This paper presents the implementation of a fully automated library system designed to enhance the efficiency of book retrieval and storage. The system uses a Programmable Logic Controller (PLC) to control the robotic vehicle with sensors and actuators. The user interface consists of a keypad and LCD, allowing users to select books by entering their codes. The robotic vehicle then locates and delivers the requested books, reducing search time significantly. Additionally, the system provides automated book storage and is capable of indicating book availability. The project aims to demonstrate the integration of mechatronics systems in practical applications, reducing human effort and increasing customer satisfaction through automation. The system also features a data sheet with book codes, enabling users to easily find and request books. The robotic vehicle's ability to navigate and retrieve books is a key aspect of the system's design, ensuring a seamless and user-friendly experience. This smart library system demonstrates how technology can revolutionize library services, giving us a peek at the future of automated information retrieval in public spaces.
