📝 摘要(中文)
视觉-语言-动作(VLA)模型将视觉观察和语言指令直接映射到机器人动作,但长时间任务需要的不仅仅是动作预测。代理必须协调感知、规划、执行、进度验证和恢复。我们提出了EmbodiedSkills,一个统一框架,将每个技能决策视为执行提案:在执行前检查其前提条件,并在执行后验证结果。该框架通过共享的可执行技能接口连接高层技能选择、低层VLA执行和后续验证,支持低层策略的替换或适应而无需更改代理循环。我们在RoboTwin 2.0和LIBERO上实例化了EmbodiedSkills,任务适应的低层VLA策略在50个RoboTwin 2.0任务中平均成功率为86.20%,在四个LIBERO套件中为97.40%。
🔬 方法详解
问题定义:本论文旨在解决长时间任务中VLA代理在执行过程中的协调问题。现有方法往往只关注动作预测,缺乏对执行有效性和结果验证的全面考虑。
核心思路:EmbodiedSkills框架将每个技能决策视为执行提案,设计了一个固定的可执行技能接口,以便在执行前检查前提条件,并在执行后验证结果,从而增强了代理的执行能力。
技术框架:该框架包括高层技能选择、低层VLA执行和后续验证三个主要模块。通过共享的接口,这些模块在单一代理循环中协同工作,确保了执行过程的连贯性和有效性。
关键创新:EmbodiedSkills的最大创新在于其统一的可执行技能接口,使得低层VLA策略可以灵活替换或适应,而不需要更改整个代理的执行循环。这种设计显著提高了系统的可维护性和扩展性。
关键设计:在实现中,框架记录了规划、执行、验证和恢复事件,形成结构化轨迹,为各个组件提供监督,并支持在交互反馈可用时进行在线适应。

📄 摘要(原文)
Vision-language-action (VLA) models map visual observations and language instructions directly to robot actions, but long-horizon tasks require more than action prediction. An agent must coordinate perception, planning, execution, progress verification, and recovery as the physical state evolves. An action prediction or a model-generated skill decision does not, by itself, guarantee that the proposed operation is valid in the current state or that its outcome will be verified. We propose EmbodiedSkills, a unified framework that treats each skill decision as an execution proposal: the runtime checks its prerequisites before execution and verifies the outcome afterward. A shared executable-skill interface connects high-level skill selection, bounded low-level VLA execution, and post-action verification within a single agent loop. Because this interface remains fixed, low-level VLA policies can be replaced or adapted without changing the agent loop. The interface also records planning, execution, verification, and recovery events as structured trajectories, which provide supervision for individual components and can support optional online adaptation when interactive feedback is available. We instantiate EmbodiedSkills with Qwen3-VL and OpenPI/pi0.5 on RoboTwin 2.0 and LIBERO. Task-adapted low-level VLA policies achieve an average success rate of 86.20% across 50 RoboTwin 2.0 tasks and 97.40% across the four LIBERO suites. These results establish the execution performance of the task-adapted low-level VLA policies used in EmbodiedSkills. On four memory-dependent RMBench tasks, the same task-adapted execution approach achieves 12.5% average success. The framework provides a trainable and inspectable agent layer for turning these policies into closed-loop embodied systems.
