Rob:

I am using 2 "Tracked Vehicle Chasis" from TAMIYA (http://www.tamiya.com/).
as the mobile platform. I found a better hackable one at www.robotstore.com

3-354 - Bulldozer Kit - $37.95

Or you can buy just the motor:

3-709 - Twin Motor Gear Box Kit - $19.95

The tread on the kit I am using can be made small or large (connect
together).
This way I could make the kit very small, depending on what I want. I hope
this helps.

Best regards,
Steve
