Chloe Johnson developed and enhanced the climb subsystem for the femaidens/2025-Reefscape robotics project, focusing on both hardware migration and control logic improvements. She implemented a unified pulley system command with updated input mapping, refactored climb commands using inline lambda-based motor control, and migrated hardware between SparkMax, TalonFX, and REV Spark Max controllers. Her work included tuning speed constants, expanding rotational limits, and preparing for neutral drive modes, all in Java using command-based programming and embedded systems techniques. These contributions improved subsystem reliability, reduced maintenance risk, and established a robust foundation for future sensor integration and performance optimizations.

February 2025—For femaidens/2025-Reefscape, delivered core control enhancements for the climbing subsystem and unified input mapping, with a strategic hardware migration that reduces maintenance risk and improves reliability. Key features delivered: • Pulley System Command and Controller Binding implemented; unified pulley control and input mapping by binding to the right trigger, removing legacy brake/coast modes. • Climb Subsystem Enhancements and Hardware Migration: refactored climb commands using inline lambda-based motor control, tuned climb speed, adjusted neutral drive modes during climb, updated naming conventions and constants, and migrated hardware to REV Spark Max controllers and encoders. Business value: safer, more predictable climbs, easier future feature work, and groundwork for improved sensor feedback and performance. Major bugs fixed: none reported this period; focus on refactor and stability improvements to prevent regressions. Overall impact: reduced maintenance burden, improved climb reliability and predictability, and established a foundation for future optimizations. Technologies/skills demonstrated: inline lambda-based motor control, input binding and controller mapping, hardware migration to REV Spark Max, code refactoring, naming conventions.
