'ServerBot'

I was inspired (and pretty amazed) at the ServerBot instructable that someone had made for the iRobot Create challenge (LINK). So inspired, in fact, that I would like to try to make one. The problem is, I have a low budget, only knowledge in Basic Stamp 2, and I have some, but not many, types of sensors. I am almost sure this is possible (even remotely, at least) with the basic stamp 2. I have some of the ideas for the coding in my head, and some idea of how to make it. If I do follow through with this, I will make an instructable on it. But I need some ideas. Is this truly possible with a basic stamp 2? Elaborate, please!
