Smart Visitors Guidance Robot for Hospital Environments

Abstract— This paper presents a smart patient monitoring and alert system designed to enhance safety and responsiveness in healthcare environments, particularly for elderly and mobility-impaired individuals. The system integrates obstacle detection, real-time health monitoring, smart navigation, and emergency alert features into a compact, Arduino-based platform using the ATmega328 microcontroller. Key health parameters are monitored continuously, and any abnormal values automatically trigger an emergency alert through a buzzer. The buzzer also supports manual activation by the patient in critical situations. Obstacle sensors assist with navigation in indoor environments, helping avoid collisions and ensuring smooth movement. Real-time monitoring ensures that healthcare personnel or caregivers can respond quickly to emergencies.
