The real question is this: How many 9v boxes must you connect in parallel to
provide the same "power" as 6 AAs?

Rough calculations show ONE of those robots could go over 2.5 ft/second, so the
closing speed was 3 ft/sec, or more...
My favorite part of the day was watching that piece fly off a robot and over
John's head, when he was standing several feet from the ring.
The saddest part was when that 1/2 bushing fell off Aaron's robot and slowly
rolled all the way across the ring, and onto the floor, just before he could
push his opponent off.
