The rule is specific in the use of servos, and is quoted here:
<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 2½” 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, 2½” 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.
Be prepared with sufficient documentation to verify to the inspector that the servo you are using meets the rule definition. Makes things easier on everyone.
Thanks. Vikesrock answered this 4 days ago and we’ve moved through plan B to plan C that we implemented yesterday. (Turns out a chunk of polycarb was the best solution. Perfect aim, no moving parts, hard to break, easy to make.)
