<R74> Compressed air for the pneumatic system on the ROBOT must be provided by the Thomas Industries compressor provided in the 2009 Kit Of Parts. Compressed air shall not come from any other source. The compressor may be mounted on the ROBOT, or it may be left off the ROBOT and used to pre-charge compressed air in the storage tanks prior to bringing the ROBOT onto the playing field. Off-board compressors must be controlled and powered by the ROBOT.
• Note: The only difference between an on- and off-board compressor is that the off-board compressor is physically removed from the ROBOT. The intent of this rule is to permit teams to take advantage of the weight savings associated with keeping the compressor offboard. However, using the compressor off-board of the ROBOT does NOT permit noncompliance with any other applicable rules.

Emphasis mine.

The offboard compressor must be run from the robot which means that the robot must have the electronics to properly run it installed which includes a Spike relay and properly installed pressure switch.
