Irene Xu developed HD Map Lanelet and Object Data Services for the WATonomous/wato_monorepo, enhancing the system’s ability to provide detailed lane-level and object data for navigation. She implemented new C++ APIs within the ROS framework, enabling richer map visualization and more precise object retrieval. Her work included updating documentation, refining configuration files, and maintaining delivery hygiene to ensure clarity and usability. By untracking unnecessary files and improving service documentation, Irene contributed to a more maintainable codebase. The depth of her contributions reflects a focus on robust API development and practical integration of map data services for autonomous navigation systems.
