Problems using neck model
Posted: Thu Nov 26, 2009 4:29 am
I have been trying to use Anita's neck model in OpemSim and I have had a few problems, I've tried a couple workarounds but still amn't getting anywhere. Here's what I've done (sorry if its a bit long-winded)
I imported the SIMM model using the Neck3dof.jnt and NeckMus.msl files. That worked fine.
I then tried to load the motion files associated with this particular model (head3dir.mot , Pitch.mot , Roll.mot , Yaw.mot) but got the following error message for all of them:
Could not read motion file.
I edited head3dir.mot and deleted all the spaces in between the rows and the file then opened. The motion file ran for the correct time span (0 - 100), but the actual motion itself ran far too slowly and only approx 30% of the motion was executed before the time ran out.
I edited the motion file again, this time adding a column titled "time" and inserting values evenly spaced between 0-100 in the appropriate rows. The motion file was now running correctly.
I then tried to perform inverse dynamics. The program ran, but outputted -1.#IND0000000000000000 into every cell in the output file InverseDynamics_force.sto
Seeing as I've hit so many obstacles, I wonder if anybody could help me out?
Thanks
