We have a subteam working each subsystem. This usually means that we build one instance, and then the other. We don't decide until within a few days of bag which one will be the competition robot and which will be the practice robot.

Our drive chassis the past two years have been mods to the AM14U2, which makes it easier to keep them identical, and provides lots of standard mount points for the manipulators.

For Recycle Rush, we changed our mind as to which robot would be bagged within 24 hours of bag as the second robot finally came together.

For Stronghold, we had two identical drive chassis (including controls and pneumatic infrastructure), two identical launchers (although one of them has not been final-assembled as our pneumatic cylinders did not come in until after bagging), and several pickups (five) that were each improvements on the preceding design. The first four iterations became better at pickup and delivery to the launcher, the final is not quite as effective at pickup as the preceding model, but is significantly more robust.
