That rule states there is no limit to the number of pneumatic devices, so long as they are commercially avalible and rated for at least 125psi. This would include rodless cylinders, rotary actuators, pneumatic grippers, multiposition cylinders, and countless solenoid valves, for these are all avalible from any number of different manufacturers. I don't see how that seems restricted.
This is mostly correct. <R54> also limits where you can get the solenoid valves and air cylinders thus eliminating the majority of actuators on the market. The Flowchart is very strict, the answer is NO for just about any pneumatic device. Unfortunately the air filter you used was also not allowed as it is not a connector or an approved device. It is a great idea and something that is installed on all equipment in my plant.

Pneumatics, and electrical, have been the most tightly controlled areas of the robot. The reason is safety. Many teams have members with experience in these areas. But think of the rookie team consisting of one science teacher and students who never worked with air before. The rules are their roadmap to prevent accidents.
