During a two-month period, Phinjo Hyolmo developed and enhanced the climb subsystem for the femaidens/2025-Reefscape robotics repository, focusing on embedded systems and Java. He implemented encoder-based rotation control with defined safety limits, enabling deterministic motor movement and reducing drift, which improved both precision and operator safety. In the following month, he delivered motor neutral mode control, allowing the climb motors to switch between brake and coast modes via controller inputs and ensuring braking behavior within rotation limits. Throughout, Phinjo prioritized feature delivery and code quality, demonstrating depth in robotics control systems without major bug fixes required.
