Hi my name is William, I’m an undergrad at MSU and have been
learning the software the last few weeks,
My current objective right now is to model a right arm using motion
tracker data i have gathered, doing a very simple motion.
I tried using an arm alone but could not resolve all of the loose
variables, so I am using the standing model, from the repository.
I followed suite with the handle tutorial and removed the 3
constraints in the arm, and all of the wheel components, and
inserted a driver for just one node in the hand. The file compiles
and I am sure I have the right number of constraints, but I am
encountering several kinematic errors, the small ones are on various
parts of the body but the major refer to my driver which is moving
the node with measurements which doesn’t make sense, I am going to
upload the folder with all my files I will call it ArmModel. My
driver is in the the Environment.any file, if any of you could take
a look and see if my approach is on the right track I would
appreciate it, I want to use 5 pts, but am starting by just trying
to use 1 pt as of right now.
First of all welcome to the group. I am not sure I understand what you
followed? If you wanna make an arm movement I thing you will need more
than just one node. The shoulder is a spherical joint so there is a
rotation you have to take care of in some kind of way, I don’t know
how you do it, but if you are sure you have your constraints worked
out, then fine by me;-)
Anyway I looked a bit on your model. The error you are having could be
caused of the fact that there is a long way from your “initial
position” to the position you want the arm in. The initial position
can be set in the mannequin.any file were you set the joint angles.
You should put your driver code in the file called JointsAndDrivers.any.
Hopefully I helped a little bit, else upload you model again and we
can “talk” more about it:D
It would be easier if you zipped the files, then I don’t need to
download each single file;-)
Have fun modeling:D
Best regards
