Subject: [alt-beam] Re: Whats the direct link?Incredible gear motors


Ok, these motors do sound nice. Yet as I'm sure people have been wondering,
I can't find them at all on the web site. Could someone who knows, please
post the direct link? Or at least some sort of nagavational aid to them. The
lego site is huge, and not too usefull.

Do these specifications sound interesting?

Gear motor:

1cm x 1cm x 1.3cm
2-9v
8mA draw!!! (no load)
32 rpm
surprisingly tourquy
15 grams - VERY light

They could even be smaller, because they are surrounded by a plastic case
that i have not cracked open yet. The source? LEGO. These are the micro
gearmotors for the mindstorms sets. I believe the cost is $17 CAD each. A
friend of mine bought $4000 worth of mindstorms gear and was showing me some
of his creations. When i saw these motors i practically freaked.
Absolutely perfect for heads, and 2DOF heads - because they are so light.
With their low current draw, micro walkers are a possibility. I'm going to
order some and try them out. Never seen gearmotor specs so promising.

You can order them direct from LEGO. www.lego.com

Nowhere near as powerful as a BG mirco, but so much smaller, lighter, and
less draw.

I think a micro walker would be a very interesting project....
