Bruce Shapiro brought his Egg Bots. This is a colaboration of Bruce, Ben (Bruce's son) and Brian Schmalz. http://www.egg-bot.com/	The Egg Bot.	Another view.	Close up.
These are driver boards that Brian Schmalz designed for the Egg Bot project. http://www.schmalzhaus.com/	Close up of a two channel stepper motor driver.	Close up of a four channel stepper motor driver.	The control software written in Liberty Basic.
When it runs it says these kinds of things.	This guy (I'll add his name later) brought his holonomic drive robots.	Overall view.	It looks like the frame is made of PVC pipe.
There are R/C servos being used as motors.	Close up of the coupling.	You can see that the coupling just joins two big shafts together. I don't know if there is any extra gear reduction between the R/C servo and the shaft.	Some of the people.
Terry Schumacher is working on his robot project.	Terry is explaining his robot project.	I (Jeff Sampson) brought various projects. I think I was promoting quick prototyping.	Jeff Sampson bought (BG Micro?) this VEX radio controll system. It differs from regular R/C systems in that the receiver output is a single line. Instead of 6 decoded channels of a normal system. That makes it easier to interface to a microcontroller.
Some of the people.	Douglas Sasse brought these toy robots.	Close up of the robots.
