In May 2025, Masaki Kuri developed foundational hazard light signaling features for Autoware, focusing on safety-critical integration across the tier4/autoware_launch and technolojin/autoware.universe repositories. He designed and implemented a ROS 2-based Hazard Lights Selector Package and a Command Aggregator Node, enabling configurable update rates and merging commands from both planning and system sources. Using C++, YAML, and embedded systems expertise, Masaki ensured reliable, parameter-driven hazard signaling that supports automated responses. His work addressed essential gaps in cross-component communication, providing a robust, production-ready framework for hazard light control and demonstrating depth in system configuration and design.
