DESIGN AND DEVELOPMENT OF FIRE BOT

Abstract

Detecting and extinguishing fire are dangerous jobs for a fire extinguisher and often endanger the life of that person . This project is tasked with providing an engineering solution to this problem. A robot is a mechanical design capable of automatically performing a complex series of actions, especially one programmable by a computer. The robot's hardware includes a collection of several. sensors; smoke detectors,. temperature sensors, and gas sensors that provide the means to detect the risk of fire in the environment. Each of the sensors will continuously monitor the surrounding environment and send data to the Arduino controller in real time on surrounding conditions. The Arduino controller will use that information from the sensors and intelligent algorithms to determine if a fire is present. When a fire is detected, the robot will engage its actuation system with the motors and chemical based extinguisher which will transport the robot to the source of the fire in an efficient manner enabled by wheels or tracks to allow for movement over all terrains. Upon arrival at the ignition point, the pandemic robot will deploy its extinguishing capability. The chemical based chemical will be engaged by an Arduino based activation system using ABC powder and will immediately suppress the fire and risk of further damage.

BACKGROUND OF THE INVENTION
Fires are an age-old and devastating threat where, every year, many lives and property are lost in major fires. The traditional method of firefighting requires human intervention directly risking firefighters to perils such as bums, inhaling smoke, and collapse of structures. These risks are even stronger in powerful fires or areas that are inaccessible where a swift response is necessary to reduce damages. Despite the very best the firefighters can do, the chaotic and unpredictable nature of fire often hampers the human response.
Recent developments in robotics, sensor technology, and wireless communication have opened new avenues for the upgrading of fire detection and suppression capabilities. Firefighting robotic systems are designed specifically to operate in scenarios deemed too hazardous for humans to access, thereby minimizing the risk of personnel injury or death. Current solutions in the field of robotics for firefighting, though, still suffer from shortcomings regarding detection precision, response speed, and user control.


Most traditional firefighting robots rely on fixed sensor arrays and are defined by movements in the sequence that they are programmed. Such limitations may be responsible for efficiencies, especially during emergencies as every minute counts. Furthermore, systems seldom have an effective way of communicating the status of the fire or the operational parameters of the robot to the user, thus adding additional challenges in coordination of fire responses.
An integrated firefighting solution that seeks to have high sensing capabilities with autonomous navigation and control interfaces at hand will be sought after in order to face all these challenges. The flame sensors and temperature sensors measure specific wavelengths associated with flames and high-temperature environments, allowing for accurate fire detection by doing so. This information could then be processed by Arduino microcontrollers, which can make smart decisions regarding real-time data.
The present invention addresses the problems set out above in an integrated manner. A robot with both smoke, flame, and temperature sensors is used; such a robot will be able to sense potential fire hazards within the environment it covers continuously. The detection of a fire would allow the navigating, agile robot to reach the source thereof autonomously thus drastically cutting response time and improving safety.
Moreover, the proposed system uses Bluetooth-enabled mobile applications where users are also able to interact and control the robot in a remote view. "Bluetooth Terminal" is an intuitive interface which enables the management of movement as well as the firefighting of the robot either automatically or manually. Real-time communication is used for informed decisions, and the action of the robot is controlled according to the present fire situation.


But with the incorporation of Bluetooth, not only is there facilitation in the user's control, but also flexibility in the operations of the robot. Transmission of signals from the application to the Arduino microcontroller of the robot lets the user instantaneously know what the status of the robot and the conditions of the fire are. Two-way communication is essential for coordinating effective firefighting efforts, especially with complex scenarios that require
human oversight.

Developed to bridge the reality gap between advanced robotics and firefighting needs, this development produces a robot capable of independently detecting fires, navigating towards them, and then quenching them. The interface it provides for control and monitoring is user-friendly. This marks a significant milestone in fire safety technology because it combines both automation and user interaction. Novel solutions for that sector are important because its conventional approach has prevailed for a very long time.
In conclusion, within the complexity of the modem urban environment and constantly increasing frequency of fires, effective safe and independent firefighting solutions become of high demand. A current invention meets its essential advantage of a new approach in fire safety through robotics and smart technology by perfecting fire detection and suppression processes to finally realize the preservation of life and property.
OBJECTIVES

The detection can be done through smoke, flame, and temperature sensors. Further in this design, it will also use an Arduino microcontroller for enhanced navigation towards the fire source. It would use a chemical extinguishing mechanism for effective fire suppression and have a user-friendly mobile application for remote control and monitoring. Communication of this robot will take place with a fire station through seamless Bluetooth communication for direct information of fire conditions, thereby improving response times and generally efficiency in fighting.
SUMMARY
The developed invention is a completely independent firefighting robot capable of enhancing fire safety conditions through effective detection and extinguishing of fires with minimal loss to human life. It is equipped with smoke, flame, as well as temperature sensors that continuously monitor the environment for potential fire hazards in real time. The robot will be installed with an Arduino microcontroller. It will find out where the fire is arising on its


own; then, it will activate a chemical extinguishing mechanism to spread out the liquid and douse the flames. It will also come equipped with a user-friendly, remote control and monitoring mobile application for real-time fire updates using Bluetooth. This will ensure increased response time and overall effectiveness in firefighting efforts.

