Well, HEAD motors shouldn't be really fast. The gear ratio should be between
30 to 1 and 200 to 1.

I think that the 'bot is the same one, but the one in the first section had
been modified and then filmed again as the second section.

I think it is a good motor.

http://www.resunltd4u.com
They also have a type A portescap that turns 68 rpm, i don't think it's
listed on there site though.

Yes, but it might be easier and better to use the Almost complete walker
schematic on his website, its on the bottom of that schematics page. I've
used it for my walker and it is quite nice, even has a reverser circuit built
in, thats a pretty easy freeform, if you careful, otherwise, just take a look
at the bicore circuit and add a second on the same chip, you can have up to
four.

Maybe, you need to look at the kindof current drawn by these motors. Some
motors suck up well over 50 some mA, depends on the motors though. even so,
its pretty simple to use a motor drive, it just hooks right into the spot for
motors
