NEXUS framework enhances safety for embodied AI planning

By PulseAugur Editorial · [1 sources] ·

Researchers have developed NEXUS, a novel neuro-symbolic framework designed to enhance the safety and robustness of embodied agents that plan using natural language instructions. This framework jointly maintains a PDDL domain model for action schemas and an LTL safety specification for constraints. By converting execution failures and detected hazards into reusable LTL constraints, NEXUS improves action feasibility and reduces hazardous outcomes. Experiments on the SafeAgentBench evaluation set demonstrate that NEXUS offers a superior balance between task completion and refusal of unsafe actions, while also showing resilience against jailbreak attacks. AI

IMPACT This framework could lead to safer and more reliable AI agents in physical environments, reducing risks associated with autonomous systems.

    NEXUS: Learning Safety Constraints and Action Models for Safe and Robust Embodied Planning

    arXiv:2605.09387v2 Announce Type: replace Abstract: Large language models (LLMs) enable embodied agents to plan from naturallanguage instructions, yet their actions may be physically infeasible or hazardous. Existing neuro-symbolic learners primarily refine execution models, whil…
