Cuddles was built to play Logo Motion and had several design achievements mind: maneuverability, high scoring capability, and reliable minibot deployment. The team quickly identified that one of the hardest things in a match would be driving, so mecanum wheels were chosen to give our driver highest level of maneuverability. Another design challenge that the team overcame was deciding upon which motor would lift our arm. The team settled on two window motors because when the arm was fully lifted, the robot would not have to constantly feed power to the motors to keep it up. Instead, the worm gear within the window motors would keep the arm locked in place.
During the lunch period of the Saturday of week 5, students gathered in Mr. Coupland’s classroom to decide upon a name for the 2011 robot. Students took their time to suggest names to captain Jeffrey H. After a bulk of suggestions were suggested, each name was reviewed by the entire team with a vocal confirmation. If a majority of students said a yes, the name would continue to round two; if the name was largely disliked, it was removed from the suggestions board. Only 4 names made it to round two, and the each team member had one vote. Students and mentors voted upon the name that they most liked.
The robot had a claw that largely resembled a eagle claw. One student thought that due to the resemblance to the eagle, the robot was hug-able and cuddly, thus arriving to the name suggestion of Cuddles. With a great majority of the team on board with naming the robot Cuddles, the 2011 robot’s official name was therefore Cuddles.
