FRC Jumpstart

A VS Code extension that generates production-ready WPILib 2026 Java robot code from a curated template library — drops files straight into src/main/java/frc/robot/.

Template families

• Swerve Drive — REV MAXSwerve (SparkMax) or CTRE (TalonFX + CANcoder), NavX or Pigeon 2 gyro, pose estimator with vision fusion.
• Tank Drive — Leader/follower differential drive for REV or CTRE.
• Mecanum Drive — 4-motor mecanum with field-relative cartesian drive.
• Flywheel Shooter — Dual-motor velocity PID shooter.
• Shooter + Hopper — Shooter with beam-break feeder/indexer.
• Turret — Absolute-encoder position PID rotating base.
• Puncher / Kicker — DoubleSolenoid punch with configurable hold time.
• Catapult — Motor windup + home sensor fire cycle.
• Intake (Roller) — Single roller with beam break auto-stop.
• Intake with Deploy Arm — Pivot arm + roller with deploy/stow commands.
• Conveyor / Belt — Belt transport with piece detection.
• Serializer — Two-zone indexer with independent zone control.
• Elevator — REV SparkMax position PID or CTRE MotionMagic (jerk-limited, gravity feedforward) with L1–L4 presets.
• Pivot Arm — REV SparkMax + absolute encoder or CTRE MotionMagic with cosine gravity compensation.
• Double-Jointed Arm — Independent shoulder + elbow position PIDs with combined presets.
• Wrist — Small rotational end-effector with absolute encoder.
• Telescope / Extension — Linear slide position PID.
• Generic Mechanism — Custom name + comma-separated preset positions auto-generates a full subsystem.
• Climb — Dual-motor winch with extend/retract encoder limits.
• Buddy Climb — Deploy arm for alliance partner assist.
• Claw / Gripper — Roller gripper with piece detection and hold mode.
• Pneumatics — REV PH compressor management + DoubleSolenoid template.
• Vision (PhotonVision) — PhotonPoseEstimator with MULTI_TAG_PNP_ON_COPROCESSOR, yaw-PID align command.
• Vision (Limelight) — NetworkTables 4 with botpose, pipeline switching, yaw-PID align command.
• Addressable LEDs — Solid, rainbow, breathe, strobe, chase, progress bar, alliance-aware, indicator.
• PathPlanner Autos — AutoBuilder config, NamedCommands registry, alliance flipping, SendableChooser.
• Choreo Autos — AutoFactory with PID feed-forward correction, multi-segment auto template.

Design

Every line of Java output comes from hand-written TypeScript template literals — no LLM generation. Output is deterministic and verified against 2026 APIs: REVLib com.revrobotics.spark with SparkMaxConfig + configure(ResetMode, PersistMode), CTRE Phoenix 6 TalonFXConfiguration + MotionMagicVoltage, Studica NavX, and current PathPlanner / ChoreoLib patterns.

The panel detects your WPILib project year and language from .wpilib/wpilib_preferences.json and displays it at the bottom.
