Abstract

Collaborative human-robot task execution approaches require mutual adaptation, allowing both the human and robot partners to take active roles in action selection and role assignment to achieve a single shared goal. Prior works have utilized a leader-follower paradigm in which either agent must follow the actions specified by the other agent. We introduce the User-aware Hierarchical Task Planning (UHTP) framework, a communication-free human-robot collaborative approach for adaptive execution of multi-step tasks that moves beyond the leader-follower paradigm. Specifically, our approach enables the robot to observe the human, perform actions that support the human’s decisions, and actively select actions that maximize the expected efficiency of the collaborative task. In turn, the human chooses actions based on their observation of the task and the robot, without being dictated by a scheduler or the robot. We evaluate UHTP both in simulation and in a human subjects experiment of a collaborative drill assembly task. Our results show that UHTP achieves more efficient task plans and shorter task completion times than non-adaptive baselines across a wide range of human behaviors, that interacting with a UHTP-controlled robot reduces the human’s cognitive workload, and that humans prefer to work with our adaptive robot over a fixed-policy alternative.
http:面向无通信、相互适应的人机协作的用户感知分层任务规划框架
协作式人机任务执行方法需要相互适应,允许人和机器人合作伙伴在行动选择和角色分配中发挥积极作用,以实现单一的共享目标。先前的研究使用了领导者-追随者范式,其中任何一个代理都必须遵循另一个代理指定的动作。我们介绍了用户感知分层任务规划(http)框架,这是一种无需通信的人机协作方法,用于自适应执行多步骤任务,超越了领导者-追随者范式。具体来说,我们的方法使机器人能够观察人类,执行支持人类决策的动作,并主动选择最大限度提高协作任务预期效率的动作。反过来,人类根据他们对任务和机器人的观察来选择行动,而不受调度程序或机器人的支配。我们在模拟和协作演练装配任务的人类受试者实验中评估UHTP。我们的研究结果表明,在广泛的人类行为中,与非自适应基线相比,uhttp实现了更有效的任务计划和更短的任务完成时间,与uhttp控制的机器人交互减少了人类的认知工作量,并且与固定策略替代方案相比,人类更喜欢与我们的自适应机器人一起工作。

期刊介绍: ACM Transactions on Human-Robot Interaction (THRI) is a prestigious Gold Open Access journal that aspires to lead the field of human-robot interaction as a top-tier, peer-reviewed, interdisciplinary publication. The journal prioritizes articles that significantly contribute to the current state of the art, enhance overall knowledge, have a broad appeal, and are accessible to a diverse audience. Submissions are expected to meet a high scholarly standard, and authors are encouraged to ensure their research is well-presented, advancing the understanding of human-robot interaction, adding cutting-edge or general insights to the field, or challenging current perspectives in this research domain. THRI warmly invites well-crafted paper submissions from a variety of disciplines, encompassing robotics, computer science, engineering, design, and the behavioral and social sciences. The scholarly articles published in THRI may cover a range of topics such as the nature of human interactions with robots and robotic technologies, methods to enhance or enable novel forms of interaction, and the societal or organizational impacts of these interactions. The editorial team is also keen on receiving proposals for special issues that focus on specific technical challenges or that apply human-robot interaction research to further areas like social computing, consumer behavior, health, and education.
