During April 2025, TianxingChen focused on maintaining and improving documentation quality for the TianxingChen/Embodied-AI-Guide repository. The primary engineering task involved identifying and fixing a broken RT-1 arXiv link in the README, which previously hindered users from accessing the referenced paper. Using Markdown and git, TianxingChen validated the new link to ensure it directed readers to the correct arXiv identifier, thereby enhancing the repository’s usability for researchers. The work demonstrated attention to documentation hygiene and link validation, contributing to a more reliable user experience. No new features or API changes were introduced, reflecting a targeted approach to documentation stability.
