Redundancy. I seem to recall that at one point in 2005, a PWM for an arm motor's controller somehow disconnected on 330's robot. We didn't notice for I don't know how long, simply because the other motor on the arm was enough. In 2007, with the same design, we removed one arm motor to make weight with both ramps.
