人形机器人开发者终于有了一个更直观、通用的控制接口——HANDOFF 通过蒸馏多个专家模型,让机器人能同时做好行走、操作和跌倒恢复,做机器人全身控制的团队可以直接参考其方法。
HANDOFF 提出了一种紧凑、直观的接口,用于人形机器人的任务规划与全身控制之间的连接。该接口通过多教师 KL 蒸馏和上下文条件门控机制,将三个互补专家(全身运动跟踪、行走、跌倒恢复)蒸馏成一个混合专家学生模型。在 Unitree G1 机器人上,HANDOFF 实现了与最先进方法相当的行走速度跟踪,并提供了最大的鲁棒操作工作空间之一。此外,通过 VLM 驱动的智能体规划器,无需任务特定数据或控制器微调,即可实现自然语言驱动的任务执行。这项工作为人形机器人在现实世界中的部署提供了更高效、更通用的控制方案。
HANDOFF: Humanoid Agentic Task-Space Whole-Body Control via Distilled Complementary Teachers
For a humanoid robot to be deployed in the real world, the choice of command space (i.e., the interface between task planning and whole-body control) is crucial. Existing whole-body controllers typically demand dense kinematic or spatial references that planners struggle to synthesize from task semantics. We instead propose a compact, explicit interface that is intuitive, general, modular, and expressive enough for diverse manipulation skills. To this end, we introduce HANDOFF, a single humanoid whole-body controller that follows this interface and is distilled via multi-teacher KL distillation under a context-conditioned gating scheme into a mixture-of-experts student from three complementary specialists: whole-body motion tracking with safety-filtered data, locomotion, and fall-recovery. On the Unitree G1, HANDOFF matches state-of-the-art velocity tracking and offers one of the largest robust manipulation workspaces. We further demonstrate hardware feasibility through multiple natural-language-driven task roll-outs, powered by a VLM-driven agentic planner with no task-specific data or controller fine-tuning.
