Project Summary

Safety is more important than other things. So many established companies mainly focused on safety systems because a person life more precious than all other things. As the technology advances, the safety issues increased day by day. As we know that fire can create a big damage. Engineers are finding alternates of human work and finding new ways that can ease their work and save lives of humans. Fire extinguishing is a dangerous job so robots can be replaced by humans so that no harm can be done during the fire extinguishing process. Fire fighter robot is an equipment model which is used for extinguishing the fire. We have designed a controlled firefighting robot which could move through android application and also with internet connection. The firefighting robot can be controlled globally via internet and raspberry pi. A Wireless Wi-Fi camera is mounted on the robot for the monitoring and facilitation for the administrator. The administrator can see and move the robot accordingly. As we know that we need cloud for controlling devices through internet. So, we have used MQTT cayenne cloud to control the robot. The robot has the ability to control fire through water. The pump is mounted for creating the pressure. The robotic technologies have improved and are becoming an important part of our lives. This robot prototype can extinguish fire from the area where it is difficult for fire fighters to extinguish it. It can also explore the building while effectively finding fire. It can be operated from anyplace using mobile phone or a laptop. The robot uses sensors to detect the object and flames and move accordingly to the detected objects. Raspberry pi is the main brain of the project which processes the instruction and instructs the motor to move the robot in the desired direction, it also operate the water pump and spray water based on user commands. This robot is cost effective and open source system.

Project Objectives

Ever since the Almighty gave life to the mankind, it is constantly striving to get more efficient at what it does and where it is currently at. From the invention of the wheel, the first invention, to the modern hi-tech era this prime specie has advanced leaps and bounds where lifestyles have entirely changed and become incredibly easier to what it was at any time or era before. But in spite of all these mankind is unable to answer to the questions that the nature throws at it or other such unfortunate incidents and their ramifications can get seriously destructive in case of some disturbance in the normal motion that the environment is in, such as in the case of natural calamities for instance flash floods, earthquakes, wildfires etc. But the damage that these disasters cause can be controlled if not avoided altogether. One such way of controlling the damage is firefighting.

Fire fighter as a whole is high risking life threatening profession. Each year throughout the world a large number of fire fighters lose their lives during these operations. The number of such incidents may continue to increase if there is no improvement in firefighting techniques and the related technology. Therefore, the need for a technologically advanced firefighting robot arises, which can decrease these incidents and help improve efficiency especially when we talk about those extreme scenarios in which it becomes difficult for a human to move inside a building. Thus, we present our bit of work in which after rigorous research we were able to come up with a robot for extinguishing fire autonomously as well as through android application. In recent research, the development of technology on firefighting is in progress around the world. Most of the tools and equipment are manually operated by the fireman. In the new era of technology, the technology of firefighting machines is mostly conquered by the Western Countries.

Other objectives are as follow:

• Minimization of disastrous consequences
• It provides quick response to sudden eruption of fires in places such as houses                 
• It provides us greater efficiency to detect the flame.
• Receive real time video footages through wifi
• Reliable design
• Easy to control
• Economical

Project Implementation Method

The project implementation is based on many steps like first we need to select design the circuit diagram and then we need to design the simulation of the project. After simulation designing and testing the circuit on software, we will start test the circuit using the hardware like breadboard testing and then we shift our circuit to printed circuit board. This board will become final version of our project. All hardware components used in our project are described in this part. Through literature survey, we obtained guidelines for selection of each component for achieving best results and to obtain maximum efficiency at minimum expense. There are two basic parts of our hardware.

1. Mechanical Design
   • Robot Chassis

1. Electrical Design

• • Relay
  • H-Bridge
  • Processing Unit
  • Video Transmission
  • Wireless Communication

Raspberry pi is the main brain of our project in which we control the different operations that the robot performs along with it in-order to sense fire there are the fire sensor modules (flame sensor) attached at the input along. When fire burns it emits a small amount of Infra-red light, this light will be received by the IR receiver on the sensor module. Then the three flame sensors placed towards three different directions on the robot would determine the direction on which the fire is burning signaling the controller to move the robot in the specific direction which in turn signals the motors to start moving. The robot carries water in a 10 liters bucket mounted on it, a pump is attached with the container so that water can be sprayed with greater pressure for extinguishing the fire rapidly. This robot can be controlled by the operator through android application where the operator would be getting real time video footages of the surroundings with the help of a camera that is placed at the top of the robot. This control feature would enable the operator to direct the robot towards the first priority location for extinguishing fire. 

