Automatic Ergonomic Postural Risk Monitoring on the Factory Shopfloor ‒the Ergosentinel Tool

The enabling technologies of the Industry 4.0 program can support the smart factory of the future to face the challenges related to their sustainable growth. In particular, given the progressive ageing of the population, it is mandatory to develop systems able to preserve operators’ wellbeing and to prevent the incidence of work-related musculoskeletal disorders. By exploiting a recently introduced low-cost sensor we developed and validated a reliable prototype for automatic assessment of ergonomic postural risk in the factory shopfloor. Encouraged by the results of the validation process, we enhanced the prototype functionalities. The tool will serve both as a monitoring system for the evaluation of postural risk and a training system for increasing operators’ awareness. In this paper, we describe the design of the prototype and the enhanced functionalities of the final version, ‒ the ErgoSentinel.
