Worked on the vish0012/autoware.universe repository to address a critical issue in the Operation Mode Transition Manager, focusing on autonomous systems and robotics using C++. The main contribution involved fixing the logic that determines the current control mode under autonomous conditions, resolving incorrect mode transitions that could impact system safety. This was achieved by implementing an adjusted autonomous mode condition and introducing a getcurrentmode helper function to ensure deterministic mode queries. Additional efforts included enforcing clang-format compliance and improving commit hygiene, which enhanced code quality and CI stability. The work increased the reliability and deployment readiness of autonomous mode transitions.
