wrt54g as robot brain
Andrey Mikhalchuk demonstrates how to hack a popular wifi router to have an rs232 interface (or two). The openwrt project allows us to actually use that powerful hack. Andrey did what few people did before: he added a micro servo controller and TING robot's done!
I always had the desire (and a legitimate business need) to operate anything wirelessly via tcp/ip. Linux is my specialty. This seems the way to go. These routers can be had for little money at second hand market places.
Adding wireless communications to a microcontroller can be very complex or very expensive. This is doing the reverse: adding a uC to a preexisting wifi router. The accompanying powerful processor/memory makes your dream platform complete.

I had just built an interface very similar to yours.
I built the interface in the case of a dead router.
The ribbon cabel connects the two boxes together on the front and I used RJ connectors on the back for ttyS0 and S1.
The only parts I had to buy was the max3232 chip and the piece of cicuit board. Everything else I was able scrounge of of old computer boards. The trouble is now that I have it built I dont know what to do with it.

When you make this as a robot with web interface and a wireless pan and tilting camera, you better make a tutorial :P
Oh and you should use a Picaxe 28x1 or something other than the Servo Controller they used
