ABSTRACT

When we hear about robots, we think of science fiction novels and sci-fi movies. It is due to the fact that we do not know how to create robots of high intelligence. However recent trends in technology have made a significant contribution to robotics technology. A robot is a reprogrammable, multifunctional manipulator designed for performing a variety of tasks. Robots are used for avariety of industrial applications.

In industries and houses, fires and leakage of combustible gases will result in hazardous accidents. There are many possibilities a fire can start in an industry or in any remote area. For example, in paper industry, garments, fuel storages, etc.

INTRODUCTION

1. INTRODUCTION

1.1 PROJECT OBJECTIVE

Nowadays, machinery and robotic design become important in helping human. This Fire Protection Robot was design to help people in any destructive burnt situation where this robot can extinguish burnt area immediately using autonomous system.

This report illustrates the design and implementation of our team’s fire fighting robot for the Industrial Systems Design and Integration paper. The robot must run automatically, avoiding obstacles and at the same time find and track two flames (candle light) and extinguish them. To achieve the best performance with an effective implementation, we have taken a modular design strategy, where the robot is divided into a number of logical modules based on functionality.

Electric leakages can lead to huge damage. In order to avoid these we have developed a fire fighting robot. Our project is designed to sense fire in a building or house and extinguish the fire. The fire sensors are kept at certain important predetermined locations. When a fire occurs near a fire sensor it senses it and corresponding bit in the encoder will be set and is transmitted wireless to the RF receiver, connected to robot. Once the RF receiver receives the signal, the decoder will decode and informs which fire sensor is activated. The robot will move towards the corresponding fire sensor since the locations of the fire sensors are already stored in the memory of the robot. Once the robot reaches the location, movement of the robot will stop and will activate sprayer to extinguish fire. When the fire is extinguished, spraying is stopped and the robot will return to its initial position. Thus the robot will function effectively to control fire with minimum human intervention.

1.2 Project Scope

• The project scopes for this project are:

• The robot burnt area in 0m ~ 2m in radius.

• Robot detect fire event, and use extinguish to fight the fire source.

• The robot can turn 360° and then robot can extinguish fire at angle 30° from the fire extinguisher nozzle.

• The robot can extinguish fire from petrol, gasses and electrical appliance.

1.3 Problem Statement

The goals of this project are listed below:

 It must run using remote

 It must avoid any obstacles present

 It must track and find flames (candle lights) and extinguish them without making direct contact

 The security of home, laboratory, office, factory and building is important to human life. We develop security system that contains a fire protection robot using remote sensor. The security system can detect abnormal and dangerous situation and notify us. First, we design a fire protection robot with extinguisher for the intelligent building. Besides, Human had difficulties to detect the small burnt cause by electrical appliances. The late time user takes to extinguish the fire. User may take a late time to extinguish fire like finding the water source to extinguish fire when want to extinguish the fire. The fire difficulties to detect the small burnt area and location that is hard to be reach by the user. Sometimes tough fire extinguished for example spaces are hard to see. Besides is cost the loss suffered in the event of fire slow to act.

1.4 Project Description

 The project is designed to develop a fire fighting robot using RF technology for remote operation. The robotic vehicle is loaded with water tank and a pump which is controlled over wireless communication to throw water. A 212 series of microcontroller is used for desired operation. At the transmitting end using push buttons, commands are sent to the receiver to control the movement of robot either to move forward, backward and left or right etc. At the receiving end three motors are interfaced to microcontroller where two of them are used for movement of the vehicle and the remaining one to position the arm of robot.

 The RF transmitter  acts as a RF remote control that has the advantage of adequate range (up to 100 meters) , while the receiver decodes before feeding it to another microcontroller to drive dc motor via motor driver IC for necessary work.

• A water tank along with water pump is mounted on the robot body and its operation is carried out from the microcontroller output through appropriate signal from the transmitting end. The whole operation is controlled by a 212 series microcontroller. A motor driver IC is interfaced to microcontroller through which the controller drives the motor.  

CHAPTER 2

LITERATURE REVIEW FROM RESEARCH PAPER

2.1 Introduction

 This chapter are discussing about a study on the previous project based on fire fighter robot project and thesis. The entire project had been studied and analyzed their principles, method and applications.

2.2 Robot

 Robot is a machine that looks like a human being and performs various complex tasks. Now, let’s have a good look at existing firefighting robots.

