Abstract

Safe task-level manipulation requires a planner to recognize hazards, select appropriate mitigation actions, and satisfy their execution prerequisites without abandoning the original goal. We introduce ResponsibleRobotBench, a benchmark of 23 manipulation task configurations with separately specified goals and safety conditions. It connects hazard-category predictions, planned actions, execution feedback, and terminal outcomes at the episode level. Across evaluations of five large multimodal models, terminal safety and safe task completion can diverge: defense prompts increase terminal safety for three tested models but affect safe success in different directions. Correct hazard-category predictions also fail to ensure executable mitigation. In a cutting task under the default configuration, GPT-4o mini identifies the human hazard in all 100 episodes but never requests assistance, and every episode ends unsafe. Offering a help action and actually requesting it lead to different comparisons: outcomes differ between action menus even for a model that never requests help, and repeated requests can leave execution failures unresolved. Imitation-learning evaluations and physical robot sequences illustrate the need to coordinate mitigation with goal actions. Together, these results motivate evaluating mitigation selection, action prerequisites, and recovery alongside hazard recognition and terminal outcomes. The appendix provides task definitions, checker conditions, and prompts. Project website: https://responsible-robot-benchmark.github.io/.

TABLE II: Benchmark definitions: (a) system boundary; (b) all 23 task configurations. E: electrical; F: fire/chemical; H: human-related. Hazard indicates a task hazard source, not the terminal safety outcome. Controls are hazard-free. Subtask counts describe the nominal robot sequence, excluding optional assistance; UNS goals have no safe completion horizon.

Fig. 2: Watering tasks with different hazards and grasps. water1 and water3 contain a power strip; water2 and water4 do not. water1 and water2 use the side handle, while water3 and water4 use the top handle. TCP denotes tool center point.

Fig. 3: Task classification by whether the goal can be achieved safely. Illustrative normal and defense instructions for a COS goal are shown on the left; an inherently harmful UNS request and its safe response are shown on the right. Defense-prompt comparisons are conducted on COS tasks only.

Fig. 4: Evaluation system. (a) Planner boundary and benchmark observation, action, execution, and evaluation interfaces. (b) Reference-system data flow: execution feedback informs subsequent planning, while separate safety and success checkers produce outcome labels.

Fig. 5: Overview of outcomes. Panels (a) and (b) show high-level-skill Safe, Succ, and SSR, with mean dimensionless Cost reported numerically on its original scale. Both give equal weight to the three hazard categories; (a) covers hazardous COS tasks and (b) hazard-free controls. Panel (c) shows hazard-category accuracy across all 23 tasks (Table VI ). Panel (d) gives an episode-flow breakdown: 88.0% have correct goals and 12.0% invalid goals. Percentages in the right-hand boxes are conditional on the corresponding goal branch.

TABLE XI: Results by subtask count for 18 conditionally safe and hazard-free tasks. The five inherently unsafe tasks are evaluated through safety and refusal decisions rather than goal-execution horizons. One subtask: push2; two: charge2, cutfruit1, cutfruit2, put1, put2, extinguish2, light2, water2, water4; three: charge1, push1, heat2; four: extinguish1, light1, water1, water3; five: heat1.

Fig. 11: Imitation-policy terminal safety, success, and safe success on six tasks. water1, water3, and light1 contain hazards; the other tasks are their hazard-free variants.

Multimodal Large Language Models are increasingly adopted as autonomous agents in interactive environments, yet their ability to proactively address safety hazards remains insufficient. We introduce SafetyALFRED, built upon the embodied agent benchmark ALFRED, augmented with six categories of real-world kitchen hazards. While existing safety evaluations focus on hazard recognition through disembodied question answering (QA) settings, we evaluate eleven state-of-the-art models from the Qwen, Gemma, and Gemini families on not only hazard recognition, but also active risk mitigation through embodied planning. Our experimental results reveal a significant alignment gap: while models can accurately recognize hazards in QA settings, average mitigation success rates for these hazards are low in comparison. Our findings demonstrate that static evaluations through QA are insufficient for physical safety, thus we advocate for a paradigm shift toward benchmarks that prioritize corrective actions in embodied contexts. We open-source our code and dataset under https://github.com/sled-group/SafetyALFRED.git
