Summary: With the development of manufacturing industry towards personalization and flexibility, a human-robot collaboration system based on Electromyography (EMG) signals is proposed to enable the robot to understand human motion intention and play the guidance role of human tutor. The system improves the recognition accuracy of motion intention through modifying the Fast Orthogonal Search (FOS) algorithm and introduces evaluation methods from the perspective of ergonomics to balance tracking accuracy and collaboration comfort. The end-to-end collaborative control model based on Deep Deterministic Policy Gradient (DDPG) reinforcement learning algorithm effectively saves physical power for the human tutor and exhibits good coordination between accurate tracking and comfortable collaboration.

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 article proposes a cooperative game-based approximate optimal control method for human-robot collaboration (HRC)-oriented modular robot manipulators (MRMs). The human motion intention estimation is developed using robot position measurements based on a harmonic drive compliance model. By employing the cooperative differential game strategy, the optimal control problem of HRC-oriented MRM systems is transformed into a cooperative game problem. The experiment results demonstrate the advantage of the proposed method.
