So comparable to a Fischer Price, but much more powerful, Unfortunately my entire robot platform was thrown out in a fit of spring cleaning - the gears cost about 300 bucks for two sets.

I had some pictures, put heck if I can find them.

SO worm gears will work, and you can make the transmissions with just a good drill press if you are carefull and precise.

I got the gears from "Boston Gear"

Boston gear also produces stock worm drive gear boxes, they're really efficient for worm drives and are quite heavy duty. we used one in our drive train last year and it worked beautiful. Picture Here. I beleive these were a 20 to 1 reduction and these had no backdrive.
