You can choose. RoboRealm is designed for Windows, and so needs to run on the dashboard. OpenCV or SimpleCV could theoretically be run on the cRIO, but that would be a lot of work so you'd probably want to run it on the dashboard or a co-processor. NI Vision runs on the cRIO, and there is a tutorial for using it to find the vision targets. http://wpilib.screenstepslive.com/s/...95-c-java-code

2. How do you utilize data from the vision software in the actual robot code?
We write the vision software to determine the distance to the goal and the angle to the goal. We can then use that data to turn towards the goal and drive to the correct distance

3. If the vision software is on the cRIO, do we need a special version of the software compatible with the cRIO and/or will it take up a lot of processing power?
The cRIO is too slow for running high frame rate vision processing, but you may not need to process an image very often.

4. Is it possible to use the axis camera over the network to provide a target tracking system viewable from the driver station during teleop?
Yes. If this is your goal, you probably want to do the vision processing on the driver station.
