ABSTRACT
The development of autonomous systems designed primarily for the detection and suppression of flames has seen a considerable increase in attention in the modern technological environment. The creation of a mobile robot that can be remotely controlled is the innovative approach suggested in this paper for addressing this challenge. The main objective of this research project is to create an adaptable robot by combining the flexible Arduino Uno development platform with the user-friendly LabVIEW graphical programming environment.
Operational capabilities of the robot include a wide range of complex tasks that are necessary for efficiently assisting firefighting activities. It is capable of autonomous navigation, assuring secure movement by carefully avoiding hazards in its way. It also has sophisticated fire detection systems that allow it to quickly detect the existence of a fire. Additionally, it shows proficiency in estimating the distance to the closest obstruction, an essential skill that raises the total operating safety and effectiveness.
Bluetooth technology is used to construct the communication infrastructure that connects the robot to the LabVIEW interface, enabling a smooth method of remote control and real-time monitoring. This paper adds considerably to the development of cutting-edge solutions for fire detection and extinguishment in challenging and complex environments by extensively examining the design, implementation, and performance of the robot.

I.INTRODUCTION
The development of autonomous, self-sufficient robots with the ability to perform tasks lowers the need for human intervention and is an essential objective in the area of robotics. These robots will be controlled by a computer system and equipped with environmental sensors [3]. Being able to walk around on its own defines a mobile robot, which falls under the general heading of mobile robotics, a branch of robotics and information engineering. These machines belong under the category of autonomous mobile robots (AMR), which refers to machines that can move around freely without the need of physical or electromagnetic directing aids. As an alternative, some mobile robots utilize guidance systems to travel specified paths inside of restricted environments.
The Arduino Uno development board, acting as a processing platform holding thirteen digital inputs/outputs, six analog inputs, and a serial port for peripheral interface, are the fundamental components required for this technological activity. It also has a USB port that makes user interaction easier [2].
– HC-SR04 Ultrasonic Sensor, which provides a practical way to measure the separations between still or moving objects. It touts Arduino compatibility and offers benefits including the use of digital I/O pins, increased noise immunity, and improved accuracy [5].
– LM393 IR Flame Sensor Module, which can detect light sources with wavelengths ranging from 760 nm to 1100 nm and is responsive to both flames and regular light. It interfaces directly with the microcontroller IO port.
A user-friendly Bluetooth SPP (Serial Port Protocol) module precisely created for the quick installation of wireless serial connections is the HC-05 Bluetooth Module.
– L298N Motor Driver is a control device that uses an H-Bridge design to enable simple direction and speed control for up to 2 DC motors.
SG90 Servo Motors are widely utilized in robotics and other applications because of their controllable rotating capabilities. This servo motor has a 180-degree rotation angle and is appropriate for low-power applications.
– H-Bridge L9110s for DC motor are ideal for jobs requiring control of the speed and direction of DC motors.
– DC motor with a 1:48 gear ratio that is ideal to construct mobile robots owing to its wide working voltage range of 3V to 6V and its simple wheel connection.
– A submersible pump that can be integrated with circuit boards, modules, and sensors is the 3-6V Water Pump.
