Arizona's Reference Build and Software Implementation for FRC robots, read as "A-Z-ribsy".
Az-RBSI is a robot-code template for teams that want a reliable swerve, odometry, vision, autonomous, logging, and tuning baseline without starting from an empty project.

Az-RBSI helps FRC teams with:
- improving autonomous reliability and performance,
- improving robot build, endurance, gameplay reliability, and troubleshooting,
- standardizing a robot stack so teams can set up software quickly,
- making it easier for Arizona teams to form effective in-state alliances.
Az-RBSI is centered around a reference robot that helps teams communicate quickly about gameplay strategy and troubleshooting. A shared robot design also makes it easier to swap spare parts and programming modules.
The software is a robot-program outline that teams can extend for their own mechanisms and game strategy. It combines actively maintained FIRST and community libraries with AdvantageKit logging so teams can diagnose problems from real match data.
