the introductory examples"simulation-based designe to reduce metabolic cost",part4:model building,says:"the opensim software plstform has an extensive library of actuators and controllers",where are they?how can I use them to build a model?
The same as intermediate examples"example-model editing",how can we make the file "bucket.vtp" ,or is there already have such library in OpenSim?
I want to know how many libraries there is in OpenSim , where they are and how to use them.
