Kiwi drive in LabView and Java

Any pointers as to where to look?

Maybe there's something in here that would help:

P.S. Our team has never used Kiwi before.

Thanks!
That is the exact page that I used to actually make the LabView VI I attached. It matches the code provided by others here on CD as well.

Thanks Ether, that Inverse Kinematics will be a great help in teaching this process to my students. I guess I had forgotten to search the White Papers for more information on the subject.

Once Spring Break is over, I am hoping to validate my code.
In the mean time, I plan on using my little Vex bot. It works now, but I will be adding a Gyro to it in the next couple of days to help make it even more stable. Currently everything runs in open loop, so you can imagine there might be a few instabilities.

Here is what I have working thus far.
Gyro stabilized for strafing and driving. Rotation is used to set a new heading, then hold that heading once the desired rotation is achieved.

Our kiwi labview source code from 2010 can be downloaded here:

We also uploaded a white paper based on what the labview code is doing. We used a gyro for rotation stabilization as well.

Here is a video of the robot in action:

Thanks Chris!

From the video, it looks like it worked well for you.

The code, though you tool a different approach than we might have, looks quite nice. I'm sure we can learn from it.
