INTRODUCTIONINTRODUCTION::The Google Driverless Car is like any car, but: It can steer itself while looking out for obstacles.

It can stop and go itself based on any traffic

condition.

It is a combination of different technologies

developed by Google

That will allow a car to drive itself even on

the highway

Contd:Contd:

The project is currently being led by: Sebastian Thrun

Director of the Stanford Artificial Intelligence Laboratory

2005 DARPA Grand Challenge Winner Co-inventor of Google Street View


Contd:Contd:

Uses Google map, sensors, artificial intelligence

Lidar produced detailed map of the environment

Car uses white stripes on road to know lanes

360 degree motion sensor and cameras to sense

Control of the car still exist

Sensors pushing data into main computer to

process information


COMPONENTSCOMPONENTS::

Integrates Google Maps with various hardware sensors and artificial intelligence software Google MapsProvides the car with road information

Hardware SensorsProvides the car with real time environment conditions

Artificial IntelligenceProvides the car with real time decisions


GOOGLE MAP: GOOGLE MAP:

Speed Limits.

Upcoming intersections.

Traffic Report.

Nearby collisions.

Directions.

Google Maps interacts with GPS and acts like a database.


HARDWAREHARDWARE SENSORSSENSORS::

The hardware sensors gives real time environmental properties.

Environment is dynamic so need real time results.

Sensors attempt to create fully observable environment.


HARDWARE SENSORS:HARDWARE SENSORS:

LIDAR VIDEO CAMERA POSITION ESTIMATOR DISTANCE SENSOR


LIDARLIDAR

“Heart of our system“

LIDAR is an optical remote sensing technologyMeasure the distance to, or other properties of a

target It often using pulses from a laser.

Scanning distance of 60 meters (~197 feet)


VIDEO CAMERAVIDEO CAMERA

Detects upcoming traffic light.

Recognizing moving obstacles like pedestrians and vehicles

DISTANCE SENSORDISTANCE SENSOR

Allow the car to "see" far enough to detect nearby or upcoming cars or obstacles

It also contain radar


Contd:Contd:

object returns a tiny part of the wave’s energy to a dish

Radar system has a transmitter that emits radio waves called radar signal

Doppler effect


POSITION ESTIMATOR(Wheel POSITION ESTIMATOR(Wheel EncoderEncoder))Determines vehicle's location and keeps track of its movements.

GPS is a space based satellite navigation system that provide location and time information

It is maintained by the US government

It freely accessible by anyone with a GPS receiver


ARTIFICIAL INTELLIGENCE:ARTIFICIAL INTELLIGENCE:

Google Maps and the hardware sensors data are sent to the AI.

AI then determines:

how fast to accelerate when to slow down/stop when to steer the wheel

Goal of AI

The agent's goal is to take the passenger to its desired destination safely and legally


WORKINGWORKING

The motors are first have to be installed

Apply pressure to both accelerator, brake pedals

and turn the wheels

Motor receiving instructions from computer

Lidar used to detect objects and distance

video cameras detect traffic light

Control of the car would still exist


LET'S SEE IT IN ACTION!LET'S SEE IT IN ACTION!

A look from the inside... A look from the outside...


ADVANTAGESADVANTAGES

Improved fuel efficiency

It will be of great help to people who are

physically challenged

Higher speed limit for autonomous cars

Reduction of space required for vehicle parking.

Fewer traffic collision


DISADVANTAGESDISADVANTAGES

So many taxi drivers can lose their jobs

It steals driving pleasure from drivers who love it

It requires that the road are in good condition and follows a strict traffic system


CONCLUSION:CONCLUSION:

Very useful .

Avoid accidents on the road

Reduce the traffic time at traffic signal

So many taxi drivers can loss their job

Vehicles could be ready for market in as

little as three to five years.
