driving in the y direction

Archive AnyScript Yahoo archive

Hi everyone

I am currently modelling a sit-to-stand in anybody. I have a working
model for gait in the x direction but I need to model the new
sit-stand model in the y (due to the way I captured the motion
analysis). Has anyone tried to run a model driving in the y? I have
changed the Jnt file, the JointsAndDrivers and the Mannequin to fit
the model to drive in the y, but I still have problems running
kinematic analysis.

any suggestions would be greatly apprecaited as always

many thanks

Peter

Hi Peter

I have not tried driving the gait model in the y direction, but if all
marker drivers make use of AnyKinLinear measures based on segment coordinate
systems, it should not matter which direction you are using.

Please verify that all the AnyKinLinear measures have this line included

Ref=0; or alternative Ref=1

When you write ref=0 it will use the first mentioned coordinate system in
the measure, if you are writing ref=1 it will use the second. It should
always be set so that it is measuring using the coordinate system of the
bone, this will make the driver independent of direction.

By default this value is -1 meaning that it will use the global coordinate
system.

If any of the used AnyKinLinear measures are measuring in the global system
it will make a difference which direction it is pointing, otherwise it
should not make any differences.

Best regards

Hi Soren,

I am using Ref=0; in the drivers. I have also tried using the second coordinate
system (Ref=1) with no luck. The area in which kinemaitc analysis is failing is
in the Jnt constraints and Model.Environment.Connections drivers. On
SetInitialConditions I am noticing a movement in the mannequin, I’m not sure why
this is occuring and if it is having an effect on the model running. I am
currently looking in to using Ansys to change the x and y coordinates in the
Points.Markers folder, but ideally I would like to run the model driven in the
y. With sit-to-stand the main movement is coming from the knees and the hips,
with less enphasis in the ankles. Do you think i should change the model set-up
to better represent this?

many thanks

Hi Peter

The movement you see when running the conditions is because the initial
positions of the model do not corresponds 100% with the position of the
first timestep. The initial position is the position the model is loaded in
this is before the kinematic analysis has been done, these positions servers
the purpose of a good starting guess on the position for the kinematic
analysis, nothing more. If the set initial conditions run through the
initial positions are good enough, otherwise they should be improved.

By improving them, I mean that they should be closer to the segment
positions of the first timestep. If you have rotated the model 90 deg, you
will also need to make some changes in the initial positions of the segments
to reflect this. This can be done by making changes in the mannequin.any
file. By changing the pelvislin and pelvisrot values together with the
joints angles you should try to make the free markers and the markers on the
body to be as close as possible when the model loads, before the setinitial
conditions has been done.

So if I have understood you problem correctly I think it is a mater of
providing better starting conditions to the model.

It may also be a good idea to replace some of your maker drivers with joint
drivers, until you have a running model, I would recommend always to
maintain a running model and do the modifications is small steps.

Hi Soren,

The mannequin set up was near perfectly matched with the marker positions in the
first time step, I don’t think this is the problem. The problem lies within the
drivers, when i change the marker drivers to joint drivers the error increases
in the set.initial.positions, so i think its a fundamental problem with either
the marker coordinates or the driver directions. I am sorry to put another model
up, but i feel i have exhausted my efforts in setting up the model. File Trial

Hi Peter,

The problem comes from the marker drivers of the JointsAndDrivers1
file. It is the pelvis that is not correctly driven. You are
actually missing a driver in the Y direction (upward), the linear
combination you made in the Y direction is more driving the rotation
of the pelvis by keeping aligned the 3 points, but not the
translation.
So to have your model working, you must first add a driver to the
pelvis in the Y direction (you can use the AsisLDrv you out
commented and set the MesureOrganizer to 1) and then remove the
driver that drivers the pelvis Y rotation to the ground because the
linear combination measure already drives this rotation.

With these changes the models runs, but there are still some changes
that I would recommend

1 instead of having some the pelvis rotations locked it would be
better to use the marker you have to so that all driver information
is related to the markers.

2 while running the kinematic analysis, a gimbal lock error related
to the ankle joint appears at the half of the analysis. It seems
that the leg is too short to follow the movement of the marker. You
can play around with the scaling parameters of the leg to resolve it
also moving the markers on the body may help.

When creating a model like this, it is normally a good idea to
create a small sketch figure with arrows showing which directions
the markers are driving; it may help visualizing the mechanics of
problem.

I have uploaded a zipped version of the model which contains the
changes mentioned above, the file are locacted in Trial 108
trial108(2).rar. I also changed the path to the bodymodel to be used
directly in file Rep6. You can change it again if you put your model
in a diferent file.

Please in future use a zip archive when uploading models, it is
easier to work with when the model has multiple files.

Best regards,
Sylvain, AnyBody Support
