Design and Implementation of a Hospital Assistant Robot for Smart Healthcare Automation using AI Technology

Abstract - The integration of Artificial Intelligence (AI), IoT, and autonomous robotics enables smart healthcare automation in modern hospitals facing high patient loads and staff shortages. This paper presents a Hospital Assistant Robot (HAR) integrated with a Hospital Management System (HMS) to automate tasks such as medicine delivery, patient interaction, and indoor navigation. The system uses odometry-based localization and PID-controlled navigation for reliable movement, along with a speech-to-text, LLM, and text-to-speech pipeline for voice interaction. MQTT ensures secure, real-time communication between the robot and HMS. Experimental results demonstrate accurate navigation, reduced task time, and improved operational efficiency, validating its suitability for scalable healthcare deployment.
