Rule <R16> states:
Pneumatics. Robots using parts from the VEX IQ Pneumatics Kit (228-8795) must satisfy the following criteria: .... No additional parts that are not included in the VEX IQ Pneumatics Kit (e.g., unofficial tubing or fittings).
However, the kits come with very little tubing which is cut into pieces based on robot needs, and it doesn't appear currently possible to buy more kits or IQ tubing.
Is it possible to use the V5 black tubing or is it potentially possible to revisit this rule similar to the rubber bands to allow outside sources of 4mm tubing?
Additionally the legal parts list doesn't show any of the Pneumatics Kit parts or tubing. I assume they are legal based on the rule book inclusion of them.
