Thanks (and thanks to Bryan who replied off-lugnet) I had forgotten the bit
about those motors being pre-prototypes. When I find time, I'll take a look at
trying to figure out what to do with the more powerful ones. At the very least
if I can get a larger dead zone for the center it will work out okay. I'm
thinking my contribution to the NXT demo at BF may be a RC-Cambot, I'll attach a
camera and make it so the 3rd motor presses the shutter button. I'll be sure to
make it more stable than the ones we had at HoB!
