Pneumatics R88 Question, Parker-Hannifin cylinders

[FRC304]

Are we allowed to use Parker-Hannifin pneumatic cylinders from previous years (as long at they are physically identical to those available on the Custom Cylinder Order Form)? Bimba part numbers are quite different from Parker-Hannifin part numbers (even for identical cylinders).

[QUOTE]<R89> In addition to the pneumatic cylinders provided in the Kit Of Parts and the “free” pneumatic cylinders available for order through the Free Pneumatic Components Order Form,
additional air cylinders or rotary actuators may be used. All cylinders, regardless of source,must be identical to those listed on the Free Pneumatic Components Order Form (e.g. same part numbers). Any additional air cylinders must source from Bimba or Parker Hannifin, or be recovered from prior year FIRST Kit Of Parts.

<R90> Items specifically PROHIBITED from use on the ROBOT include:
 Any air compressor other than, or in addition to, the one provided in the Kit Of Parts.
 Pneumatic cylinders and actuators different from those in the Kit or found on the Free
Pneumatic Components Order form, with the exception of those specifically permitted by
Rule <R89>.

(emphasis added)

[GDC]

Under the conditions of Rule <R89>, certain Parker Hannifin cylinders are permitted on 2008 FRC robots if:
• they have been recovered from prior-year Kits Of Parts, and
• they are one of the permitted sizes (i.e. same bore and stroke as those identified on the 2008 Free Pneumatic Components Order Form), and
• they are physically identical (i.e. same stroke, diameter, mounting method, external dimensions, port configuration, and material) to one of the permitted Bimba cylinders.
