This study addresses the integration of YOLOv8 and ArUco Markers to improve screw detection and measurement. The main objective is to develop a solution that will allow the identification and measurement of screws accurately using computer vision. The methodology involves using a webcam to capture images, where the YOLO algorithm performs object detection, and ArUco Markers are used to calculate screw dimensions. The system was implemented to capture and save images of objects, in addition to recording measurements in a spreadsheet. The research was carried out in a controlled environment, focusing on systems integration. The results improved the system's efficiency in identifying and measuring screws in an automated and precise way, showing that the combination of computer vision techniques can increase the capacity of robotic systems in object manipulation and inspection tasks, being viable in industrial inspection processes. and quality control.

Maintenance is crucial for companies that have operating equipment and machinery. Its purpose is to keep these assets in good condition, extend their lifespan, reduce unplanned downtime, and enhance worker safety. Inadequate maintenance can lead to decreased productivity, increased repair costs, compromised worker safety, and diminished product quality. Well-planned and executed maintenance brings benefits such as cost reduction, increased machine availability, improved product quality, enhanced efficiency, and reduced workplace accidents. It is a strategic tool for company competitiveness, ensuring the continuity of production processes and customer satisfaction. This work presents the concept of maintenance and the philosophy of TPM (Total Productive Maintenance), also known as Total Productive Management. Through a case study, it demonstrates its results in addressing the identified problems and highlights the importance gained from the beginning of its implementation in the process, along with the significant role of the tools that supported the methodology's implementation. The information was obtained through exploratory research, document analysis, and interviews with the individuals involved.
