Controle orientado a eventos de uma fábrica inteligente com base em realimentação visual e uma estrutura de programação distribuída.

Abstract

The digital transformation driven by Industry 4.0 establishes a new industrial conĄguration, characterized by the presence of intelligent automation. In this context, smart factories emerge as connected, autonomous, and adaptive production environments capable of adjusting processes in real time to respond to dynamic manufacturing conditions. This work presents the development of an event-driven control system for a smart factory, utilizing visual feedback and a distributed programming structure with the Robot Operating System (ROS). The system was designed to capture and process visual data using a Kinect camera and ArUco Ąducial markers for validation, aiming to provide adaptive and efficient automation within the Smart Factory laboratory at the Federal University of Campina Grande (UFCG), which is equipped to replicate smart factory activities in a controlled environment. The implemented architecture includes an event-based model for controlling image acquisition devices, as well as the integration of a behavior tree to manage camera operations and monitor marker positions within the environment. Simulation and testing conducted at the Smart Factory conĄrmed the systemŠs ability to respond to visual events, promoting the Ćexible automation required in the context of Industry 4.0.
