RoboCasa-Shift: Stage-Aware Robustness Evaluation of Vision-Language-Action Policies in Long-Horizon Household Manipulation
NVIDIA's GR00T N1.5 robot model completed 73.8% of four long household tasks in simulation, but its success fell to 0% under the strongest image blur and outcome flips that cancel each other hid real sensitivity in other tests, a Fudan-led team reports in a preprint introducing the RoboCasa-Shift benchmark. Under a mild camera shift the success rate did not move, yet 8 of 80 matched episodes changed result.
