摘要:

辅助机器人操作臂对于残障人士正变得越来越重要。在日常琐碎任务中遥操作操作臂是他们日常生活的一部分。与其通过所有动作来操控机器人,应用自行录制的运动宏可以极大地促进重复性任务的执行。动态运动基元(DMP)是通过遥操作进行技能学习的一种强大方法。然而,对于这种用例,它们需要简单的启发式规则来指定技能的起始、停止和参数化,而无需计算机科学背景和用于自主感知的学术传感器设置。为实现这一目标,本文提出了局部、全局和混合技能的概念,这些技能构成了组合单手日常生活任务的模块化基础。这些技能被隐式地指定,并且可以由用户自己轻松编程,仅需他们的基本机器人操作臂。本文贡献了所有与机器人无关的实现细节。实验验证了所开发方法在示例任务中的有效性,例如抓挠痒处、整理桌面上的物品以及向存钱罐中投硬币。本文附带了一个开源实现,网址为 https://github.com/fzi-forschungszentrum-informatik/ArNe。

英文摘要:

Assistive robotic manipulators are becoming increasingly important for people with disabilities. Teleoperating the manipulator in mundane tasks is part of their daily lives. Instead of steering the robot through all actions, applying self-recorded motion macros could greatly facilitate repetitive tasks. Dynamic Movement Primitives (DMP) are a powerful method for skill learning via teleoperation. For this use case, however, they need simple heuristics to specify where to start, stop, and parameterize a skill without a background in computer science and academic sensor setups for autonomous perception. To achieve this goal, this paper provides the concept of local, global, and hybrid skills that form a modular basis for composing single-handed tasks of daily living. These skills are specified implicitly and can easily be programmed by users themselves, requiring only their basic robotic manipulator. The paper contributes all details for robot-agnostic implementations. Experiments validate the developed methods for exemplary tasks, such as scratching an itchy spot, sorting objects on a desk, and feeding a piggy bank with coins. The paper is accompanied by an open-source implementation at https://github.com/fzi-forschungszentrum-informatik/ArNe
