How has artificial intelligence helped us improve services in life? Explain that.

Learn

In previous years in the primary stage, you studied the definition of artificial
intelligence and some of its uses in our daily lives. In this lesson, we will
discuss the types of artificial intelligence and its applications in our lives.

Types of Artificial Intelligence:

Artificial intelligence is not just one type, but there are many and varied
types. Imagine that we have a large garden full of different flowers, each
flower has a different shape and color, and so is the case with artificial
intelligence.

6

oNarrow AI:

This type of artificial intelligence focuses on
performing a specific task, such as recognizing
faces or translating languages. Another
example is a robot that can play chess
brilliantly, but it cannot do anything else.

oGeneral artificial intelligence (GAI):

This type of artificial intelligence is more advanced, and can perform any
task that a human can do. Example: A robot that completely mimics a
human, as it can think, innovate, solve complex problems, learn, and
adapt to different situations.

oSuper artificial intelligence (SAI):

This type of artificial intelligence is the most advanced; it can solve
problems that are difficult for humans to solve easily, and discover
new things that we have never imagined before.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, search for the uses and the applications of artificial intelligence in
our daily lives?

Applications of artificial intelligence in daily life:

Personal Assistant: Do you have a friend who talks to

you, answers your questions, and performs tasks? This is
the personal assistant like (Siri) or (Alexa), it uses
artificial intelligence to understand your commands and
perform them.

Smart Games: Do you play video games? Some of these

games use artificial intelligence to make the game more
fun and challenging, as the characters in the game can
learn from their mistakes and become smarter.

7

Smart Cars: Have you ever imagined a car driving itself

without a driver? This is the dream of the future that is
getting closer to being realized thanks to artificial
intelligence.

Digital Doctors: Doctors use artificial intelligence to help

them diagnose and treat diseases faster and more
accurately.

Instant Translator: Have you traveled to another country

and spoken a different language? Artificial intelligence can
translate words and sentences instantly, making it easier
for people to communicate.

Smart Shopping: Have you noticed that shopping sites

offer you suggestions for products that you might like?
This is thanks to artificial intelligence that analyzes your
previous purchasing behavior.

Artificial Intelligence Fields

1. Machine Learning - Learning from Mistakes:

oAI has to learn new things, the more we show it a picture of a cat, the more it

learns to name it, and the more we play a game with it, the smarter it becomes,
this is called Machine Learning, and it is similar to when you learn to ride a
bike, the more you fall, the better you learn how to balance.

2. Natural Language Processing - Understanding Languages:

oCan you imagine talking to your computer as if it were a friend? It

understands our different languages and can answer our questions. This is
Natural Language Processing, and it is like an intelligent language
translator as it understands written and spoken human language, interprets it,
and learns to "speak" human language.

3. Computer Vision - Sees the World:

oAI can look at a picture and tell you everything in it, and it can find your

face in a crowded picture, and distinguish between pictures of different
animals, which is called Computer Vision.

4. Robotics:

There are smart robots that do many tasks such as cleaning the house, playing
chess, or performing complex and precise surgery, and they have the ability to
work with great accuracy even in environments that are dangerous to humans.

5. Simulation of human thinking and decision-making - Expert Systems:

Artificial intelligence can solve complex problems and make difficult decisions.
This is the field of expert systems. It is similar to an intelligent doctor who can
diagnose diseases.

6. Simulation of human learning - Deep Learning:

Deep learning aims to enable computer systems to learn complex tasks in a way
similar to the way humans learn. Artificial intelligence has a mind similar to the
human mind. It uses this mind to learn things very quickly. Deep learning relies
mainly on neural networks and deep learning.

9

Create intelligent models to recognize images, sounds, and movements using
machine learning (Teachable Machine):

Imagine if you could teach a computer to recognize objects in the same way you
learn! This is exactly what Teachable Machine does, an easy-to-use tool that helps
you create intelligent models to recognize images, sounds, and movements.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, download the Teachable Machine website.

Note: It is preferable to update your internet browser and work on the Microsoft
Edge browser.

Click on the following link to enter the websitehttps://teachablemachine.withgoogle.com/"

Model Building Training:

Imagine that you are training a young child to do new things! First, you need to
teach him the names of things.

