During September 2025, Zhang Zr contributed to the TianxingChen/Embodied-AI-Guide repository by expanding the CMU 16-745 Optimal Control resources within the project’s README. Focusing on documentation using Markdown, Zhang enriched the onboarding and self-learning experience by integrating a new course website link and multimedia assets from YouTube and Bilibili. The updates were delivered through clear, incremental commits that maintained high documentation standards and improved accessibility for new contributors. While no bugs were addressed during this period, the work demonstrated depth in curating and organizing technical resources, supporting the team’s goal of providing up-to-date, comprehensive learning materials.
