I think the oldest one we have is 2001, not sure how functional it is, but because it is a Champs wining bot we'll probably have it forever. The same goes for 2010. We have another one or two bots in our storage room, one being 2014 with various parts cannibalized, and another robot who's year and functionality I don't know. Our 2015 robot we still have, but in an accident involving a metal pillar the drive base was severely damaged so it's mostly just a donor for parts.. I'm not sure what's happening to 2016, but since it was a good year I assume we'll keep it for a little while at least.
