During January 2025, 7strbass worked on the facebookresearch/habitat-lab repository, focusing on stabilizing the migration of the core vector library from Eigen to Magnum vectors. They addressed compatibility issues by refactoring quaternion conversions and ensuring that position data was consistently managed as NumPy arrays, which preserved numerical correctness throughout the simulation stack. Using Python and leveraging skills in robotics and vector math, 7strbass implemented a targeted stability fix that reduced migration risk and maintained data integrity. This work laid the foundation for broader modernization of the vector stack, improving maintainability and test coverage during a critical phase of the transition.
