Keep in mind that the rule does not specifically say that you can practice before the regional, it says you can scout, etc.

That said, personally, when it comes to the law and to these robotics rules, anything that isn't specifically banned is legal, and in this case, practicing with the robot is not modifying it at all, especially since it is not the bot that is even entered in the competition. The purpose of R14 is simply to stop people from adding on to their robot in the many hours that they have at each regionals.
