That depends on the specific implementation of the arduino. We used on last season to turn potentiometer values into floating point numbers. While I was not directly working on the project, I have a friend who was. I would suggest looking up the UnoJoy project. From what he said, the arduino is seen as a PS3 controller with no registering required.

From my brief rereading of the rules, I don't see any issue with incorperating the joystick reading into the dashboard (for instance), sending the information over the network via Network tables/Smart Dashboard, and using those to drive. My only caution is that the field gives driver station status packets priority over other packets, so your driver controls may experience some lag.

If a robot inspector, FTA , or another appropriate authority could clarify, that would be great.