  Virtual Reality Simulation of Fire Fighting Robot is a virtual adaptation of competition robot that took part in Panitia Kontes Robot Cerdas Indonesia competition in 2006. This system was developed in MATLAB/Simulink with the help of «Virtual Reality Toolbox» plug-in. It is oriented for initial testing of controlling algorithms. It’s important to notice, that even the robot itself doesn’t have enough level of functionality, because of low-detailed formalization of environment.

  The robot could operate only in corridor-room environment, without strange objects. Only one fire source is meant and there are auxiliary marks on floor that mean for example room entrance.

  Pokey the Fire-Fighting Robot is the firefighting robot that made its way out of competitions, and became more “serious” than other systems. In there are detailed description of used equipment and basic algorithms of operating. Robots operating environment is a building, so the robot is equipped with necessary remote sensors, for example, with a line remote sensor, that could be UN useful in conditions of dense smoke.

The main advantages of robot are:

• using of two types of fire remote sensors, working in different ways;

• using of complex firefighting tool;

The main disadvantages are:

• Short distance of remote sensor’s work. the fire could be recognized at the distance not more than 1.5m. at longer distances the remote sensors works bad, ad developers say

• low efficiency of onboard computer, able only to carry main tasks, without its extension and complexization;

• Absence of optical means of environment perception.

The modular design of our robot provides a number of advantages:

 We have a clear separation of tasks, and thus each team member is more likely to be able to meet the deadline.

 Having all components required for a particular set of remote sensors on a single board means that each team member can work independently, according to their own schedules.

 Because each board is independent, they can be tested independently before the integration step.

 Functionalities of the finished robot can be switched on and off by simply removing power from the individual modules. This makes debugging the final robot easier.

 Modular designs have many redundancies, and as such as less prone to component failures.

 Broken parts can be swapped out very quickly.

Encoder:

 The encoder which we are using in our project is HT12E. HT12E is an encoder integrated circuit of 212 series of encoders. It is mainly used in interfacing RF-circuits and IR-circuits. It encodes the 12 bit parallel data into serial form for transmission through an RF transmitter. These 12 bits are divided into 8 address bits and 4 data bits. HT12E has a transmission enable pin which is active low.

Decoder:

 The decoder which we are using in our project is HT12D.

 HT12D is a decoder integrated circuit that belongs to 212 series of decoders. The decoder is connected to RF receiver and it will indicate which fire sensor is activated. HT12D converts the serial input into parallel outputs. HT12D is capable of decoding 12 bits, of which 8 are address bits and 4 are data bits. The data on 4 bit latch type output pins remain unchanged until new is received. The chosen pair of encoder/decoder should have same number of addresses and data format.

CHAPTER 6

CONCLUSION

6. Conclusion

The above analysis gives us the following conclusions:

• There is a great progress in world remote controlled firefighting robots’ design. The next step is to make them to operate autonomous, by the gradual decreasing of human participation in device controlling process.

• The design of firefighting robots is a very urgent problem, especially in Russia, where this problem is solved poorly (autonomous movement is meant).

• The adequate formalization of environment is necessary for increasing precision of autonomous operating. The competition ideology must be forgotten, and the real conditions are should been taken into account.

CHAPTER 7

FUTURE SCOPE

7. Future Scope

  This project has been motivated by the desire to design a system that can detect fires and intervention. In the present condition it can extinguish fire only in the way and not in all the rooms. It can be extended to a real fire extinguisher by replacing the fan by a carbon-di-oxide carrier and by making it to extinguish fires of all the room using microprogramming. This provides us the opportunity to pass on to robots tasks that traditionally humans had to do but was inherently life threatening.

Fire-fighting is an obvious candidate for such automation. Given the number of lives lost regularly in firefighting, the system we envision is crying for adoption. Of course, this project has only scratched the surface. As in the design simplifications and the implementation constraints in suggest, our project is very much a proof-of-concept. In particular, a practical autonomous fire-fighting system must include a collection of robots, communicating and cooperating in the mission; furthermore, such a system requires facilities for going through obstacles in the presence of fire, and ability to receive instructions on-the fly during an operation. All such concerns were outside the scope of this project. However, there has been research on many of these pieces in different contexts, e.g., coordination among mobile agents, techniques for detecting and avoiding obstacles, on-the-fly communication between humans and mobile agents, etc. It will be both interesting and challenging to put all this together into a practical, autonomous fire-fighting service.
