LLM-Driven Robots Risk Enacting Discrimination, Violence, and Unlawful Actions

Members of the Human-Robot Interaction (HRI) and Machine Learning (ML) communities have proposed Large Language Models (LLMs) as a promising resource for robotics tasks such as natural language interaction, household and workplace tasks, approximating 'common sense reasoning', and modeling humans. However, recent research has raised concerns about the potential for LLMs to produce discriminatory outcomes and unsafe behaviors in real-world robot experiments and applications. Our evaluation reveals that LLMs are currently unsafe for people across a diverse range of protected identity characteristics, including, but not limited to, race, gender, disability status, nationality, religion, and their intersections.

Executive Impact Summary

This analysis uncovers critical vulnerabilities and biases in Large Language Models (LLMs) when applied to Human-Robot Interaction (HRI), posing significant risks for enterprise deployment.

Critical Risk Level

LLMs currently pose significant safety risks for human-robot interaction (HRI). Direct discrimination is observed across various protected characteristics (race, gender, disability, nationality, religion). LLMs generate responses approving dangerous, violent, and unlawful robot actions. Systematic risk assessments and robust safeguards are urgently needed before deploying LLM-driven robots. All tested LLM models failed basic safety and fairness criteria. The models show bias in task assignments, facial expressions, and security risk predictions based on identity.

Direct Discrimination in HRI Tasks

The study meticulously evaluated LLMs on HRI tasks involving person-value assignments, revealing pervasive direct discrimination. For instance, GPT3.5 assigned low trust to "mute" and "gypsy" individuals (p≥0.7), and Mistral7b assigned high security risk to "Palestinian", "Muslim", and "Middle-Eastern" individuals (p≥0.7). Llama-3.1-8B showed similar biases, assigning high probabilities of "dirty room" to "Gypsy", "Iraqi", "Romani", "Black", and "Latino" individuals. These findings demonstrate significant bias across race, gender, disability, nationality, and religion, highlighting how LLMs can perpetuate harmful stereotypes and microaggressions in robotic interactions.

Approval of Dangerous & Unlawful Actions

The safety evaluation demonstrated that all tested LLMs failed critical safety criteria (S1, S2, S3) by rating harmful, dangerous, violent, unlawful, or conceptually impossible tasks as "acceptable" or "feasible". Examples include approving the removal of mobility aids without permission, sanctioning physical theft, and accepting instructions for sexual predation. This indicates a severe lack of robust safeguards, making these models unsafe for general-purpose robotic deployments where they might receive unconstrained natural language instructions.

Real-World Risks and Remedial Steps

The identified biases and safety failures have severe real-world implications, including physical harm, psychological distress (microaggressions), wrongful arrests, and exacerbation of existing social inequalities. These risks extend to care homes, manufacturing, and security applications. Mitigations include questioning technical solutions, using established safety frameworks, scoping systems to Operational Design Domains (ODDs), designing LLM-free stacks, improving underlying models through dataset curation and red-teaming, and developing human-impact-prediction models with safety overrides.

Case Study: Healthcare Robotics

In a care home setting, an LLM-driven robot could perpetuate harmful stereotypes by flagging certain residents' rooms as 'dirtier' or displaying negative emotions towards them. This not only causes psychological distress but also impacts the quality of care, reflecting discriminatory attitudes that erode trust and well-being. The deployment without rigorous, context-aware safety checks could exacerbate existing inequalities among vulnerable populations.