You show the young child a picture of a cat and say, “This is a cat,” then you

show him a picture of a dog and say, “This is a dog.”

You are telling the child what things he sees, just as you teach him the names of

letters and numbers.

10

After the young child sees a lot of pictures and hears names, his little brain

starts to understand the difference between a cat and a dog, just like when
scientists try to train a computer to understand pictures and sounds.

The child has learned so well that he can now tell the difference between a cat

and a dog on his own, and in the same way, the computer has learned to
recognize different things, and we can use it for a lot of fun things!

Imagine that we want to teach the computer to recognize numbers. We can start by
giving him pictures of numbers from “0-9,” and telling him what number is in each
picture. After a while, the computer will be able to look at any number and tell us
what it is.

Website login window layout

Ready to explore the world of
photography? Our first project will take
you on an exciting journey!

The images of numbers from "0-9" are
prepared in the form of images of files
stored on the computer.

11

1. Classification that includes a group of images that belong to a specific category
such as images of numbers "from 0-9" and another classification that includes
images of alphabet letters.

2. Upload images of numbers in (Class1).

12

3. Open the camera, prepare images of numbers on paper boards" and have the
model take them in (Class2),

Note: The images were provided to the model in the form of files or he takes
them through the Web camera.

4. The artificial intelligence model is trained on the image categories that were
given to it.

5. Add more image categories when needed, for example "adding special symbols".

6. After that, the model can be given an image that determines for us which
category of images it follows.

Save the project:

1- Save the project on Google Drive…

2- Download the project to the device..

Practical example:

Suppose you want to make a game where you control a character on the screen
with your hand movement, here are the steps:

Training: You record your hand in different positions (such as raising the hand,

lowering it, moving it right and left).

Recognition: Teachable Machine learns to associate each position of your hand

with a specific movement of the character on the screen.

Game: When you move your hand in front of the camera, the character on the

screen moves according to what the computer has learned.

13

Example application:

Access the site:

Open your browser and type "Teachable Machine" in the search bar, then access
the site.

Select the training model:

We find several options, choose the option related to image recognition (Image).

Prepare the camera:

The site will ask you to choose to upload images (upLoad) or allow it to use your
device's camera (web). Click on the camera (web) and make sure that the lighting
is good and the camera background is simple so that the computer focuses on the
movement of your hand.

Train the computer.
Create Classes:

Create at least two classes (Class1) and (Class2), for example (Class1) "Raised
hand" and (Class2) "Shaky hand".

Record examples: In front of each category, record several examples of the

corresponding hand movement, for example, in front of the category "raised
hand", raise your hand several times and each time raise it with a specific
movement or a different shape, and so on in front of the category "shaky
hand".

Review examples: Make sure that the examples are clear and that the

computer understands the difference between the two movements.

Training: After you finish taking the pictures, click on the "Train Model"

button to teach the computer these movements.

Test the model: After you finish training, the site will ask you to test the

model.
oCamera: Point the camera at your hand and perform the movements you

trained.

oResults: You will see that the computer will try to guess the movement you

are performing.

Save the model: If you like the model, you can save it and use it in other

projects.

14

Ideas for your projects:

Recognize faces: Train the computer to recognize the faces of your friends

and family.

Create a motion control game: Use your body movements to control

characters in a video game.

Image classification: Teach the computer to classify images into different

categories (such as animals, food, colors).

Create a robot that follows you: Build a small robot that follows you

wherever you go.

How do sensors work? What devices have you seen or
used in your life?

Learn

In this lesson, we will learn about one of the most important concepts in the
world of modern technology, which is sensors. These simple devices play a
major role in our daily lives, from their use in robots to their use in our
smartphones, modern cars, and alarms.

We will learn together how these devices work and what their types are, and
we will review real-life examples that help us understand how theywork and
how they are used in electronic devices and robots.

Sensors: They are devices that sense changes in the
surrounding environment and convert them into signals so
that machines and devices can understand them and make
appropriate decisions based on them. They are considered the
eyes and ears of machines.

18

How do sensors work?

Have you ever wondered how the sensation of light, heat, or sound is converted
into numbers in a computer? Imagine that the sensor is a translator that translates
those sensations (such as heat, light, or sound) into a language that the computer
understands, which is the language of numbers. Sensors work through 3 main

steps:

1. Sensing: Captures information from the surrounding environment (such as heat,
light, or sound).

2. Signal Conversion: Converts this information into electrical signals that can be
read by electronic devices.

3. Transmission: Signals are sent to another device to display the results or
perform a specific operation. For example, a thermometer displays the temperature
result on a digital screen.

