Overview

YAMS (Yet Another Mechanism Suite) is a WPILib vendordep library for FRC robots. It provides a unified motor controller abstraction over REV and CTRE hardware, pre-built mechanism classes for common robot subsystems, and advanced control algorithms, all with simulation support and automatic NetworkTables telemetry. Both Java and C++ are supported with parallel APIs.

Features

• Motor controller abstraction: a single SmartMotorController interface over SPARK MAX, SPARK FLEX, TalonFX, and TalonFXS

• Mechanism classes: Arm, Elevator, Pivot, FlyWheel, DoubleJointedArm, DifferentialMechanism, and SwerveDrive

• Advanced control: LQR, exponential motion profiles, trapezoidal profiles, and a derivative-time filter

• Extended units: YUnits constants and EasyCRT multi-encoder absolute position solver

• Simulation: built-in sim support for all mechanism classes via WPILib's simulation framework
