Cost, for the most part. Part of our intent is to have a practice bot to drive. We got the AndyMark ones first and threw them on the practice bot... but we really didn't want to buy two full sets when we have the resources and capability to make our own and save some money. The drive team has been driving the practice bot for over a week now, and can continue to drive it through ship and the three weeks following before our first competition. Granted, the practice bot only has the drive train... but that's enough for practice.
On a side note, thus far this year we've been moving incredibly fast, compared to the last 3. For the "real" robot, the chassis is finished, the wheel mounts are pretty much finished, the kicker is functional, the lifter is in place (although we're still working on the motor mounts), and the electrical system is probably halfway finished. At this same point last year, we were just finishing our prototypes!
