IoT Based Medical Assist Robot for Patient Monitoring (Smart Nurse)

IoT Based Medical Assist Robot for Patient Monitoring (Smart Nurse)

Project Overview

The IoT Based Medical Assist Robot for Patient Monitoring, also known as Smart Nurse, is an intelligent healthcare support system designed to assist medical staff by continuously monitoring patient health parameters and providing real-time data access remotely. The system aims to reduce the workload of nurses and doctors while improving patient care, safety, and response time.

This project integrates IoT technology, biomedical sensors, embedded systems, and wireless communication to monitor vital signs such as heart rate, body temperature, oxygen level, and patient status. All collected data is transmitted to a cloud dashboard for real-time monitoring.

Objective of the System

• To continuously monitor patient vital signs

• To assist nurses and healthcare staff remotely

• To reduce direct physical contact when unnecessary

• To provide real-time health data using IoT

• To improve efficiency in hospitals and care centers

Working Principle

1. Biomedical sensors attached to the patient measure vital health parameters.

2. Sensor data is collected by a microcontroller (Arduino / ESP / Raspberry Pi).

3. The data is processed and displayed locally on an LCD screen mounted on the robot.

4. Using an IoT platform, the data is transmitted wirelessly to a cloud dashboard.

5. Doctors and nurses can monitor patient conditions remotely via laptop or mobile.

6. If abnormal readings are detected, alerts can be generated for immediate attention.
