The CAN bus and the Jaguars are a unique challenge. Many of the problems you'll see can be overcome fairly easily (once you find them)...but not if you're in a hurry. I don't encourage anyone with limits to their patience or available time to try them casually. You'll end up REALLY disliking them if you plan poorly for this and possibly a bit unfairly to them in general.
That being said...I don't advise people to fall asleep in: datasheets, on robots or in the box of the KOP. These would seem to be the places you'll most likely wake up and discover CAN.
Safety first you know.
