CUHK's Orchestra robot framework completes 7.35-step subtask sequences

CUOHK · hf · 2026-10-14

Researchers from CUHK, Xiaomi and NUDT introduce Orchestra, an agent harness for long-horizon robotic manipulation: it decomposes multimodal instructions into ordered subtasks, tracks progress, and updates object locations via a shared context, with a separately trained progress evaluator deciding when to advance. They also release the RMBench-Compose benchmark. Orchestra hits 68.22% mean success across nine RMBench tasks (+26.22 points over Mem-0), achieves an Average Success Length of 7.35 subtasks (2.46x HarnessVLA) on RMBench-Compose, and improves real-world ASL by 25% over the base π0.5 policy. Code and project page are open-sourced.
