Our bots have had various lifespans. Our 2001 bot survived in one piece until we scrapped it this year (it had died over the last year, and we needed the space), although half of it still survives. Our 2002 and 2003 bots were scrapped rather quickly. Our 2004 bot is intact with the exception of it's control box and one piston (which was used for our 2005 bot). Our 2005 bot is in the condition it was after IRI (where it got rained on), and is otherwise intact. Our 2006 bot is being repaired for off-season outreach activities, and will likely receive some small modifications for off-season competition.
I think 612 has the most impressive destiny for some of their old bots though