DETAILED DESCRIPTION OF THE INVENTION
The invention described herein is classified as an autonomous fire-fighting robot which is intended to detect and extinguish fires in unsafe areas, to serve as a safer and efficient option to a human firefighter. The system includes multiple sensors, microcontrollers and actuators, as well as wireless communication technologies, providing fire detection and location capabilities


in real-time modes, resulting in autonomous movement functionality and fire extinguishing ability as prerequisite actions following detection. The following gives an overall description of the major components and explains how the robot works.
1. Components of the Firefighting Robot:
a. Sensors: The robot has multiple sensors which will allow it to provide appropriate and complete fire detection functionalities. i. Flame Sensors: The flame sensor works by detecting infrared radiation emitted from flames. A flame will emit a specific wavelength at infrared levels and therefore can be detected
much quicker.
ii. Temperature Sensors: The temperature sensors utilize to monitor temperature changes of the ambient environment and provide an alarm of elevated temperatures associated"witfi"iire7 An alarm regarding the likelihood of fire would be reported if the temperature changes met predetermined levels.
iii. Smoke Detectors: Smoke detectors measure the concentration of smoke or particles indicating smoke. Having early detection of smoke indicates fire and thus allows for actions to extinguish the fire even prior to the flame being fully spread.
b. Microcontroller (Arduino UNO): The core component is that of the Arduino UNO microcontroller which compiles and processes the real-time sensor data to determine if there is a fire or not. The microcontroller uses pre-programmed algorithms to determine a fire through the inputs obtained from each of the sensors, then implements navigation to the identified source of fire, if necessary. The ATmega328 integrated circuit (IC) is identified as the main central processing unit within the Arduino component.
c. Mobility System: The robot has DC motors (one on each rear wheel) attached to a wheel or track system to allow it to pass through various terrains with ease. Based on sensor signals, the robot's design would ultimately allow it to be guided to independently navigate to the point

source of fire. Given then the designed specification of the fire-fighting robot's structure and

circuitry will allow for both actuation and motion of the fire-fighting robot to action a fire extinction process.
d. Extinguishing Mechanism: This specific fire extinguishing mechanism also operates from its own chemical extinguishing agent. Prior to detection of a fire, the robot's microcontroller sends a signal to activate the agent, which releases a concentrated jet stream of dry 111 ABC powder acting as the extinguishing agent to put out a fire consisting of Class A, B, and C fires.
The extinguishing mechanism also involves motors and actuators extending beyond the previously mentioned extinguishing agent components to extinguish the fire as quickly as
possible.
e. Wireless Communication (Bluetooth Module): The robot has a small Bluetooth module which would enable it to communicate to an external device such as an android mobile smart phone or mobile tablets. The Bluetooth module is wired to the Arduino UNO, therefore, the robot receives control signals from the user, and the user could receive status from the robot's sensors in a remote manner using the user's mobile device with the "Bluetooth Terminal" app. f. Mobile App: In addition, the robot can be controlled via a friendly user's view that has been integrated into an Android based app controlled by the user. The user could optionally have manual or automatic control of the robot's movement initiative and choose the specific extinguishing mode via controls in the app. The app interface would allow the user's group to view possible statuses of the sensors, alerts could be pushed to user smartphones upon fire detection, and remote control the extinguishing mechanism remotely.

2. Working Mechanism: The robot continuously tours the area looking for fire hazards with the help of flame, smoke and temperature sensors. Each sensor is separate and hands its output to the Arduino microcontroller, which at that moment does a real-time analysis of the data. Whenever one or several sensors indicate a potential fire threat, the microcontroller executes appropriate applied activities to analyze the data and locate the region and the size of the fire. Whenever the

measurable factors of the sensors exceed the predetermined values, the robot uses a specific algorithm to assess the degree of fire within the confines of its operational parameters, b.
Autonomous Navigation: Reacting to the detection of a fire occurrence, the system prompts the navigation sequence of the robot. After routing the relevant area, the robot follows the direction of the fire by creating its own path, based on the data obtained from the sensors. DC motors are used to turn the wheels or tracks and navigate on different terrains including changes of paths in the robot's effort not to block itself, c. Operation of Fire Extinguishing: As soon as the robot approaches the fire, its extinguishing system incorporates a chemical based liquid. ABC powder is then blasted in a targeted stream to further control the blaze. The fire extinguishing system is powered by a motor that is controlled based on the region of fire providing effective fire control measures, d. Control and Monitoring: The robot can be used in autonomous mode or manual mode, where the user maneuvers the robot to change direction and perform firefighting activities through the Bluetooth Terminal mobile app. This App has a controlling interface with some buttons that help to move the robot and use the spraying machine. The robot then becomes an autonomous machine that performs operations based on sensors.
