Modification of Joint Driving File

Archive AnyScript Yahoo archive

Hi Søren:

I have a small question regarding the drivers of a joint.

I drive a joint using the data from experiment, e.g.,

AnyFolder Drivers = {
AnyKinEqInterPolDriver MCPMotion = {
AnyUniversalJoint &Jnts = Main.Model.Jnts.MCP;
FileName = “MCP_data.txt”;
Type = Bspline;
BsplineOrder = 4;
Reaction.Type = {Off,Off};
}; // MCP driver

MCP is a universal joint, with 2 DOFs; the “MCP_data.txt” is in a
form of “time, angle (rad), angle (rad)”. The model works OK.

My question: Is it possible to modify the anyscript code to vary the
drivers, without editing the driving file “MCP_data.txt”? For
example, I need to vary sign (-/+), change from deg to rad, or
magnify the variations in certain DOF, etc.

Thanks,

John Wu

Hi John

Yes this is possible :wink:

It can be done by reading in the data into an interpolation function and
then use its data in the driver function. When you refer to the data you
have the chance to change the sign etc…

So it would look something like this:

AnyFunInterpol datafun =

{

 FileName = "MCP_data.txt";

Type = Bspline;
BsplineOrder = 4;

};

AnyFolder Drivers = {
AnyKinEqInterPolDriver MCPMotion = {
AnyUniversalJoint &Jnts = Main.Model.Jnts.MCP;
Data=-1234565767*.datafun.Data; //here you can change the raw data…

T=.datafun.T;

Type = Bspline;
BsplineOrder = 4;
Reaction.Type = {Off,Off};
}; // MCP driver

Hope it was something like this you were looking for.

Best regards

Hi John

One more comment on this topic…

It is of course also possible to use the AnyInputFile instead of the
interpolation function when you read in the data, this would be more elegant
solution.

The solution would look almost the same only the “datafun” changes…

AnyInputfile datafun = {

FileName = “MCP_data.txt”;

};

Søren:

Thanks for the response and clever solution. There is a problem.

By specifying:

…
Data=-1234565767*.datafun.Data;
T=.datafun.T;
…

you will manipulate both DOFs of “datafun.Data” in the same manner.
How to modify each DOF individually? Can I do something like:

…
AnyVar a=-1.0;
AnyVar b=2.0;
Data={a*.datafun.Data[0],b*.datafun.Data[1]};
T=.datafun.T;
…

However, “AnyInputFile” does not work. The data could not be read in.
I don’t know the reason.

Hi John

It sounds good that you found the way to modify the individual dof’s.

I have tested a small script making use of the input file solution and it
works ok for me, so I think in your case it must be related to the specific
input file you have.

Is there anything special about it?

If possible you could upload it and we could try debugging on it, we are
always interested in models that can reproduce problems, this helps us
removing them.

For now I think you should change the interpolation function type to
piecewise linear in this way you can avoid having double interpolation added
to your data.

Best regards

Søren:

You are right. There is problem with my data format. I read the data
and output in the format of MS-DOS-txt file in Excel,
and “AnyInputFile” works fine now.

Thanks, John
