RigidTendonMuscle

Post by Dustin Crouch » Wed Jan 04, 2012 12:18 pm

What muscle model (Thelen2003, Schutte1993, etc.) does the RigidTendonMuscle actuator use? I read in the .h file that force production is instantaneous, with no excitation-activation dynamics - is this correct?

Hi Dustin,

Here's the documentation from Doxygen
A class implementing a RigidTendonMuscle actuator with no states.

The path information for a RigidTendonMuscle is contained in the base class, and the force-generating behavior is defined in this class. The force (muscle tension) assumes rigid tendon so that fiber-length and velocity are kinematics dependent and the force-length force-velocity relationships are evaluated directly. The control of this mode is its activation. Force production is instantaneous with no excitation-to-activation dynamics.
Hope this helps,
-Ayman
