Motor Limit
 

Specifically, what is the total number of motors that we can use in our robot? Can I use all the motors that came with our Kit of Parts?

Re: Motor Limit
 

<R45> Motors specifically permitted on 2011 FRC ROBOTS include:
A. all motors, actuators, and servos listed in the 2011 KOP Checklist,
B. an unlimited number of COTS servos with a maximum power rating of 4W ,
© FIRST 2011 FRC Game Manual, Section 3 – The Robot, Rev H Page 21 of 35
C. one or two additional 2½” CIM motors (part #FR801-001, M4-R0062-12, AM802-001A, or PMR25R-45F-1003) in addition to those provided in the KOP. This means that up to four, and no more, 2½” CIM motors can be used on the ROBOT,
D. up to four, in any combination, of the BaneBots motors provided in the KOP (acceptable part numbers are M7-RS775-12, M7-RS775-18, M5-RS550-12, M5-RS550-12-B, M5-RS540-12, and M3-RS395-12),
E. identical one-to-one SPARE PARTS for motors, actuators, and servos provided in the 2011 KOP that may have failed or become damaged,
F. drive motors or fans that are part of a speed controller or COTS computing device.

This should help you, along with R<46>
Given that you can only use 4 CIMs, 2 right Windows, 2 Left windows, 4 BB and 1 FP, that gives a grand total of 13 motors.
