Agent-Client Protocol Proposed as Standard for Human-Robot Interaction in GenAI Architectures

Jul 17, 2026

A new preprint proposes adopting the Agent-Client Protocol (ACP) as a unified communication standard for the human-robot interaction (HRI) layer in agent-based robotic systems. By combining ACP with the Model Context Protocol (MCP), the authors introduce a decoupled three-layer architecture that separates human interaction, deliberative orchestration, and physical execution. Experiments on a physical mobile robot demonstrate interoperability across three different user interfaces with negligible latency overhead.

Why it matters: Standardizing the HRI layer could reduce fragmentation and enable more flexible, real-time human-in-the-loop collaboration in robotic systems.
