Novel Motion Control System for Industrial Robot Arms Enhanced by Innovative Method and PLC Integration

Abstract

Industrial robotic arms are versatile equipment designed for complex tasks and operations, and they hold significant potential in industrial production. However, traditional robotic arm automation faces several challenges, including limited motion accuracy, slow response speed, large physical footprint, and insufficient flexibility, resulting in potential safety hazards. Programmable Logic Controller (PLC) offers remarkable advantages in industrial control such as flexible operating features, precise control capabilities, and superior performance. PLC stands out as a highly suitable solution for industrial control applications. Therefore, this paper proposes an innovative integration of PLC and robotic arms to develop a motion control system that effectively enhances the accuracy, flexibility, and safety of robotic arms applied for industrial transportation production lines. The developed control system is innovatively based on the integrated features and logic control characteristics of the PLC, and utilizes the rotation of the robotic arm and the clamping capability of the pneumatic gripper to automate material transport between production lines to meet more complex control requirements. The human-machine interaction, detection, drive, and pneumatic modules are uniformly commanded. The system achieves orderly and collaborative operation among these modules, enabling flexible motion control of the robotic arm and efficient material grasping in complex environments. Through simulation, the characteristics of the control system is analyzed and discussed. The results demonstrate a relatively flexible grasping effect, providing valuable insights for intelligent industrial production lines.
