Our chasis is almost complete, the drive train and the wheels still need to be mounted. I spent this whole weekend and got the eletrical board completely finished. Last year they were waiting on the eletrical board, so its a nice change of things- I can bug them to finish.
The OI is also finished. We've got a design down for the way we want to move the trackball around, we just have to make it. Lots of programming needs to be done but that usually doesn't take to long. I'd say we're definately ahead of schedule.
