Automatic Library Book Picker

Automatic Library Book Picker is an ambitious project that aims at digitizing and automating libraries by incorporating the power of robotics, automation, and IoT technologies. This project also aims to promote a new age of technology to innovate the age-old invention of libraries. A NodeMCU serves as the core control unit for this automated library book picker, utilizing its built-in WiFi connectivity and Arduino compatibility to provide smooth control and communication. It uses pulse width modulated (PWM) signals to send information to other components. The four wheels are controlled by L298N motor drivers, which allow the robot to move in the library. Furthermore, the system incorporates a 60 RPM side-shaft DC motor to enable arm lifting operations, and a servo motor governs the functioning of a robotic gripper mechanism necessary for book manipulation. Thus, by converging these components, technologies, and advanced control algorithms, the automatic library book picker performs tasks such as retrieving books from the shelves with minimal human effort, providing security to the books in the library by reducing human contact, and also improving the user experience.
