Human-Robot Interaction (HRI) and Collaborative Robotics (Cobots) for Next-Gen Intelligent Manufacturing, Service Automation, and Human-Centric Cyber-Physical Workspaces: A Comprehensive Review

Abstract

Human–Robot Interaction (HRI) and Collaborative Robotics (Cobots) are rapidly transforming industrial environments, service sectors, smart healthcare, domestic assistance, and human-centric cyber-physical systems. Unlike traditional robots that operate in isolated zones, cobots are designed to work safely and adaptively alongside humans, enabling shared workspaces and distributed intelligence. This paper provides a detailed overview of HRI concepts, interaction models, cognitive frameworks, collaborative task design, safety mechanisms, and real-world applications. It further analyzes trends such as emotion-aware robots, intent prediction, adaptive autonomy, explainable AI based robotic behavior, and multimodal interfaces. The challenges, limitations, and future research directions are also discussed, emphasizing the importance of trust, safety, transparency, shared control, and ethical considerations. The review highlights how future cobots will evolve from simple assistive machines to intelligent partners capable of learning, reasoning, and collaborating seamlessly with humans.
