Introduction
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
MindBehind
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
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
Components
Integrates Google Maps with various hardware
Sensors and artificial intelligence software
Google Maps
Provides the car with road information
Hardware Sensors
Provides the car with real time environment
conditions
Artificial Intelligence
Provides the car with real time decisions.
Google map
Google Maps interacts with GPS acts
like a database
Speed Limits.
Upcoming intersections
Traffic Report.
Nearby collisions
Directions
Hardware sensors
The hardware sensors gives real time
environmental properties.
Environment is dynamic so need real
time results.
Sensors attempt to create fully
observable environment.
Lidar
Video camera
Position estimator
Distance sensor
Lidar
"Heart of our system"
LIDAR is an optical remote sensing
technology
Measure the distance to, or other
properties of a target
It often using pulses from a laser.
Scanning distance of 60 meters (~197
feet)
Video camera
Detects upcoming traffic light
Recognizing moving obstacles like pedestrians
and vehicles
Distance sensor
Allow the car to "see" far enough to detect nearby or upcoming
cars or obstacles
It also contain radar
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 Encoder)
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
Google Maps and the hardware
sensors data are sent to the Al
Al then determines:
How fast to accelerate
When to slow down/stop
When to steer the wheel
Working
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
Advantages
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
Disadvantage
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
Very useful.
Avoid accidents on the road
Reduce the traffic time at traffic signal
So many taxi drivers can loss their job
Thank you
