Real Time Implementation of Virtual Doctor with Generic Medicine Dispensing Box

Abstract—This paper presents the development of a robot- based medical assistant designed to monitor patients using Inter- net of Things (IoT) technologies and automated medicine dispens- ing capabilities. The system forms the basis of a virtual doctor robot, enabling healthcare professionals to interact with patients remotely, especially in unfamiliar or high-risk environments such as quarantine zones or isolation wards. The proposed system integrates an Arduino-based controller with RFID authentication, real-time clock scheduling, automated dispensing mechanisms, and IoT communication modules (WiFi and GSM). The robot enables contactless monitoring, reduces unnecessary patient- doctor interaction, and ensures accurate, timely medication delivery through sensor-verified dispensing. Preliminary testing demonstrates reliable data transmission, accurate QR scanning, and stable wireless connectivity, making the system suitable for hospitals, emergency healthcare setups, and quarantine centers where minimal physical contact is crucial.
