M2HRI: An LLM-Driven Multimodal Multi-Agent Framework for Personalized Human-Robot Interaction

Breenice Lee, Shaid Hasan, Sujan Sarker, Tariq Iqbal

Distinct robot personalities and long-term memory, coordinated by an LLM, produce more coherent and personalized multi-robot interactions with humans.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Together, these results demonstrate that both agent individuality and structured coordination are essential for coherent and socially appropriate multi-agent HRI.

C2weakest assumption

The controlled user study (n=105) findings on personality distinguishability, memory benefits, and coordination improvements generalize to real-world, long-term multi-robot interactions in social environments.

C3one line summary

M2HRI equips multi-robot teams with LLM-driven distinct personalities, long-term memory, and conditioned coordination, with a 105-participant study showing gains in distinguishability, personalization, and interaction quality.
