为可变形物体操作设计新分类体系,提升机器人抓取与操控的精细化描述能力。

T-DOM: A Taxonomy for Robotic Manipulation of Deformable Objects

  • 基于机器人运动、力、抓握/非抓握交互及物体形变,构建多维度分类框架
  • 在10类可变形物体任务中验证,能区分传统分类未识别的操作技能
  • 适合研究可变形物体操控的算法设计与机器人系统开发人员参考

机器人抓取与操作的分类体系常借鉴人类操作策略,对夹持器设计和算法开发具有指导意义。然而现有分类多假设物体刚性,难以描述可变形物体操作中的复杂互动。为此,本文提出T-DOM分类体系,分析机器人运动、作用力、抓握与非抓握交互,并首次对物体形变进行详细分类。为评估该体系,我们构建了一个包含10个任务的数据集,涵盖衣物、绳索、手术手套等可变形物体及多种形变类型。对比分析表明,T-DOM能有效区分其他分类体系未能识别的操作技能,适用于不同可变形物体与操作动作。该分类体系显著扩展了以往工作,提供更细粒度的描述能力,为推进可变形物体操作奠定理论基础,连接理论认知与实际机器人系统实现。

原文摘要 · Abstract (English)

Robotic grasp and manipulation taxonomies, inspired by observing human manipulation strategies, can provide key guidance for tasks ranging from robotic gripper design to the development of manipulation algorithms. The existing grasp and manipulation taxonomies, however, often assume object rigidity, which limits their ability to reason about the complex interactions in the robotic manipulation of deformable objects. Hence, to assist in tasks involving deformable objects, taxonomies need to capture more comprehensively the interactions inherent in deformable object manipulation. To this end, we introduce T-DOM, a taxonomy that analyses key aspects involved in the manipulation of deformable objects, such as robot motion, forces, prehensile and non-prehensile interactions and, for the first time, a detailed classification of object deformations. To evaluate T-DOM, we curate a dataset of ten tasks involving a variety of deformable objects, such as garments, ropes, and surgical gloves, as well as diverse types of deformations. We analyse the proposed tasks comparing the T-DOM taxonomy with previous well established manipulation taxonomies. Our analysis demonstrates that T-DOM can effectively distinguish between manipulation skills that were not identified in other taxonomies, across different deformable objects and manipulation actions, offering new categories to characterize a skill. The proposed taxonomy significantly extends past work, providing a more fine-grained classification that can be used to describe the robotic manipulation of deformable objects. This work establishes a foundation for advancing deformable object manipulation, bridging theoretical understanding and practical implementation in robotic systems.
