通过几何特征迁移,让机器人学会用不同形状的同类物品完成复杂操作。

GIFT: Geometry-Induced Functional Transfer for Category-level Object Manipulation

  • 基于人类示范提取物体中心交互的几何表示
  • 可在形状差异大的同类物体间成功转移操作技能
  • 适合需要快速适应新物品的现实场景机器人应用

机器人在陌生环境中操作不熟悉物体面临泛化能力不足的挑战。本文提出一种新的技能迁移框架 GIFT(Geometry-Induced Functional Transfer),使机器人仅需一次人类示范即可迁移复杂操作技能与约束。该方法通过聚焦物体-环境交互,从示范中提取几何表征,并借助功能映射(FMC)框架高效建立对象间交互函数映射,实现对具有相似拓扑结构但形状显著不同的同类物体的操作复制。此外,引入螺旋插值(ScLERP)生成平滑、几何感知的机器人运动路径,确保迁移技能符合原始任务约束。大量实验证明,本方法在多种真实场景中无需额外训练即可成功实现技能迁移与任务执行。

原文摘要 · Abstract (English)

Robotic manipulation of unfamiliar objects in new environments is challenging due to limited generalisation capabilities. We propose a new skill transfer framework, GIFT (Geometry-Induced Functional Transfer), which enables a robot to transfer complex object manipulation skills and constraints from a single human demonstration. Our approach addresses the challenge of skill acquisition and task execution by deriving geometric representations from demonstrations focusing on object-centric interactions. By leveraging the Functional Maps (FMC) framework, we efficiently map interaction functions between objects and their environments, allowing the robot to replicate task operations across objects of similar topologies or categories, even when they have significantly different shapes. Additionally, our method incorporates screw interpolation (ScLERP) for generating smooth, geometrically-aware robot paths to ensure the transferred skills adhere to the demonstrated task constraints. We validate the effectiveness and adaptability of our approach through extensive experiments, demonstrating successful skill transfer and task execution in diverse real-world environments without requiring additional training.
