Qbot was originally named long before it was built. Following the tradition of naming the robot after our top mentors allowed to pick a name before the season started. It also, you know, honors our leaders and teachers, as a good side effect. Qbot in particular was named after Quentin Weir.
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.

At first (no pun intended) we thought a robot capable of shooting the defences 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 to do both, which we succeeded in doing.
