I have a TAB Sumo-Bot. I do not recomend this product. The drive train is a lot of friction fit thingies that slip... Note the cool appearance though...
Though a poor robot this is an OK Basic Stamp experimenter enviroment.
Chip lineup includes Microchip 16C505, 16C57, and a 24LC16. This is BasicStamp 2 based.
