spiffyspleen - That's not what they mean. Available from FIRST Choice this year is a "pneumatic muscle" - see page 9 here:

In addition to the items included in the KOP, pneumatic system items specifically permitted on 2011 FRC ROBOTS include the following items. All included items must be “off the shelf” COTS pneumatic devices rated by their manufacturers for working pressure of at least 125psi and burst pressure of 250psi, and used in their original, unaltered condition (except as required for assembly with other components).
A. Pneumatic pressure vent plug valves functionally equivalent to those provided in the KOP,
B. Solenoid valves with a maximum ⅛” NPT port diameter, and a maximum Cv of 0.32 (if non-KOP valves are used, the team will be required to provide part documentation validating that the valves meet these constraints).
Solenoid valves that are rated for a maximum working pressure that is less than 125psi rating mandated above are permitted, however if employed, an additional pressure relief valve must be added to the low pressure side of the main regulator. The additional relief valve must be set to a lower pressure than the maximum pressure rating for the solenoid valve.
C. Additional 0.160” inside diameter pneumatic tubing functionally equivalent to that provided in the KOP, with the pressure rating clearly factory-printed on the exterior of the tubing,
D. Pressure transducers, pressure gauges, and connecting fittings,
E. Pressure regulators with a maximum bypass pressure of no more than 60psi,
F. For the purposes of the FRC, a device that creates a vacuum is not considered to be a pneumatic device and are not subject to the pneumatic rules (although they must still satisfy all other appropriate rules). These include, but are not limited to, venturi-type vacuum generators and off-the-shelf vacuum devices (as long as they are powered by provided or permitted motors).
G. For the purposes of the FRC, closed-loop COTS pneumatic (gas) shocks are not considered pneumatic devices, and are not subject to the pneumatic rules (although they must still satisfy all other appropriate rules).
H. For the purposes of the FRC, air-filled (pneumatic) wheels are not considered pneumatic devices, and are not subject to the pneumatic rules (although they must still satisfy all other appropriate rules)

As near as I can tell, the pneumatic muscle available from FIRST Choice is not specifically listed here. So, this begs the question... are items from FIRST Choice considered to be part of the KoP, or simply COTS items? I know there's a thread around here somewhere discussing that very question (mostly for the purposes of cost accounting), but can't seem to find it at the moment.
From Bill's Blog,
http://frcdirector.blogspot.com/2010...st-choice.html, you would expect FIRST Choice to be considered part of the kit, as he states:

FIRST Choice is an online extension of the traditional KoP where teams can pick and choose the items they would like to add to their kits.

But from the game manual, the kit is defined as:
And the parts from FIRST Choice are not listed in the checklist. This likely needs some clarification from the GDC before anyone really knows what to do with those items from FIRST Choice...
I don't think we really fit into those rigidly defined categories, my team builds our robot. - AdamHeard [more]

It's always a tradeoff... I wish you luck!
