摘要:

虽然远程呈现辅助机器人已经取得了重大进展,但它们仍然缺乏远程操作员的真实感和物理存在感。这导致了对这种机器人缺乏信任和采用。在本文中,我们介绍了一个化身机器人系统,这是一个混合的真实/虚拟的机器人系统,物理上与一个人在机器人附近的互动。机器人结构与远程护理人员的3D模型重叠,并通过增强现实(AR)进行可视化。通过这种方式,人接收触觉反馈,因为机器人触摸他/her. We进一步提出了一个最佳的非迭代对齐求解器,解决了最佳对齐姿态的3D人体模型的机器人(肩到手腕非迭代)。拟议的对齐求解器是无状态的,实现了最佳对齐,比基线求解器更快(在我们的评估中证明)。我们还提出了一个评估框架,通过多方面的指标量化的求解器的对齐质量。我们表明,我们的求解器可以始终如一地产生类似或优越的路线作为IK-based基线,而没有潜在的缺点。

英文摘要:

Although telepresence assistive robots have made significant progress, they still lack the sense of realism and physical presence of the remote operator. This results in a lack of trust and adoption of such robots. In this paper, we introduce an Avatar Robot System which is a mixed real/virtual robotic system that physically interacts with a person in proximity of the robot. The robot structure is overlaid with the 3D model of the remote caregiver and visualized through Augmented Reality (AR). In this way, the person receives haptic feedback as the robot touches him/her. We further present an Optimal Non-Iterative Alignment solver that solves for the optimally aligned pose of 3D Human model to the robot (shoulder to the wrist non-iteratively). The proposed alignment solver is stateless, achieves optimal alignment and faster than the baseline solvers (demonstrated in our evaluations). We also propose an evaluation framework that quantifies the alignment quality of the solvers through multifaceted metrics. We show that our solver can consistently produce poses with similar or superior alignments as IK-based baselines without their potential drawbacks.
