Summary: Human-robot collaborative assembly combines human flexibility and robot efficiency in mass personalization production. To improve robot's cognitive ability, this research proposes a two-stage skeleton-RGB integrated model for recognizing highly similar human actions, an online prediction approach for predicting human actions ahead of schedule, and a dynamic response scheme for accurate part positioning and continuous update of human actions. Experimental results demonstrate the effectiveness of the proposed model and approach in achieving precise human action recognition and online prediction with lower computational cost.

Summary: This article proposes an end-to-end pipeline for synchronously regressing potential object poses from an unsegmented point cloud. It extracts point pair features and uses a voting architecture for instance feature extraction, along with a 3D heatmap for clustering votes and generating center seeds. An attention voting module is also employed to adaptively fuse point-wise features into instance-wise features. The network demonstrates robustness and improved performance in pose estimation.

Summary: With the increasing demand for product customization, the capacity of traditional production lines is facing new challenges. The traditional monitoring system is unable to meet the information interaction requirements between the factory management level and the executive level due to information redundancy and complex production process. To address this gap, a novel mobile production monitoring system (AIMPMs) with human-in-the-loop control is proposed, leveraging cutting-edge AR and indoor positioning technique. The proposed system utilizes UWB and IMU fusion indoor positioning technology for accurate indoor positioning information, and includes a lightweight indoor map and a nearest-neighbor decision algorithm for virtual monitoring.

Summary: Future manufacturing will witness a shift towards collaboration and compassion in human-robot relationships. To enable seamless knowledge transfer, a unified knowledge representation system that can be shared by humans and robots is essential. The Human-Robot Shared Assembly Taxonomy (HR-SAT) proposed in this study allows comprehensive assembly tasks to be represented as a knowledge graph that is understandable by both humans and robots. HR-SAT incorporates rich assembly information and has diverse applications in process planning, quality checking, and human-robot collaboration.

Summary: This paper addresses the problem of nonfragile state estimation for semi-Markovian switching complex-valued networks with time-varying delay. By constructing an event-triggered generator and solving matrix inequalities, less conservative criteria are obtained, and the gains of the nonfragile estimator are explicitly designed. A numerical example is provided to demonstrate the effectiveness of the proposed estimation scheme.
