INTRODUCTION

PROJECT IDEA

DESIGN OF UAV

ADVANTAGES

APPLICATIONS

3GAS LEAKA gas leak is a non-expected release of gas that can create a potentially dangerous situation - either because the released gas is poisonous or because it can ignite and create an explosion.

4GAS LEAK…It is generally unsafe for human inspection at a site of gas leak.

Especially if the environment is unsupportive like mines, caves and factory pipelines.

5PROJECT IDEA

Gas Sensor + Robot = Safe solution for Gas

Leak Detection

6DESIGN OF ROBOT

Design Goals

•Robot should be tiny .

•Should be agile.

•Should work regardless of terrain.

7DESIGN OF ROBOT…Quadcopter UAV is best suited as per our design

goals

8DESIGN OF QUADCOPTER

Components

•Brushless DC Motors

•Three Axis Electronic Gyro

•Three Axis Electronic Accelerometer

•RC Transmitter

•Flight Control Board

•Wireless Transmission Shield

•Leakage Alarm

9WORKING OF QUAD COPTER

YAW

Opposite pair of motors spins in opposite directions

Copter turns (Yaw) right or left by speeding up one pair and slowing the other pair of motors.

10WORKING OF QUAD COPTER…

HORIZONTAL MOTION

Accomplished by speeding up motors (increasing thrust) on one side and reducing it on the other.

11WORKING OF QUAD COPTER…

ALTITUDE CONTROL

Altitude control or change is accomplished by speeding up or slowing down all motors at the same time.

12WORKING OF QUAD COPTER…

EXTENDED CONTROLS

13GAS SENSOR

MQ-4

We plan to use methane sensor in our project.

MQ-4 is sensitive to Methane, Butane and Propane.

The type of sensor can be changed to detect various other gases.
