I would like to create a new „Application“, where the Hand (including the “Carpals”-Segment) makes a defined motion that is based on measured CT-data from the Carpals.
As a starting point I chose the „FreePostureHandSR” – Application/Model.
To modify the application, I’ve read the Tutorials very carefully and took quite a deep look into the model structure of the “FreePostureHandSR”.
In the following I’d like to ask you a few questions if I got the things right, and if my “plan” might work that way:
To implement this motion I want to drive the “carpals”-segment with CT-measured data-points that I read in from txt-files. To do so there are the following ideas to modify the existing application:
Loose the existing constraints between Radius and “Carpals”-segment, that there is no connection left between the lower arm (containing Radius )and the Hand
Create a new Joint between Radius and Carpals-segment (AnyKinLinear + AnyKinRotational), which Is situated at the very place where the “Capitatum” (bone of distal carpal row) might have its place
Drive this joint by measured data points of the “Capitatum” (translation and rotation)
When doing 3) whole carpals-segment is moving like the Capitatum. Because the carpals-Segment stays linked to the rest of the Hand, whole Hand should move the same way. Reactions from the muscles overdrawing the wrist, going from lower arm to Hand might be possible to measure, too.
When doing 1): did i get this right, that the only jointly constraint that has to be loosened are the ones in “BodyModel/Interface/Right/”, namely WristFlexion and WristAbduction?
Could you perhaps tell me, whether these ideas will work and I got these things right so far?
Thanks a lot!
