This will allow you to run your jaguar motor controllers on arduino over the can bus. There are 3 features that aren't supported yet and that is getting speed, position, and limit switch status from the controller. I had an issue with the jaguar sometimes sending a number that confused the arduino, so I will release that when I figure out what is going on.
I started working on this library probably a good 8 months ago. Then I didn't work on it for quite some time. Its spring break now and I decided I better finish it. So here ya go

Next I'm going to release the entire ArduRIO control system
