Guardian: Detecting Robotic Planning and Execution Errors with Vision-Language Models

The study proposes an automatic framework for generating robotic planning and execution failure data, builds the GuardianFail-36k failure reasoning dataset based on RLBench and BridgeDataV2, and trains Guardian, a multi-view reasoning vision-language model. Guardian achieves state-of-the-art performance on three unseen real-world benchmarks: RoboFail, RoboVQA, and the newly introduced UR5-Fail. When combined with LLM-based manipulation policies, it improves task success rates in both simulation and real-world deployment. Code, data, and models are publicly available.
