PROFILE
Fu Zhengyu
Zhengfu Aj worked on the PDM4AR/exercises repository, delivering features that enhanced collision detection, geometric primitives, and dependency validation for robotics simulations. Using Python and C++, Zhengfu introduced a capsule geometric primitive with transformation and visualization methods, improved polygon validation, and implemented convex optimization-based collision detection to increase reliability. The work included refactoring and documentation updates to clarify module goals and improve maintainability, as well as enforcing forbidden-dependency checks through a robust validation layer. Zhengfu’s contributions focused on code quality, data structure robustness, and developer-facing documentation, resulting in a more maintainable and reliable codebase for simulation exercises.

Oct 1, 2025October 2025 focused on strengthening the robustness of dependency validation in the PDM4AR/exercises project. Delivered a targeted refactor of the Exercise 06 implementation validator, introducing an impl_validator attribute and a disallowed_validator function to enforce dependency checks more robustly and to improve error reporting for disallowed dependencies. This enhances the reliability of the validation layer, reduces debugging time in CI, and lays groundwork for easier extension of validation rules going forward. The change was committed as Refactor/ex06 impl validator (#146) with hash d30f6b188031dcb288bb70cd03dd298f2da8a3fb.
