R01 specifies ONE robot. So, if you have a practice robot, don't bring it with you to competition.

However, if you also happen to be using the practice robot as a place for spare parts to be tested (and who wouldn't raid a practice robot to have spares for the competition robot?), you can have up to 30 lbs of fabricated items and unlimited COTS items, which may or may not have been tested on the practice robot at your option.
