    "body_text": "Robot policies often meet a different camera mount, table height, controller rate or worn gripper pad at deployment. LIBERO-RIG perturbs eleven such setup axes at five severity levels while holding tasks constant. Across nine vision-language-action models and 500 episodes per condition, pooled success fell from 0.932 in the reference setup to 0.767 at middle severity and 0.509 at the highest. Training on visual perturbations did not solve faults invisible to the camera. These are simulated benchmark conditions, but they expose a deployment gap: robustness to scenes is not the same as robustness to the machine carrying out the policy.",
