CHORUS uses a single VLA policy to control multi-robot teams for decentralized collaboration

Chelsea Finn's team fine-tuned a VLA so that a single policy can control any robot in a robot team, enabling multi-robot collaboration without explicit communication (the system described in the quoted tweet is named CHORUS). Results show that this method matches or outperforms training separate models for each robot or training a unified centralized model, and it scales easily to large teams.
