My aim is to run the BikeModel, from the repository, with insert
measure-dates. If I understood the tutorial correct, then I should be
able to this with the driver AnyKinEqInterPolDriver. I used the
tutorial DemoForces.any as model-example.

First I tried to apply the driver AnyKinEqInterPolDriver by the file
Demo.SliderCrank3D.any. I tried to force the slider for- and backward
(like the dummy in DemoForces.any), but I did not work!

I have two problems:

With the driver I can move the slider only when I delete the two
other segments.

If I apply the same orders (from 1.) to the whole SliderCrank, it
does not work. I got the error message : The matrix must contain the
same number of rows as there are coordinates to be driven. Model
loading skipped.

My questions:

Do you know what I did wrong?

Do you have an example, where you are using AnyKinEqInterPolDriver
for moving a segment?

How could I insert x,y,z coordinates (Data) per time (T)?

Thanks for using the Yahoogroup. Here are some short answers:

My best guess is that you added the interpolation driver to the
slider but forgot to remove the simple driver from the revolute
joint. In general, if you add one driver you have to remove another
one. Otherwise the system becomes over-determinate.

I shall upload a simple 2-D gait example to the files section of
the group. This example uses motion capture data to drive the gait
cycle.

I think the best would be to have a look at the files enclosed in
the gait example. It should be self explanatory. If not, please ask
again.

Best regards,
