In 2007 we built DEWBOT III to play Rack 'n Roll.
Dewbot III turned out to be a good performer and scorer once we upgraded the gripper for the Philadelphia Regional. Key attributes of Dewbot III include:
- A drive-train and chassis with solid performance and reliability
- An reliable, easy-to-use Arm and Gripper capable of scoring quickly on the bottom two Rack courses
- Ability to climb ramps (for bonus score)
- Robot was logically laid-out and posed no significant maintenance problems
The team suffered from some process problems during build season. Dual Arm designs were pursued to the build season's end. We've learned from this and have subsequently improved our decision-making and Project Management skills and discipline.
What Dewbot III did not have were:
- Ramps or lifts for bonus scoring
- An ability to score (reliably) on the top Rack course
- An autonomous mode
No part of Dewbot III was designed using CAD.

Design Details
- Dewbot III possesses a drive-train and chassis having good performance and reliability. Drive-train is four-wheel-drive (4wd) Tank with Traction Wheels forward and Omni Wheels aft.
- Following some teething problems (which were both technical and process-related in nature), DEWBOT III ended up with a very effective Arm for scoring on the lower and middle levels of the Rack. By gripping the Ringers from the OD, it was easy to pick up Ringers and they were generelly well oriented for scoring. Best of all, the Arm and Gripper did not interfere with the Rack when letting go of the Ringer and disengaging from the Rack.
- An independent regulator let us set the pressure and therefore the closing force of the Gripper. In this way, we gripped Ringers securely, while avoiding collapsing them.
