We will probably put this on the FIRST Q&A, but for now we'll ask on Chief Delphi.
We are experimenting with a ball control mechanism that uses small, store-bought shop vacs to suck in and hold a ball.
The thing is, they have motors inside them that run the vacuum. These are of course not from the KoP. Are these vacuums still legal since they're COTS? It doesn't seem so...
Thanks!

<R30> Robots entered into the 2010 FRC shall be fabricated and/or assembled from COMPONENTS, MECHANISMS and COTS items that are constructed from:
A. Items provided in the KOP (or their exact REPLACEMENT PART)
B. Additional parts and materials as permitted in these Rules, in quantities consistent with the Budget Constraint rules (found in Section 8.3.3). The use of non-KOP items or materials shall not violate any other robot design or fabrication rule.
<R52> Motors specifically permitted on 2010 FRC ROBOTS include:
A. All motors, actuators, and servos listed in the 2010 KOP,
B. An unlimited number of COTS servos with a maximum output torque of 55 oz-in and maximum rotational speed of 100 rpm at 6 Vdc (e.g. HITEC model HS-322HD or HS-325HB servos, as provided in the KOP),
C. An unlimited number of FIRST Tech Challenge (FTC) servos (HITEC HS-475HB servos),
D. One, two, or three additional 2˝” CIM motors (part #FR801-001 and/or M4-R0062-12) in addition to those provided in the KOP. This means that up to five, and no more, 2˝” CIM motors can be used on the ROBOT.
E. Identical one-to-one SPARE PARTS for motors, actuators, and servos provided in the 2010 KOP that may have failed or become damaged.
<R53> Items specifically PROHIBITED from use on the ROBOT include:
A. Electric motors and/or servos different from, or in addition to, those in the KOP, with the exception of those specifically permitted by Rule <R52>.
B. Electric solenoid actuators (note: electric solenoid actuators are NOT the same as pneumatic solenoid valves – the latter are permitted, the former are not).

EDIT:
One of our team members remembered this rule, which clearly allows off-the-shelf vacuums with provided motors.
Quote:
<R72> In addition to the items included in the KOP, pneumatic system items specifically permitted on 2010 FRC ROBOTS include the following items. All included items must be “off the shelf” pneumatic devices rated by their manufacturers for pressure of at least 125psi, and used in their original, unaltered condition (except as required for assembly with other components).
H. For the purposes of the FIRST competition, 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).
