Why this framework?
Human-facing robots need more than perception, planning, and control. They need explicit context, memory governance, social validation, timing, style, embodiment binding, and feedback.
S.O.C.I.A.L. HML provides a layered design language for making these responsibilities visible, testable, replaceable, and governable.
Modern AI does not make HML obsolete. It makes semantic interfaces, responsibility boundaries, and layered validation more important.

A short introduction to the S.O.C.I.A.L. HML Framework and its role in inspectable, socially governed, modern-AI-compatible Human-Robot Interaction architectures.
Architecture at a glance
HML models the full path from interaction evidence to socially appropriate, platform-specific robot behavior.
Foundation models as bounded experts
LLMs, VLMs, agents, video models, RL policies, and end-to-end systems can all contribute to HRI. The key is to connect them through HIFs, gates, semantic commitments, and feedback rather than giving them unbounded authority.
From HRI consortium lessons to a research framework
S.O.C.I.A.L. HML was created by Dr. Eliahu Khalastchi as an independent synthesis of HRI architecture lessons, informed by applied R&D experience and the rapid shift toward foundation-model-based robotics.
The documentation is being developed alongside an academic paper on inspectable HRI architectures in the foundation-model era.
