Worked on the hyundai-robotics/doc-hi6-operation repository to address a documentation bug by clarifying the R115 usage constraint message. Focused on improving operator guidance, the update specified that the code must be used when the program is stopped, rather than in manual mode, aligning documentation with actual operational constraints. The change was implemented using Markdown and emphasized precise, regression-safe documentation practices without altering any code paths. This approach reduced the risk of misuse and potential support inquiries by enhancing user understanding of safety requirements. Demonstrated attention to detail and strong documentation skills, ensuring technical accuracy and alignment with operational guidelines.
