the rules say "<R105> There is no limit to the number of solenoid valves, air cylinders, pressure regulators, and
connecting fittings that may be used on the ROBOT. They must, however, be “off the shelf”
pneumatic devices rated by their manufacturers for pressure of at least 125psi. Besides the
“free” pneumatic components listed on the Pneumatic Components Order form, additional
air cylinders or rotary actuators may be purchased. However, they must be identical to
those listed on the Pneumatic Components Order form (i.e. same part numbers), and
obtained from a Bimba or Parker Hannifan distributor."
