Abstract

This paper presents an experimental study on the PID algorithm applied to a vehicle system that maintains a fixed distance from an object. The research focuses on how changes in PID parameters affect the vehicle's behavior. The system comprises an SRF05 ultrasonic sensor connected to an Arduino, controlling the vehicle is forward and backward movements to follow the object. Through a series of experiments, analyses, and evaluations, the study explores the effectiveness of the PID controller and addresses challenges. The results help identify the optimal PID parameter values for the system systematically.

Abstract

The rapid development of automation and robotics has increased the demand for high-performance industrial systems, in which Delta robots play a crucial role due to their lightweight structure, high speed, and precise positioning capability. This study aims to design, implement, and evaluate a Delta robot-based product classification system integrating PLC S7-1200 control and Machine vision. The proposed system employs a camera to detect object shape, color, and position on a conveyor, while a PC processes the image data and computes the robot’s inverse kinematics before transmitting control commands to the PLC. A hardware model of the Delta robot was designed and fabricated, and a dual-mode control application was developed to monitor and operate the robot in real time. Experimental results demonstrate that the system achieves stable operation, with a classification speed of up to 20 products per minute and an accuracy of approximately 95.7% for picking and placing tasks. The findings confirm the feasibility and effectiveness of integrating vision-based detection with high-speed parallel robot control for industrial sorting applications. The study also provides a foundation for further optimization in processing speed, mechanical design, and advanced image-processing techniques to enhance system performance in practical manufacturing environments.
