Re: 2011 FisherPrice Motor

I honestly think it is ambiguous if you can use more than one.

Quote:

<R45> Motors specifically permitted on 2011 FRC ROBOTS include:
A. all motors, actuators, and servos listed in the 2011 KOP Checklist,
B. [COTS motors <4W]
C. [CIM Motors]
D. up to four, in any combination, of the BaneBots motors provided in the KOP (RS-775, RS-550, RS-540, RS-395),

Example combinations include, but are not limited to,
- four RS-775s,
- one of each motor
- two RS-775s and two RS-550s,
- three RS-540s and one RS-395.

E. [SPARE PARTS]
F. [fan motors]

I think the wording is interesting. In part D, they use "provided" to mean that 1 motor was included in the KOP, therefore you can buy additional motors of the same type.

In part A, they use the word "listed" instead. To me, this seems as though you can use parts in any quantity as long as they were initially part of the KOP. However, you could argue that this also implies "in the quantity listed," which would really be limiting.

To be honest, the word choice is confusing. The word choice in part D would have seemed more limiting if it weren't for the clarifying box afterwards. I think someone needs to ask the GDC.

Re: 2011 FisherPrice Motor

I'm not convinced that only a single Fisher Price motor may be used. The KOP does list that motor. The KOP also lists the CIM motors. The rules explicitly state you can't have more than four CIM motors. The implication is there that you 'could' have as many CIM motors as you desired were it not for the explicit rule against it. There is no such stipulation for the Fisher Price motor.

It boils down to, "I don't know". It sure would be nice to have that clarified early in the build season.

Which gearbox are you referring to?

If we assume that you're talking about the Fisher Price planetary gearbox AndyMark sells, then you have a 3/8" keyed output shaft. This and the mounting pattern allows you to use the motor just about anywhere you can use a CIM.

AndyMark sells this hub which will let you use that output.

I mean the plastic gearboxes. Like you would find in a Power-Wheels toy.
