnyKinLinear and an AnyKinRotational objects
  • define an AnyKinEqInterPolDriver with those AnyKinLinear and AnyKinRotational objects using your text files.

Attached please find an example of AnyKinEqInterPolDriver object.

Best regards,
Moonki
