The people who run the fair will tell you that what the kids building robots are doing actually isn't that different from the kids who are raising livestock. Growth and innovation is really what the fair has always been about.
"The fair has always been about bringing new technology to communities," San Mateo County Fair Technology Department Director Gabriel Colaluca said. "They introduced new tractors and new combines back in the day, and now it's new computers and new digital printers."
The technology exhibits have doubled in size every year, but don't think they'll edge out the animals. Whether it chews through batteries, or chews its cud, there's always a place for it at the fair.
