Sitting at the table next to mine at the show was Steve Gostelow who brought one of his robotic friends with him. Any sci-fi fan would know this robot as a Dalek, the most powerful and evil villain of the long running British sci-fi series "Dr. Who". Those of us who did not learn to fear Daleks as a small child would recognize the fact that it is easy to avoid a robot that can't climb up a flight of stairs.
