Quadrangles Robotics

Robots Large and Small

Watch our experienced drivers maneuver robots to complete tasks—then you give it a try! Our student team members answer your questions about robots and help you learn to drive them.

We’re Quadrangles, high school FIRST Robotics Team 3494 in Bloomington. Each year we compete in district, state, and world robotics tournaments.
