I'm still waiting for the brains of this thing to arrive. It's going to be either a Vocore board, with the UNIX version of the Micropython running on top of OpenWRT, and possibly a Pro Mini for the servo controller, or the original PyBoard. The OpenMV project looks like it would be perfect for this, but it's not available yet.

I really hope that I will get it to work with Vocore, because that would mean I have WiFi and USB host -- so a possibility of connecting some laptop webcam module to it.
