i was watching the Q & A and the GNC was asked how many tanks we can use to hold air. they responded by saying look at update 2. my question is, can someone ask how many tanks since the team update does not specify. and i quote
"<R66> 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 1⁄8” 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).
C. 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.

D. 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,
E. Pressure transducers, pressure gauges, and connecting fittings,
F. Pressure regulators with a maximum bypass pressure of no more than 60psi,
G. 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).
H. 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).
I. 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). J. Pneumatic cylinders. K. Pneumatic storage tanks."
