RORA presents an end-to-end pipeline for reconstructing simulation-ready articulated objects from a single static object video, avoiding the need to scan dynamic motion. It combines 3D Gaussian Splatting for photorealistic appearance with mesh geometry for physical interaction. The pipeline performs convex decomposition, human-guided part grouping, Gaussian-to-mesh binding, and automatic joint-axis suggestion based on local boundary geometry. The authors report precise articulation results on PartNet-Mobility-v0 and real objects, and demonstrate reconstructed assets in Unreal Engine and NVIDIA Isaac Sim for real-time dexterous-hand manipulation tasks.
