Introduction
to Robotics

Robot/s
is a machine—especially
one programmable by
a computer which
capable of carrying out a
complex series of actions
automatically.

Robotics
deals with the design,
construction, operation,
and use of robots, as well
as computer systems for
their control, sensory
feedback, and information
processing.

What
people think
about
Robotics?

What
people think
about
Artificial
Intelligence?

Is artificial
Intelligence =
Robots?
Question:

Artificial Intelligence
> Robots.
Answer:

“Artificial intelligence is the
study of how to make
machines that can think and
act like humans, that are able
to learn and use their
knowledge to solve problems
on their own“

AI
Weak AI
(narrow AI)
Machines simulate intelligence
Machines can demonstrate
intelligence, but don´t
necessarily have a mind, mental
states or consciousness (experts
systems, speech recognition,
natural language
understanding)
Strong AI
(General AI)
Machines are intelligent
Artificial intelligence that
matches or exceeds
human intelligence
(“robotic”)

Computer Vision

”Acquiring, processing, analyzing
and understanding digital images,
and extraction of high-
dimensional data from the real
world in order to produce
numerical or symbolic information,
in the forms of decisions”

Image processing
is a method to convert an image into
digital form and perform some
operations on it, in order to get an
enhanced image or to extract some
useful information from it.

Artificial Vision Systems (AVS)
• The detection, segmentation, localization
and recognition of objects or things inside
the images ( for example human faces,
patterns, shapes or features).
• improvement and restoration of images.
• Image Analysis and interpretation of
images.
• Tracking of objects inside a sequence of
processed images (video).

The eyes, let us
collect information
from the environment
like object colors,
form, size, depth
The brain takes
the information
which is taken
for the eyes and
using all this
information (that
has been stored
inside
throughout our
live) in order to
let us classify,
identify,
differentiate the
objects, the
things etc.

Digital Representation of Images.

•A digital image is a matrix or
two-dimensional array of
numbers.
•Each cell in the matrix
represents a pixel.Sample:
Image of 20x15.

Digital Representation of Images

Digital Representation of Images
An Image can also be displayed / visualize or interpret using
• as a two dimensional
surface.
• As a discrete sampling
of the continuous
signal

Operation between images
What is the theoretical basis of image
processing?
digital image is nothing more than a matrix or
two-dimensional array of numbers.

Operation between images
We can apply the same
operations that covers any
number: add, subtract,
multiply, divide, apply and,
or, maximum, minimum,
integrals, derivatives ...
