摘要

摘要:人机协作是人与机器人最佳技能的结合,在满足各领域安全、高效、灵活的需求方面显示出广阔的应用前景。人与机器人之间更紧密互动的理念极大地推动了数字孪生的探索,以加强协作。通过提供高保真模型和实时物理-虚拟交互,数字孪生能够实现对物理场景的准确反映,不仅包括人机条件,还包括环境变化。然而,不可预测事件的出现可能会导致既定计划与实际执行之间的不一致。针对这一问题,本文提出了一种基于数字孪生的人机协作环境自适应分配方法。该方法包括一个因素-事件-行为机制,从数字孪生体的内部和外部角度分析动态事件及其影响,以及一个基于遗传算法的分配算法来响应这些事件。最后进行了实验,旨在证明所提出方法的可行性。

A Digital Twin-based environment-adaptive assignment method for human-robot collaboration
Abstract Human-robot collaboration, which strives to combine the best skills of humans and robots, has shown board application prospects in meeting safe-effective-flexible requirements in various fields. The ideation of much closer interaction between humans and robots has greatly developed the exploration of digital twin to enhance the collaboration. By offering high-fidelity models and real-time physical-virtual interaction, digital twin enables to achieve an accurate reflection of the physical scenario, including not only human-robot conditions but also environment changes. However, the appearance of unpredictable events may cause an inconsistency between the established schedule and actual execution. To cope with this issue, an environment-adaptive assignment method based on digital twin for human-robot collaboration is formed in this study. The proposed approach is consisted of a factor-event-act mechanism that analyzes the dynamic events and their impacts from both internal and external perspectives of the digital twin, and a GA-based assignment algorithm to response to them. Experiments are carried out in the last part, aiming to show the feasibility of the proposed method.
