GAS LEAK
A 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.

4. 4
GAS 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.

5. 5
PROJECT IDEA
Gas Sensor + Robot =
Safe solution for Gas
Leak Detection

6. 6
DESIGN OF ROBOT
Design Goals
•Robot should be tiny .
•Should be agile.
•Should work regardless of terrain.

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

8. 8
DESIGN OF QUADCOPTER
Components
•Brushless DC Motors
•Three Axis Electronic Gyro
•Three Axis Electronic Accelerometer
•RC Transmitter
•Flight Control Board
•Wireless Transmission Shield
•Leakage Alarm

WORKING 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.

10. 10
WORKING OF QUAD COPTER…
HORIZONTAL MOTION
Accomplished by speeding up motors (increasing thrust) on one side
and reducing it on the other.

11. 11
WORKING OF QUAD COPTER…
ALTITUDE CONTROL
Altitude control or change is accomplished by speeding up or slowing
down all motors at the same time.

12. 12
WORKING OF QUAD COPTER…
EXTENDED CONTROLS

GAS 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.
