Looking through the Lego Shop-At-Home catalog (1-800-453-4652), it looks
like the best deal for a starter robotics kit would be the Universal Set
with Storage Case (#8062) for $68. Not that you would need the case,
but it has a bunch of general purpose pieces, an assortment of gears and
pulleys, and six medium-sized wheels. The second-best would be the
Giant Model Set (#8277) for $44. It has the very useful longer beams,
but it has smaller wheels and few gears. The Gears & Differentials
assortment (#5229) can be added for $4.50. BTW, the Mini Motor (#5225)
for $17.50 is a compact, efficient gear motor that runs well directly
off the HB. Shipping is free. (Note: I don't get any kind of kickback
from Lego--I'm just a big fan).
> Also, how do you interface a random DC motor with the LEGO gears? Can I just take one small gear and glue/epoxy it in place on the motor output? Is there another trick I should know about? (Sorry for the stupid questions, but I've never played/used LEGO before, unless you count playing DUPLO with the kids...)
The Lego gears are designed to press-fit onto the plastic Lego shafts,
which have a "+" cross-section. To fit 'em to a round shaft, try gluing
a short section of shaft into the gear first (with epoxy?), then
drilling the appropriate size hole through the shaft. If you glue a
Lego bushing onto the assembly before drilling, you might be able to
drill and tap a hole for a tiny set screw, too.
> What set are you using?
I'm using a bunch of sets that I've been collecting for years. The big
one was the pneumatic claw rig for about $120, but I don't think they
sell it anymore. It came with a motorized air compressor for the
pneumatics! No matter how many sets I have, I still drool over the
catalogs. If I didn't already have the HB, I would save up my meager
research assistant stipend to buy the Lego Mindstorms kit.
Hope this helps. Good luck!
