I think you do NOT have enough muscles in your setup, at the moment you have only muscles in there to bend the arm.
PLease look at the Tutorial: Getting started with ANyScript: Lesson5: Definition of muscles and external forces and see what muscles are necessary…
There is no example of a mocap(c3d) driven arm alone. You need to use the spine in order to get the muscles for using the arm. You can start with either using the GaitFullBody or maybe better, with the WheelchairRancho example.You have to take out the markers that will not be used, change the names of the remaining markers, and insert drivers instead.
Previously, I tried out GaitFullBody.
But my c3d data did not work because there was no force plate data and analog data.
WheelchairRancho, I hope it is successful.
Shoulder joint, I changed to AnySphericalJoint from AnyRevoluteJoint.
I get an error in InverceDynamics.
ERROR(OBJ.MCH.MUS4) : C:/Users/MoCap/D…s/An…y/forum/20120127_2.any : ArmStudy.InverseDynamics : Muscle recruitment solver : maximum number of setbacks occured
I don’t know the meaning of this error.
and how to resolve.
I think it is the same problem again, you don’t have enough muscles in the setup.
Going form a revolute joint to a spherical leads to more DOF and more possible motions. However, you will need muscles that are capable of creating this motion.
Thanks for reply.
I attached the muscles in the axial direction Z.
As a result, I now can inverceDynamics!
I hope that this approach can be parsed correctly.
