摘要:

人-机器人协作任务预见了人类和机器人之间具有不同程度复杂性的交互。具体而言,对于涉及代理之间的物理接触的任务,在这种交互的建模和控制中出现了挑战。在本文中,我们提出了一个控制架构,能够确保灵活和鲁棒稳定的物理人机交互,专注于协同运输任务。该架构部署到移动机械手,建模为一个整体结构,这有助于操作员在运输笨重的负载。由于无源性技术,控制器在线调整其相互作用参数,同时保持整个系统的鲁棒稳定性,从而实验验证的架构。

英文摘要:

Human-robot collaborative tasks foresee interactions between humans and robots with various degrees of complexity. Specifically, for tasks which involve physical contact among the agents, challenges arise in the modelling and control of such interaction. In this paper we propose a control architecture capable of ensuring a flexible and robustly stable physical human-robot interaction, focusing on a collaborative transportation task. The architecture is deployed onto a mobile manipulator, modelled as a whole-body structure, which aids the operator during the transportation of an unwieldy load. Thanks to passivity techniques, the controller adapts its interaction parameters online while preserving robust stability for the overall system, thus experimentally validating the architecture.
