DC vs Stepper vs Servo

Three motors. One robot. What to choose?

A spinning motor is essential for our conveyor belt. Without it, Blitz can't get even a single ball. To help us in choosing what motor we should use, we lay down the specs of each one:

DC Motor - Low torque, high speed, continuous motion (forward and backward), already in arsenal
Stepper - Good torque, hackable speed, back-and-forth movement (hard to control)
Servo - High torque, Medium speed, very expensive (360 degrees)

The clock's ticking. We have to decide on this ASAP - before a royal rumble of races begins.
