ended up in a discussion of what the voltage/current limitations (and lifetimes)
of the various battery boxes are. Yes, I realize 6 AA's pack more power than one
standard 9v battery, but what is the maximum current draw from 6 AA's vs 1 9v?


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


PS - watching 8 lbs of Lego smash together at a relative speed of better than 1
ft/sec can be an interesting experience...


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.

(...) Or (from the standpoint of sumo) provide enough current so that the RC motor is not current-limited by a measly 9v battery. There's the related question of the total power (amp-hours, or similar units) in each of these different battery types, (...) (20 years ago, 3-May-04, to lugnet.robotics)

Philippe has done an outstanding job on his motor comparison page: (URL) now I find yet another (apparently) unanswered question. Recently at a sumo event my robot was, um, how shall I put this... "exposed" to a monster running multiple 5292 motors (...) (20 years ago, 3-May-04, to lugnet.robotics)
