Line Follower Cart Manufacturing Line

Abstract

This project aims to develop and analyze a line-following cart assembly system using the Discrete Event Systems (DES) approach. The system encompasses three main stages: a cutting station, where a robot performs the cutting of parts; an assembly station, where the operator adds the battery, Arduino, and two line sensors to the cart; and a coding station, where another operator programs the microcontroller. The primary challenge in automation and modeling is ensuring the synchronization of these stages, eliminating bottlenecks in the production flow, and ensuring operational efficiency. The system inputs include the robot command at the cutting station, the manual input of components at the assembly station, and the code entered by the operator at the final station. The outputs include the states of the actuators responsible for cutting, assembling, and finalizing the cart. To model the assembly process, Petri Nets were used, allowing the analysis of the system's dynamic behavior, and Sequential Functional Programming (SFP) was employed to structure the control logic and ensure the synchronization of operations. The analysis of the assembly process model provides insights into the stages of the process, enabling the study of how the assembly process is modeled. The results obtained demonstrate that the application of DES methodologies enabled a detailed analysis of the assembly process and allowed the implementation of a reliable and efficient system. The project's impact includes optimizing the production process, reducing idle times, and improving the final product's quality. The development reinforces the use of DES in industrial applications, contributing to advances in automation and control.
