Yet Another
Software Suite
Four vendor-agnostic libraries for swerve drives, mechanisms, vision, and mechanism design — built by FRC teams, for FRC teams, with simulation baked in from day one.
The Suite
Each library owns one part of the stack. Use one, use all four — they're built to share a philosophy, not force a dependency.
YAGSL
Yet Another Generic Swerve Library
A plug-and-play swerve drive library. Describe your robot's hardware in a JSON file and YAGSL handles kinematics, odometry, and motor configuration, whether you're wiring up your first swerve chassis or tuning a competition drivetrain.
YAMS
Yet Another Mechanism System
A unified interface for elevators, arms, and pivots, with simulation and telemetry built in from the start. Write your mechanism code once and run it the same way on the real robot and in sim, for FRC and FTC.
YAMG
Yet Another Mechanism Generator
A web-based mechanism simulator and code generator. Prototype an arm, elevator, or turret and see how it behaves before you've cut a single piece of metal.

YAGSL 2026.8.18: A Beta for the SystemCore Transition
A roboRIO-only beta that points YAGSL at the 2027 SystemCore transition. Brushed motor support is gone, gyro support is narrower, and we need teams to try and break it.
