It’s probably too early to say this is really cool, but the pictures they have at White Box Robotics seem to hold a lot of promise. From what I’ve managed to lift, they’re designed with the Via Epia series of motherboards in mind, with Evolution Robotics software running under Windows XP. I have a few work related ideas for the HMV version, if I can talk the boss into it! (Check out this quick blurb on ABCNews.com.)
For those of you looking for something a little more ready-made, check out the RoboSapien. It’s $99.99 from Best Buy, and free shipping!
