We use our '06 robot for presentation and display purposes. Most of the others have either been modified for prototyping or just gradually gutted over the long process of time. Some, however, still work, and we utilize them for driver practice and game simulations from time to time. Best use of old robots, though, in my mind, is to show visitors and potential members the variety that this program has shown, and helping both relate team history to new members and show them just what they're getting into(and how awesome FIRST really is
)
