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:
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

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.

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

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

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.
