Motors for Intake Rollers

[DonRotolo]

Just divide the speed of the motor (in RPM, from the motor data) by the speed you determine with your experiments to be ideal for the rollers (also in RPM - you're doing experiments, right?) and that's the required ratio.

For our prototype we use RS550 motors with a 64 to 1 geardown, and they worked beautifully.

Given the choice between the 540 and 550, I'd go with the 550s.
