A new review published in the International Journal of Production Research explores how manufacturers can make human-robot collaboration safer, more adaptive and efficient by improving the way robots predict human behavior in shared industrial environments.

As manufacturing moves toward Industry 5.0, production systems are becoming more human-centerd, combining human creativity, judgement and dexterity with robotic precision, strength and speed.
But as people and robots work more closely together, new safety and coordination challenges emerge. If robots cannot accurately anticipate what a worker will do next, the risk of collisions, delays and inefficient collaboration increases.
The review examines the major approaches used to predict human behavior in human-robot collaboration, including mechanism-based models built around physical motion and interaction rules, data-driven models that learn from sensors and artificial intelligence, and hybrid approaches that combine both.
The researchers show that while each method has strengths, more integrated approaches are likely to be the most effective for future human-centric manufacturing systems.
The paper also points out several key challenges that require attention including variability of human behavior, the absence of standardized multimodal datasets, the limited scope of physical world models, and the need to more effectively consider human trust, workload, and cognitive state during collaboration.
To address these gaps, the authors propose a unified framework that integrates multimodal data, physical world modelling, behavior prediction, and adaptive control.
Co-author Yunlong Tang, Assistant Director of the Monash Centre for Additive Manufacturing, and Senior Lecturer in Mechanical and Aerospace Engineering and Materials Science and Engineering, said improving how robots interpret and respond to human behavior will be essential for the next generation of manufacturing systems.
“Industry 5.0 is about designing manufacturing systems around people as well as technology. By improving how robots predict human behavior, we can move towards production environments that are not only more productive, but also safer, more adaptive and more human-centerd,” Mr Tang said.
The review suggests that future progress will depend on combining physical models, sensor data and AI in ways that allow robots to respond more intelligently to human movement, intent and changing working conditions.
The research highlights how more intelligent prediction and planning tools could help manufacturers improve safety, strengthen collaboration between workers and robots, and build production systems that are more resilient, efficient and responsive.
As Industry 5.0 continues to evolve, these kinds of human-centerd approaches are expected to play an important role in shaping the future of advanced manufacturing.
