视觉-语言-动作(VLA)模型通过集成动作生成模块,扩展了视觉-语言模型(VLM)在机器人操作中的应用。依托VLM在视觉感知和指令理解方面的优势,VLA模型展现出跨多样化操作任务的良好泛化能力。然而,在高精度、高准确度需求的应用中,性能差距仍明显,亟需进一步适应。多领域证据表明,后训练对对齐基础模型与下游任务至关重要,推动了大量关于VLA模型后训练的研究。本文从新埃尔的约束导向技能习得理论出发,将后训练方法系统归纳为四类:(i)增强环境感知,(ii)提升本体觉意识,(iii)深化任务理解,(iv)多组件整合。基于标准基准的实验结果被综合分析,提炼出可操作的优化建议。最后,梳理了当前开放挑战与新兴趋势,并结合人类学习规律,展望未来后训练方法的发展方向。本文不仅提供了从人类运动学习视角出发的全面综述,也给出了实际研发的指导价值。项目主页:https://github.com/AoqunJin/Awesome-VLA-Post-Training。

原文摘要 · Abstract (English)

Vision-language-action (VLA) models extend vision-language models (VLM) by integrating action generation modules for robotic manipulation. Leveraging the strengths of VLM in vision perception and instruction understanding, VLA models exhibit promising generalization across diverse manipulation tasks. However, applications demanding high precision and accuracy reveal performance gaps without further adaptation. Evidence from multiple domains highlights the critical role of post-training to align foundational models with downstream applications, spurring extensive research on post-training VLA models. VLA model post-training aims to enhance an embodiment's ability to interact with the environment for the specified tasks. This perspective aligns with Newell's constraints-led theory of skill acquisition, which posits that motor behavior arises from interactions among task, environmental, and organismic (embodiment) constraints. Accordingly, this survey structures post-training methods into four categories: (i) enhancing environmental perception, (ii) improving embodiment awareness, (iii) deepening task comprehension, and (iv) multi-component integration. Experimental results on standard benchmarks are synthesized to distill actionable guidelines. Finally, open challenges and emerging trends are outlined, relating insights from human learning to prospective methods for VLA post-training. This work delivers both a comprehensive overview of current VLA model post-training methods from a human motor learning perspective and practical insights for VLA model development.
