I have not heard of this scenario but there is no way that a competition team (Head Ref, FTA, LRI) would allow them to tag team two robots. Most regionals would/should not even allow the second clone into the building. This competition is about one and only one robot built during the current build season. While you can build a second robot and use it for spares, (lot's of teams do this) you can't bring a complete second robot to compete.

Never the less it did indeed happen and I confirmed it with a couple of my former teamates. If my memory serves me right, it was the second year of the GTR regional - 2002? - stack attack. I remember discussing it amongst ourselves and when we asked if they had entered two robots the team confirmed that the second was their practice robot which they brought as a backup. Their intention as was explained was to swap their modular control system if they were to experience a mechanical breakdown and then continue competing with the clone. One of my former team mates recalls them boasting about how they could swap the control system in under a minute.
