2016 – Qbot

Naming Qbot

Qbot was named long before it was built. Following the tradition of naming the robot after our former mentors allowed us to pick a name before the season started. It also honors our leaders and teachers, Qbot was named after Quentin Weir.

Game

FIRST STRONGHOLDSM is played by two alliances of three teams each. Alliances compete against each other to breach their opponents’ defenses, known as outer works, and capture their tower. They score points by crossing elements of their opponents’ outer works, scoring boulders in their opponents’ tower goals, and surrounding and scaling their opponents’ tower itself.

Design

At first (no pun intended) we thought a robot capable of shooting the defenses was more important that one that could cross the low bar, the permanent element of the outer works. As it turns out it was possible to build one robot that could do both, which we succeeded in doing.
