From Solo to Ensemble: A Hierarchical Framework for Composable Multi-Agent Human-Object Interaction

We propose a hierarchical framework that converts a single-agent HOI policy into a reusable Object-oriented Motion Skill.

Key points

  • Physics-based human-object interaction has achieved robust single-agent manipulation skills, yet extending them to multi-agent cooperative tasks remains challenging.
  • Existing approaches typically adapt interaction policies through task-specific fine-tuning, which entangles low-level contact-rich execution with high-level coordination and limits reuse across object geometries, interaction types, and team sizes.
  • Specifically, we reinterpret teacher rollouts as object-oriented action supervision by extracting short-horizon object-proxy motions from executed trajectories, and distill task-specific teachers into a low-level skill operating in an Object-oriented Action Space.
  • This formulation shifts multi-agent HOI learning from direct contact-rich full-body control to compact object-level proxy-motion coordination.
