Re: FRC 2012 Ball Launcher by iR3

I have both a question and an opinion as a response to the question. My question is, do you think it is necessary to use two of the precious four CIM motors to run the launcher? They do have the best balance of speed and torque, but are there any better alternatives out there? I was considering using the AndyMark motors - similar to the size of the FisherPrice motors - because they have very high rpm, but I am not sure about the torque in order to put the ball through with the same velocity as the CIMs would. My team uses mecanum drive, so we are going to use the CIMs for that. I'm just curious if a two wheel drive system will be popular this year because of the necessity for the CIMs on the launcher.

EDIT: I just looked at some motor comparison charts and found that the FisherPrice motors have both higher rpm and torque. I redact my previous statement about the AndyMark motors.
