Well, those motors on my caterpillar bot aren't as efficient as i thought. =
So i tried hooking up a larger battery (6volt lantern battery, yikes!) and =
off it went. I was really surprised how the motor turned continuously like =
that. Anyway, with some larger batteries i'll be ready well under 2 weeeks.=
Any one have any suggestions for batteries? I started by using extra heavy=
duty ni-cads (2) but that don't seem to be working.

Thanks!

The 'bot's been done for over 2 weeks, its the videos that are not quite
ready.

Depending on how they are encoded, the videos can really trash the
movement
of this sort of BEAM creature, making it look much less fluid and smooth
than it
actually is.

The video tape is being re-digitized and encoded to fix this as much as
is possible,
but even seeing the analog output from the cam-corder its clear that
something has
already been lost in the recording process.

But as long as I dont drop any if the NTSC frames (fields actually) it
should do well
enough.
