Here is the full text of the rules quoted above:

<R59> Additional motors specifically permitted on 2008 FRC ROBOTS include:
• All motors, actuators, and servos provided in the 2008 Kit Of Parts,
• HITEC HS-322HD servos,
• FIRST Tech Challenge (FTC) servos (Innovation First part number 276-2162),
• FIRST Tech Challenge (FTC) motors (Innovation First part number 276-2163),
• One or two additional 2-1/2” CIM motors (part #FR801-001 and/or M4-R0062-12 in addition to those provided in the Kit Of Parts. This means that up to four, and no more, 2-1/2” CIM motors can be used on the ROBOT.

<R60> Items specifically PROHIBITED from use on the ROBOT include:
• Electric motors and/or servos different from, or in addition to, those in the Kit Of Parts, with the exception of those specifically permitted by Rule <R59>.
• Electric solenoid actuators (note: electric solenoid actuators are NOT the same as pneumatic solenoid valves – the latter are permitted, the former are not).

That is it for electric motors, servos, solenoids...
That leaves you to consider pneumatic devices which are also restricted to specific devices in the rules.
