We don't keep most of our robots. Most of the parts are recycled for the next year...
But one of the few ones that have stayed ever since was our very first robot, Bob. He's in our Awards Room, so we haven't operated the robot in YEARS. I'm sure it's still working though, underneath all the collected dust.
If you don't know of the story, the Fembots built Bob at Silicon Valley Regional back in 2001. The Fembots arrived with materials and the Kit of Parts and were able to build the robot with the help of several other teams -- and they built it in 6 hours!
