        abstract = {The rapid expansion of educational infrastructure has made navigating sprawling college campuses increasingly difficult for visitors, new students, and guests, necessitating the development of an autonomous or semi-autonomous navigational aid. This project presents the design and implementation of a Robotic Guide for College Visiting People, a cost-effective and efficient solution built upon the versatile ESP32 microcontroller. The primary objective of this system is to bridge the gap between human inquiry and spatial orientation by providing a localized, interactive guide. The robot’s hardware architecture integrates a robust power supply system to ensure longevity during operation, an LCD display for real-time visual feedback and status updates, and a Bluetooth module for seamless wireless communication. Central to the user experience is a custom-developed mobile application, which serves as the primary interface for visitors to input their desired destinations, such as administrative offices, laboratories, or lecture halls. By leveraging the dual-core processing capabilities and integrated Wi-Fi/Bluetooth features of the ESP32, the robot processes commands from the smartphone app and translates them into precise motor movements. The LCD display enhances accessibility by showing the robot’s current state, destination names, or welcoming messages, ensuring a user-friendly interaction for those unfamiliar with the campus layout. The methodology focuses on a modular design approach, allowing for scalability; additional sensors like ultrasonic or infrared can be integrated for obstacle avoidance to ensure safe passage through crowded corridors. During testing, the system demonstrated high responsiveness to Bluetooth commands and provided accurate directional guidance, significantly reducing the "search time" for visitors. This project not only showcases the practical application of Internet of Things (IoT) technologies in service robotics but also provides a template for smart campus initiatives aiming to improve institutional hospitality and operational efficiency. By replacing traditional static maps with a dynamic, mobile guide, this system offers an innovative, tech-forward approach to indoor and outdoor campus navigation, ultimately fostering a more inclusive and navigable environment for all stakeholders.},
