October 2025 performance summary for FRC7902 Offseason-Reefscape2025-Team-Fire. Delivered critical operator input updates to Xbox with coral handoff improvements, enabling direct coral pass-through during handoff. Overhauled elevator/arm control with new setpoints, max heights, mass, ramp rate adjustments, and smart dashboard integration, accompanied by safety checks (isFinished) and visibility enhancements (get arm enum on dashboard). Implemented auto-align enhancements and stability fixes, including loop control refinements, removal of auto-align timeout, and direction/coral-beam logic fixes, plus refactors for maintainability. Rolled out dashboard UI improvements to surface autoalign errors and improve operator visibility; added basic Todo functionality and started documentation and formatting improvements for team collaboration. Cleaned up codebase with linting fixes, unused imports removal, and refactors, improving reliability and maintainability. Aligned work to business value: reduced handoff latency, improved automation reliability, and clearer monitoring/alerts for faster problem diagnosis.

September 2025 performance summary across three repositories: FRC7902/Offseason-Reefscape2025-Team-Fire, FRC7902/Reefscape2025, and MES-Website-App-Router. Key features delivered: - Coral Beam Corrections and Coral Beam Break Handling: improved coral positioning just above the deep beam break and re-enabled coral beam break for stability. - End Effector Command Refactor: refactor commands to end effector commands package, introduce hold effector command, and rename commands; fixes to wiring and naming for maintainability. - Auto Intake System: working auto intake command and elevator enum usage fix to stabilize auto intake flow. - Swerve and Joystick Input Handling: added strafe commands and dynamic joystick input scaling inversely with elevator height for better maneuverability. - Algae Detection Feature: implement algae effect current detection and hold behavior to enhance safety. - Controller inputs and setpoints: dynamic intake button, remapped elev+arm setpoints to operator, added center modules cmd to operator controller, updated to PS5 controller, added rest setpoint, and adjusted handoff flow to move to rest setpoint after. - Handoff timing: introduced a fixed 0.5s wait between handoff steps to improve reliability. - Safety and maintenance: elevator min height safeties adjustments, hasAlgae safety, cleanup like removing unused methods/imports, linting fixes, and constants refactor. Major bugs fixed: - End Effector Command Refactor: internal directory reorganization and wiring/import fixes to end effector commands; constants naming alignment and trigger bindings. - Funnel Subsystem: fix indexer intake logic, access modifiers corrections, and code comments. - Elevator/Arm safety: fix elevator minimum height safeties and revert arm safety behavior; zero arm angle fix. - Code cleanup: removed unused methods/imports and linting cleanup. - Algae handling: fix low algae enum handling and funnel outtake speed adjustments; update hasAlgae methods; safety to prevent zero-position when algae detected. - Debounce spike relocation and miscellaneous stabilization: moved debounce current spike check to end effector subsystem; removed unused code paths. Overall impact and accomplishments: - Significantly improved robot reliability, safety, and operator control in high-risk scenarios (algae, zero-position, safety interlocks) while reducing code debt and improving maintainability through refactors and cleanup. - Accelerated development cadence via clearer command structure, better wiring consistency, and more predictable handoff/timing behavior. - Delivered concrete business value by enabling more repeatable deployments, safer autonomous modes, and smoother operator control in competition-ready configurations. Technologies/skills demonstrated: - Command-based architecture, end effector modularization, and internal reorganization for maintainability. - Safety hardening and state management (elevator, arm, algae handling). - Advanced input handling and control scaling (swerve/joystick scaling with elevation). - Code quality practices: linting, constants management, cleanup, and documentation improvements.
