The main objective of this research is to analyze and optimize the control system of this robot through simulations to improve efficiency and production quality in the ceramic industry or other manufacturing sectors. The study consists of several stages, including a literature review to comprehend the concepts of the Falcon Millennium Robot, PLC Omron, and relevant theories in automation and robotics. Subsequently, problem identification is conducted to pinpoint areas that require analysis and optimization. The next step involves designing a Ladder Diagram using CX-Programmer software to control the automatic palletization process. Additionally, the control system's user interface (HMI) is designed using CX-Designer to facilitate the operator in controlling the system. Once the design is completed, simulations are conducted to verify the robot's performance and the palletization process before physical implementation. Experimental data is analyzed and collected in tables to measure efficiency, Conveyor 1 and Conveyor 2 speeds, and the time taken to transfer boxes to the warehouse. The analysis results show an average efficiency of approximately 88.5% in the automatic palletization process. Conveyor 1 and Conveyor 2 speeds increase gradually, and the average time taken to transfer boxes to the warehouse is around 41 seconds.
