FEMM Hub are pleased to announce that a new paper entitled ‘Applying a Fusion of Wearable Sensors and a Cognitive Inspired Architecture to Real-time Ergonomics Analysis of Manual Assembly Tasks‘ has been published in the Journal of Manufacturing Systems.

Many high value manufacturing systems still require ergonomically intensive manual activities which could expose workers to dangerous levels of ergonomically awkward positions which can lead to musculoskeletal conditions. This impacts productivity through lost days.

In this work, researchers in the Department of Automatic Control and Systems Engineering at the University of Sheffield propose a Cognitive Architecture for Wearable Sensors (CAWES); a wearable sensor system and cognitive architecture that is capable of taking data streams from multiple wearable sensors on a worker’s body and fusing them to enable digitisation, tracking and analysis of human ergonomics in real time on a shop floor. Furthermore, through tactile feedback, the architecture is able to inform workers in real time when ergonomics rules are broken. The architecture is validated through the use of an aerospace case study undertaken in laboratory conditions.
