The term Industry 4.0 indicates the fourth industrial revolution. It consists of a production and business management model based on the interconnection between physical and digital devices. In particular, the manufacturing sector is experiencing a new era of development powered by a series of emerging high technologies such as human-robot collaboration, the Industrial Internet of Things (IIoT), cyber-physical systems, augmented reality, machine learning, and artificial intelligence. These features are necessary to analyse, interpret, and predict the real behaviour of machines and devices used in the manufacturing sector, such as autonomous robots and automated guided vehicles (AGVs). One of the main benefits of the digital transition driven by Industry 4.0 is the real-time accessibility of comprehensive information from devices involved in the manufacturing processes, acquired by integrated sensors embedded in the machines and camera systems that monitor the shop floor, and transmitted through the internet network.
