For those who are interested in the Robotics Environment you've seen at Dorkbot meetings and might want to build a robot (maybe not quite as elaborate as Ward's), I've posted two Instructables you might want to check out. One even has a little video with it! Here are the links:
http://www.instructables.com/id/Cheap-Easy-Robotics-for-the-Non-Programmer/ http://www.instructables.com/id/Simple-Robotics-Breadboard/
The second prominently features the Teensy2 and has a cameo by Dorkboard.
Enjoy!
