Monthly summary for 2025-04: This period focused on delivering realistic simulation assets, stabilizing build and dependency management, and enhancing user interfaces and real-time visualization across robotics platforms. In RoboticsInfrastructure, Grass Environment Assets and Visuals were delivered with newly added grass textures and assets, asset reorganization, and updated references to ensure consistent visuals and environmental realism. A directional lighting feature was introduced to illuminate the 3D world without adding visible light objects, improving scene quality. In RoboticsAcademy, build stability was strengthened by re-adding essential ROS dependencies, updating subproject references, pinning OMPL from sources, and updating installation scripts, ensuring reliable and up-to-date dependencies. Front-end UI/UX improvements for computer vision exercises were completed, including a polished UI for the follow-person exercise, a Basic Computer Vision template, and an improved camera visualizer in the CV exercise. GUI stability fixes were implemented to address missing declarations and reset behaviors in real-time visualization, and codebase cleanup plus backend refactors removed deprecated API endpoints and streamlined code paths. Overall, these changes improve simulation fidelity, development reliability, and user experience, accelerating testing, training, and deployment workflows.