                   

Benefits of the Project

Due to attention to climate change, natural disasters and the human effects on earth comes into focus and becomes a great global concern, leading minds will search for ways to solve the continuing crisis. One of the most innovative and sustainable solutions emerging from climate change technology are fire fighter robots. Our project will extinguish the fire and prevents destruction of life, property and the environment. Small scale robotics have been around for quite a long time now. They have proved their mark in agriculture, surveillance, wildlife reserves and videography. People have been using them for security and rescue missions. Our project seeks the importance of small-scale robotics. This can be helpful in saving lives as well as effective against the natural disasters.

In the light of all the above mentioned uses and impacts we conclude that our project can bring change in our society from safety point of view and is an advancement in surveillance systems.

Living in this modern era of technological advancement, robotics has become the need of every field of life. Nowadays almost every industry runs on automation. Automation increases efficiency and productivity. Our fire fighter robot is beneficial for the environment and society both economically and physically. It provides benefits to the environment because:

• It is accurate
• It’s accomplishment of extinguishing fire is speedy
• It is more precise
• It has ability to detect fire and extinguish it in minimum time
• It can perform instead of putting human workers in danger
• It saves huge disasters by extinguishing the fire in its early phase

It is intelligent and user-friendly fire fighter robot.

Technical Details of Final Deliverable

We have used the Cayenne application to control the movement of our robot and to communicate the directions given to our robot. Cayenne is an android/iOS app which is used in mobile phones and different pc’s that allow to control the Raspberry Pi. We can add our own commands and widgets in this application which helps to control our robot with more duality and more options can be generated in this way. The features are:

• It alters the control board with the assistance of instinctive utilities for various associated gadgets.
• Create actuators and different types of limit alerts for various gadgets, occasions and activities.
• It plans one-time or multi-gadget occasions for the simple mechanization.
• It has a speedy and simple setup and it can interface with (RPi) in minutes..

Few of the options that we have created for our project in this application are:

1. Forward
2. Reverse
3. Left
4. Right
5. Valve 1
6. Valve 2

Cayenne Cloud is open source and works through the internet. This means that the hardware you choose must be able to connect to the Internet. Some of the cards, will need an Ethernet or Wi-Fi connection to communicate. It can work in your environment, locally, private Business Server or hosted on your machine. Cayenne Server can be implemented in minutes. It is in real time and is ready to manage billions of requests from its perimeter devices. It offers us to choose from a variety of predesigned widgets to create native iOS and Android applications that control electronics, monitor sensor data and receive notifications. Cayenne works efficiently with most Arduino boards, Raspberry Pi models, Particle Core and another common microcontrollers and single-board computers. The Wi-Fi and Ethernet shields of Raspberry Pi are compatible, although you can also control the devices connected to the USB port of a computer. It can control the digital and analog I/O pins on your hardware directly. We do not even need to write code for it. Virtual pins can send any information from their microcontroller to the Cayenne application and vice versa. The virtual pins can be used to interact with external libraries and implement customized functionality.

The Cayenne application has support for multiple devices. That means we can assign any widget to a specific device with its own authentication token. The tag feature allows us to group multiple devices. The tags are very useful in case we want to control some devices with 1 widget. Widgets are interface modules. Each of them performs a specific input / output function when communicating with the hardware.

There are 6 types of widgets:

• Forward: used to move robot towards forward direction
• Backward: used to move robot towards backward direction
• Left: used to move one wheel is forward and another is backward
• Right: used to move one wheel is backward and another is forward
• Valve 1: sprays water when sensor 1 is on
• Valve 2: sprays water when sensor 2 is on
