And from what i heard about the basic stamp today - DO NOT USE IT EVER
My first robot used a basic stamp; granted it was a BOE-bot, but it worked fine for me. Why would you
not want to use it (has it got worse, since I used it)?
Anyway, if you're looking for something simple and compatible with the $50 robot, try airman00's Roboduino (I've heard very good things about it). Everything's plug-and-play, for the most part; so it can't get much easier than that.
