Autonomous Library Assistant

This project presents the design and development of an Autonomous Library Assistant Robot designed to help disabled people locate book sections inside a library. In large libraries, physically searching for books is difficult for people with disabilities and can take a long time without assistance. The proposed system uses an ESP32 microcontroller with WiFi communication to receive commands from a web-based interface developed using HTML. The robot moves using two 12V planetary gear motors controlled by BTS7960 motor drivers and follows predefined paths using a 5-channel IR sensor array. The user selects the required subject from the web application running on Raspberry Pi, and the robot moves forward to guide the user to the desired section. This system reduces manual effort, improves accessibility, and demonstrates the use of robotics in assistive and smart library automation.
