Skill-Space Shooting: Autonomous Robot Policy Improvement Guided by Foundation Models
技能空間射擊演算法：利用基礎模型引導機器人自主進行策略優化
Traditional robot policy correction relies heavily on human demonstrations. This paper proposes 'skill-space shooting,' which leverages foundation models to guide exploration over a set of reusable, short-horizon skills. When a robot encounters a failure, the system searches ('shoots') within this skill space to find a successful recovery path, turning successful trials into policy improvement data and enabling autonomous learning.
Key points
Autonomous Correction
Robots can autonomously explore and correct policy failures without requiring step-by-step human demonstrations.
Foundation Model Guidance
Uses the reasoning capabilities of foundation models to guide efficient search within the designated skill space.
Reusable Skill Space
Defines short behaviors as cross-task skills, allowing corrective experiences to be shared and reducing teaching requirements for new tasks.
How it works
Why it matters
This approach addresses a critical bottleneck in deploying physical robots: the heavy reliance on human intervention for corrections. By connecting high-level foundation model reasoning with low-level policy optimization, robots can continuously self-improve in real-world scenarios, enabling scalable and generalizable autonomous learning.
