During December 2024, Juan Llorens expanded data collection capabilities for the UniversumX/Universum repository by integrating a large sensor dataset, including accelerometer and EEG raw data, into the existing data ingestion workflow. He established an organized assets library containing audio and image files to support both data capture and demonstration needs. Using CSV as the primary data format, Juan focused on data engineering and asset management, ensuring all changes were traceable through disciplined version control practices. While no major bugs were addressed during this period, his work improved data availability for analysis and model development, laying groundwork for future enhancements.
