Abstract
This project presents the integration of a robotic cell with a vision system, composed of a KUKA industrial robot, a PLC designated as the process master, and an industrial camera. The focus is on the development of the integration along with the programming logic involved, highlighting how Ladder language in the PLC and KRL in the robot can be structured to ensure synchronization and efficiency. The project demonstrates the organization of the logical flow in the PLC, which is responsible for coordinating the cell, and the mutual communication between the devices. The types of exchanged signals, communication protocols used, and how commands are transmitted, processed, and executed are explored. In this way, the study aims to demonstrate how the PLC acts as the control center, commanding the interaction among the cell’s devices. The results discussed show that using the PLC as the master provides greater flexibility in the process and facilitates logic adjustments without the need to reprogram the robot for every variation. This logical integration, combined with the vision system, enhances the robustness and scalability of applications for Industry 4.0.
