Is there a way to retrieve the robot and/or controller serial numbers with Karel? Or any other unique identifier of a robot?
I have a few Karel programs that I want to lock to a particular robot and prevent people spreading them on other robots, so I want to add a check for something unique, something that a user cant change through the controller?
I found two system variables 'FNO' and 'PRODUCT_ID' but the values of both of these variables can be changed.
