Abstract

In healthcare contexts where human access is limited, particularly in isolation and quarantine rooms, autonomous solutions become critical. This study presents a novel solution to addressing this problem: a line-following robot built for use in hospital isolation units. The robot\'s operating principle is led by a color recognition system, which responds dynamically to certain colors linked with directing cues. The system\'s ability to capture vital information by utilizing the ESP32 camera module increases its utility beyond navigation, extending to the collection of patient vitals displayed beside beds. By combining precise navigation with information gathering capabilities, this line-following robot offers a potential solution for tasks in restricted access healthcare environments.

Introduction

I. INTRODUCTION

The increasing demand for novel approaches to tackle pressing issues in the field of contemporary healthcare has prompted the creation of autonomous technology. Hospital isolation zones provide a problem due to strict containment procedures that restrict human access in order to control the spread of illness. The necessity of ensuring patient care, keeping an eye on vital signs, and carrying out activities in these constrained circumstances has led to the investigation of robotics as a viable solution [1].

An autonomous line-following robot that is intended to traverse and function flawlessly in hospital isolation rooms is the innovative project that this research provides. The project, called "Robotic Guardians," seeks to open up new technological possibilities for disease prevention in healthcare environments. Robotic system integration, powered by sophisticated sensors and smart algorithms, presents a viable solution for jobs that typically require human participation but are limited by isolation zone safety and access restrictions.

The robot's advanced color recognition system forms the basis of its basic functioning. With the help of this technology, the robot may react dynamically to particular colors that are linked to directional indications and explore the isolating environment with accuracy. In addition, the addition of an ESP32 camera module expands the robot's usefulness beyond navigation by enabling it to gather and show critical medical data next to beds. As per the World Health Organization's member status report [3], the global healthcare infrastructure faces a significant shortage of medical professionals, with fewer than one physician available per one thousand people. Moreover, socioeconomic factors exacerbate the strain on healthcare systems, particularly in developing countries where poverty rates are high. The increased demand for medical services further burdens already overburdened healthcare facilities, leading to prolonged wait times, limited access to essential treatments, and escalated healthcare costs for patients. This research investigates the possibility of autonomous robots as invaluable allies in the ongoing war for disease management, since "Robotic Guardians" combine precise navigation with information gathering skills. This novel approach puts healthcare breakthroughs in locations with restricted access at the forefront since it can adapt to changing environmental cues while guaranteeing the safety of medical staff and patients.

II. LITERATURE REVIEW

Numerous significant advancements throughout this technology's history have prepared the way for the creation and application of these systems. The fundamental ideas and groundbreaking research, like that of Seymour Papert in the 1960s, have greatly influenced these robots. These early innovations were mostly concerned with building blocks, like control systems and sensor technology, which later became the essential foundations for more sophisticated uses[2].

The sensor technology that allows line-following robots to perceive and precisely follow predefined paths is a fundamental component of these robots [3]. A variety of sensors have been studied by researchers, such as infrared sensors, camera vision systems, and ultrasonic and LiDAR sensors, which have become more popular recently. The selection of sensors is frequently based on particular applications and environmental factors, and ongoing developments are increasing the robots' capacity for perception [8]. Control algorithms are crucial because they guide line-following robots along their intended paths. The majority of research has concentrated on the application of control techniques, including proportional-integral-derivative (PID) controllers, fuzzy logic, and machine learning-based approaches [4]. The goal of these algorithms is to maximize navigational efficiency and accuracy. Machine learning holds potential for intelligent and flexible path-following.

Line-following robots are becoming widely used in a wide range of sectors due to their adaptability. These robots assist in automated material handling and assembly procedures on production and assembly lines, which lowers human labor and related mistakes [5]. Line-following robots are very efficient in the logistics industry because they make inventory management and order fulfillment easier [6]. For precise operations like planting and harvesting in agriculture, which increase crop yields and optimize resource use, these robots are indispensable. These robots assist patients in finding their way around large medical facilities, which enhances patient experiences and lessens the labor of healthcare personnel [7]. Applications for security and surveillance have also made use of them to conduct regular patrols, strengthen security protocols, and increase surveillance capabilities.

Line-following robots have an effect that goes beyond increased production and efficiency. They have the capacity to preserve resources, lessen labor-intensive duties, and improve safety in a variety of settings [9]. Line-following robots have a great potential to optimize companies and enhance human welfare in a world where automation is becoming more and more important.

Despite enormous advancements, there are still problems with line-following robots. These challenges include issues with environmental adaption, scalability, and barrier avoidance. Novel methods to these difficulties are continually being researched, often making use of advances in machine learning, artificial intelligence, and sensing [10]. The ability to move adaptably and make decisions in real time in response to changing circumstances is the main focus of research efforts. It becomes evident that the development of a medical chatbot utilizing Artificial Intelligence (AI) stands as a promising approach to mitigate this crisis. By providing immediate access to medical information and facilitating appointments with specialists, such chatbots offer potential avenues for enhancing patient care and reducing mortality rates.
