        abstract = {In hospitals, transportation hubs, and educational campuses, service robotics has advanced from controlled industrial environments to public-facing human-centric applications. This work presents HARI (Human Assistance Robotic Interface), a multi-functional mobile robotic platform designed to assist navigation, interaction, and service delivery within university campuses. The system integrates facial recognition, touch-screen-based interaction, autonomous line-following navigation, and localized data services into a unified architecture. Computing is distributed between a Raspberry Pi 4B for high-level AI and GUI processing and an Arduino Mega 2560 for deterministic real-time motor and sensor control, communicating over USB Serial. The navigation subsystem employs PID-controlled lines following augmented with the LSRB decision algorithm and RFID-based positional checkpoints, achieving a lateral deviation below ±2 cm. Face recognition achieves 90–95% accuracy using a dib 128-dimension encoding pipeline. Delivery trials over 40 runs yielded a 95% task-completion rate. Fiber composite panels reduce chassis weight while maintaining structural integrity, keeping total fabrication cost low. Experimental results confirm stable, reliable performance across all core functions, establishing HARI as a scalable, modular, and economically viable solution for smart-campus deployment.},
