Developed advanced autonomous navigation and mapping features for the ArcturusNavigation/all_seaing_vehicle repository, focusing on robust obstacle detection, buoy tracking, and simulation-driven validation. Leveraging Python, C++, and ROS 2, the work included implementing scanline-based grid map generation, PID control for buoy following, and adaptive waypoint logic to improve real-time decision-making and mission reliability. Integrated multi-threaded processing, parameter tuning, and object-oriented design to enhance navigation stability and maintainability. Addressed edge cases such as intermittent obstacle disappearance and improved codebase organization through targeted refactoring. The engineering approach emphasized iterative testing, traceable commits, and scalable solutions for dynamic maritime environments.
