Stepper Motors

For many manipulators which require small, precise movements, I think a stepper is far easier to use than a DC motor in a closed control loop. Less complexity, fewer failure points.

Please, walk through the selection of a stepper motor and brushed motor for an elevator for this years game. You'll see that you end up with a giant stepper motor (or you'll leave yourself vulnerable to missing counts due to friction/wind blowing/jammed tote/whatever).
