Drive System

1. We went with 4" AndyMark Performance Wheels. Custom 2-speed transmission with a real 4.5ft/s low and 17ft/s high. We're using the Poof's amazing chassis (thank you very much 254!).

2. We designed our drive (and a good chunk of the arm) entirely around speed and a low CG (we have about 1/2" - 3/4" clearance). In fact, our driver's gotten good enough that he can take a 100% turn at full speed in high with the arm as high as it can be

1. 8 wheel drive, forgot diameter of our plaction wheels, Andymark Super Shifters for high pushing power low speed gear & high speed gear, and pneumatic cylinders to articulate outside wheels for easy turning or shift gears in the Super Shifters.

2. We wanted to make BOB able to use pushing power while keeping the ability to move across the field quickly if needed at 12ft/s if I remember correctly. The team decided that the middle of the field will be crowded so pushing power will be used if needed to continue on our path or blocking others'.
