gear tooth sensors purchasing

[Jared Russell]

From the FIRST manual:

<R28> COTS ITEMS that are generally available may be used on the ROBOT. COTS ITEMS from
ROBOTS entered in previous FIRST competitions or COTS ITEMS that are no longer
commercially available may be used under the following conditions:
° The item must be unmodified, and still in its original condition as delivered from the
VENDOR
° The item must not be a part custom made for the FIRST competition and provided in a
previous FRC Kit Of Parts (e.g. 2006 FRC transmissions, custom-made motor couplers,
custom sensor strips, IFI CMUcam II modules, etc. are not permitted)
° The item must satisfy ALL of the rules associated with materials/parts use for the 2007
FIRST Robotics Competition

Also note that last year's gear-tooth sensors were a different model, and they are no longer available, and therefore not COTS because not all teams can get them.
