MikeE,
Your response is the defining start of the compressor rules. Those rules that pertain to off board compressors are not meant to give you an advantage over other teams on the field that do not have an off board compressor. To meet R01 while allowing off board compressors, there needed to be some massaging of the rules. The give and take for off board is reduction in robot weight for a limited air capacity. That is all. Those teams with the compressor on the robot must control it from the Crio and so too should off board compressors. On board uses the robot battery and so should off board. There can be no advantage given in either case. While the current rules do not bring robot battery into the equation, teams with on board compressors can pre-charge their pneumatics and then change batteries prior to taking the field. That being said, the same can hold true for off board. Personally, I would like to see a rule allowing only one battery per match. There are many teams that are on the edge of efficient design that are depleting a battery in a single match. If we are trying to inspire, this is one area we have fallen down on the job.
However, with the variety of pneumatic designs we see, I am always fearful of teams in the queue with pre-charged pneumatics.

Mark,
It's time for a new picture.
