DEWBOT IV possessed Team 1640's first (and likely last) 2-wheel drive (2wd) drive-train (the rear wheels are driven). It has a 2-speed transmissions powered by 2 CIM motors each to provide both speed for laps and fine control for catching and placing Trackballs. Driven rear wheels allow us to recover by reversing should we become hung up on the Overpass.
Rear wheels were AndyMark 8" Performance Wheels. 8" Omni wheels were used in the front for agility. Arcade steering (single joystick on the Operator Interface) was employed.
We used
In retrospect, the 2wd drive-train was a poor decision. Inconsistent weighting if the rear drive wheels made DEWBOT IV extraordinarily difficult to drive. Due to some mentor changes, the 2008 drive-train was more of an afterthought than a purposefully designed system. In addition, up to this point, the team had not spent a lot of effort to understand drive-train mechanics.
This clear drive-train performance failure inspired the team initiate drive-train prototype testing during the summer of 2008.
