An autonomous vehicle uses sensors like radar, LIDAR, GPS and computer vision to navigate without human input. Radar uses radio waves to determine distance, speed and track objects. LIDAR uses lasers to precisely map physical features. GPS provides maps, directions and real-time traffic data. Computer vision allows the vehicle to analyze images of the road and environment. Together these technologies allow autonomous vehicles to drive itself, potentially reducing accidents.

2.  An autonomous car, also known as robotic or informally
as driverless or self-driving, is an autonomous vehicle capable of
fulfilling the human transportation capabilities of a traditional car.
 As an autonomous vehicle, it is capable of sensing its environment
and navigating on its own.
 A human may choose a destination, but is not required to perform
any mechanical operation of the vehicle.
 Autonomous vehicles sense the world with such techniques
as RADAR, LIDAR, GPS and computer vision.
 Advanced control systems interpret the information to identify
appropriate navigation paths, as well as obstacles and relevant
signage.
 Reduces the risk of accidents and improves drive quality.

5.  RAdio Detection And Ranging
 A radar system transmits radio waves called radar
signals in predetermined directions.
 Radar signals are reflected especially well by materials of
considerable electrical conductivity—especially by most
metals.
 The information provided by radar includes the bearing
and range (and therefore position) of the object from the
radar scanner.
RADAR

6. RADAR USES:
Distance measurement
Speed measurement
Reduction of interference
effects
Plot and track extraction
Frequency modulation

7.  LIght Detection And Ranging.
 It is an optical remote sensing technology that can
measure the distance to, or other properties of a target by
illuminating the target with light, often using pulses from
a laser.
 A narrow laser beam can be used to map physical features
with very high resolution
LIDAR/LADAR

9.  The Global Positioning System (GPS) is a space-
based satellite navigation system.
 Contains all types of maps, like streets maps, which may
be displayed in human readable format via text or in a
graphical format.
 Provides directions directly to an autonomous vehicles.
 provides information on traffic conditions (either via
historical or real time data) and suggesting alternative
directions
GPS

12.  Computer vision is a field that includes methods for
acquiring, processing, analysing, and understanding images
and, in general, high-dimensional data from the real world
in order to produce numerical or symbolic information.
 Typical tasks for computer vision are Recognition, Motion
analysis, scene reconstruction & image restoration.
