Worked on the isaac-sim/IsaacLab repository to improve the reliability of camera demo image exports by addressing a bug in the save_images_grid function. The solution involved updating the Python code to correctly handle single-subplot axes generated by plt.subplots(1, 1), preventing AttributeError and ensuring images are saved properly in both local and CI environments. This change enhanced the stability of demo workflows for users and automated pipelines. The fix was validated through pre-commit checks and aligned with project contribution guidelines. Core skills applied included Python scripting, bug fixing, and data visualization, with follow-up documentation and testing planned.
