Introduction

I. INTRODUCTION

To address the need for continuous supervision and real-time feedback on an infant's well-being, baby monitoring systems have been developed. These systems utilize a combination of sensors, cameras, communication technologies, and advanced algorithms to capture and analyse data related to the baby's activities. The primary objective of a baby monitoring system is to provide parents or caregivers with peace of mind by enabling remote monitoring and tracking of various aspects of the infant's safety and environment. One of the key challenges faced by parents and caregivers is ensuring the baby's safety and well-being during periods when they need to attend to other responsibilities or when infants are sleeping. A baby monitoring system acts as a technological solution that addresses this challenge. By continuously monitoring the baby's sleep patterns, movements, position, and even vital signs, these systems provide real-time feedback and alerts to parents or caregivers. The benefits of a baby monitoring system are manifold. Firstly, it allows caregivers to detect and respond promptly to potential risks or needs. For example, the system can alert caregivers if the baby rolls over to an unsafe position, leaves the crib, or experiences discomfort. By providing this level of supervision, the system ensures that the baby remains in a safe and comfortable environment. Furthermore, baby monitoring systems contribute to the early detection of potential health issues or abnormalities. By continuously monitoring vital signs or unusual behaviours, caregivers can identify patterns or changes that may require medical attention. This early detection enables timely intervention and promotes the overall health and well-being of the infant.

II. RELATED WORK

Different technologies have been there for the autonomous drone the below table shows the previous works and technologies implemented on this autonomous drone 

  1. The research paper titled "A Low-Cost Wet Diaper Detector Based on Smartphone and BLE Sensor" by MD Saifur Rahman, Chulhyung Choi, Young-pil Kim, Sikyung Kim, and Jungwan Choi (2017) addresses the importance of wet diaper detection for individuals with severe retardation or dementia. It highlights the negative consequences of wet diapers, such as rashes and infections, and the need for continuous monitoring. Existing wet diaper detection systems and sensors are often expensive and complex. Therefore, the authors propose a low-cost smart care system that utilizes a smartphone and Bluetooth Low Energy (BLE) transmitter for wet diaper detection. The system incorporates flexible conductors placed in the most urine absorption area of the diaper. When the diaper becomes wet, the resistance between the two terminals connected with the conductors decreases.
  2. This decrease in resistance triggers the BLE transmitter to send a warning alarm to a smartphone application, causing the phone to ring. The paper focuses on the integration of BLE technology, a smartphone, and a wet detector system using components such as the nRF51288 and an NPN transistor. By utilizing these low-cost and easily accessible technologies, the proposed system offers a cost-effective solution for wet diaper detection.
  3. In the research paper titled "An Automated Baby Monitoring System" by Y. Sai Subhash Reddy, Koye Sai Vishnu Vamsi, Golla Akhila, Anudeep Poonati, and Koye Jayanth, the authors address the challenges faced by working parents who are unable to physically care for their infants due to geographical distance. The paper proposes a framework for infant monitoring that utilizes computer vision techniques and sensor data analysis. The framework leverages a Convolutional Neural Network (CNN) to predict the baby's position and detect their movements. It also focuses on identifying specific sounds, particularly crying, to enable parents to assess the baby's condition remotely. The Raspberry Pi is utilized as the central processing unit, continuously processing data from various sensors. The system incorporates a camera module to capture video streams and images of the baby, ensuring constant monitoring. The proposed system aims to monitor the baby's temperature and crying status. The Raspberry Pi B module manages all the connected devices, including IoT modules for capturing videos or photos during abnormal conditions. Sound sensors are employed to recognize the baby's cries, temperature sensors determine the infant's body temperature, and Pi cameras capture the baby's surroundings. These captured data and images can be sent to guardians or parents over the internet. Overall, the authors suggest that the proposed system offers a simplified and convenient solution for busy parents to monitor their infants remotely. By utilizing computer vision techniques, sensor data analysis, and IoT capabilities, the system enables parents to effectively manage and care for their infants even when physically separated from them.
  4. In the research paper titled "An Intelligent Baby Monitor with Automatic Sleeping Posture Detection and Notification" by Tareq Khan, AI and image processing techniques were utilized to develop a baby monitoring device that can automatically recognize potentially unsafe situations. The device was designed to detect various conditions, including whether the baby's face was covered while sleeping on the stomach, if the baby had thrown off the blanket, if the baby was frequently moving, or if the baby's eyes were open due to awakening. When any of these situations occurred, the monitoring device would send notifications and alerts to the caregiver's smartphone, eliminating the need for constant monitoring. Instead, caregivers would be notified only when their attention was required, providing them with peace of mind. The device was implemented using NVIDIA's Jetson Nano microcontroller, which integrated a night vision camera and Wi-Fi connectivity. Deep learning models were developed and deployed on the microcontroller for pose detection, face recognition, and landmark detection. These models enabled the device to accurately analyze the baby's sleeping posture and detect any potentially risky situations. A prototype of the monitoring device and a corresponding smartphone app were successfully developed and tested under various scenarios. The results demonstrated the effectiveness of the device in automatically detecting and notifying caregivers about unwanted situations, providing an added layer of assurance compared to traditional baby monitors.

  6. In the research paper titled "Smart Infant-Monitoring System with Machine Learning Model to Detect Physiological Activities and Ambient Conditions" authored by Samira Shamsir, Omiya Hassan, and Syed K. Islam, the authors present the development of an intelligent monitoring system for infants. This system utilizes multiple non-invasive sensors to detect various physiological activities including respiration, movement, noise, and position, as well as ambient temperature and humidity. By collecting and processing data from the different sensor modules, the smart infant monitoring system can generate alarm signals in the event of adverse situations such as apnea, seizures, or uncomfortable environmental conditions. The integration of machine learning models enables the system to analyze the acquired data and identify patterns or anomalies associated with critical events.

The use of non-invasive sensors in this system ensures a safe and comfortable monitoring experience for infants, as it eliminates the need for invasive procedures. Additionally, by considering ambient conditions such as temperature and humidity, the system provides a comprehensive monitoring solution that takes into account the overall well-being of the infant. Overall, the presented research highlights the significance of developing smart infant monitoring systems that combine non-invasive sensors and machine learning techniques. Such systems have the potential to improve infant care and provide caregivers with timely alerts for prompt intervention during critical situations.
