Jeff Sampson brought his Research 3 robot. It is green this month.	Craig Smith came all the way from Wisconsin with his R2-D2 robot.	It has this access hatch on the back.	Thre are some controls that use an R/C receiver.
He got an autograph at one of the Star Wars conventions he went to.	The head comes right off. You can see the lazy-susan bearing on the right.	Craig used a phone plug in the center as a slip ring for power.	Another view of the plug and the gear that turns the head.