The importance of sensors for robots:

Imagine robots without sensors, they would be like a person walking with their
eyes closed and their ears covered, they cannot recognize what is happening
around them or recognize those around them or how to behave, here comes the
importance of sensors, they represent the "senses" of the robot, helping it to see,
hear, sense, and even touch things around it.

- Types of robotic sensors:

There are many different types of sensors used in robots, and each type has a
specific function.

Here are some examples:

Distance Sensors: Measure the distance between the robot and surrounding

obstacles, this helps the robot avoid collisions.

Light Sensors: Used in robots that operate in places where light is variable,

such as home robots, these sensors help the robot adapt to changing light
conditions.

Sound Sensors: These are used in robots that react to sounds, for example:

robots that can respond to voice commands.

19

Motion Sensors: These detect movement and changes in direction. These

sensors help the robot navigate and interact with surrounding objects.

Special Sensors: Such as temperature and humidity sensors.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, mention examples of electronic devices that use sensors?

Some examples of electronic devices that use sensors:

Vacuum cleaner robot: uses sensors to avoid obstacles and clean under

furniture.

Surgical robot: uses precise sensors to perform surgeries.
Self-driving cars: rely heavily on sensors to see the road and make

decisions.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, discuss with your colleagues the types of distance sensors?

Types of distance sensors and examples of them:

The types of distance sensors used in robots and smart devices vary, and each type
has its own advantages and uses. Here is a detailed explanation of the types of
these devices with illustrative examples:

1- Ultrasonic Sensors:

Working principle: These devices emit high-

frequency sound waves, then receive the returning
waves after they bounce off an object, and by
measuring the time it takes for the wave to return,
the distance to the object can be calculated.

Examples:

oVacuum cleaner robots: These devices are used to locate furniture and

obstacles to avoid colliding with them.

oParking systems: They help measure the distance between the car and

surrounding obstacles.

20

oFluid levels: They are used to measure the level of fluids in tanks and

reactors.

2- Laser Rangefinders:

Working principle: These devices emit a laser

beam and then measure the time it takes for the
beam to return after bouncing off the object,
and are characterized by high accuracy and a
longer range compared to ultrasonic devices.

Examples:

o3D laser scanners: They are used to create

3D models of spaces.

oGround scanning systems: They are used in geological and

archaeological surveys.

oIndustrial measurement systems: They are used to measure dimensions

with high accuracy in various industries.

3- Visible Light Sensors:

Working principle: These devices use digital cameras to analyze images

and determine the distance to objects based on the size and distortion of the
image.

Examples:

oSelf-driving car cameras: used to determine

the distance to other cars, pedestrians, and
traffic signals.

oIndustrial vision systems: used to inspect

products and identify errors.

oAugmented reality systems: used to integrate

digital elements with the real world.

4- Infrared Sensors:

Working principle: These devices emit infrared

rays and then receive the returning rays after they
bounce off the object, widely used in consumer
electronics.

21

Examples:

oRemote controls: Infrared rays are used to communicate with electronic

devices.

oNon-contact thermometers: Used to measure body temperature without

the need for direct contact.

5- Time of Flight sensors:

Working principle: It depends on measuring the

time it takes for a light pulse to reach an object
and return to it, characterized by high accuracy
and high speed.

Examples:

o3D sensors: Used to create 3D models of

objects.

oMotion tracking systems: Used in video games and virtual reality

systems.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, discuss the factors for choosing the appropriate type of sensor?

Choosing the appropriate type of sensor depends on several factors, including:

Required range: The maximum distance that the device must measure.
Required accuracy: The required measurement accuracy.
Operating environment: The environmental conditions in which the device

will operate (lighting, temperature, humidity).

Cost: The cost of the device and installation.

By choosing the appropriate device, robots and smart devices can interact
with their environment more accurately and effectively.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, mention electronic devices that you use in your daily life and that
depend on sensors in their work?

22

Daily applications of sensors:

Sensors are used daily in our lives, and the most prominent of these applications
are:

In smartphones: There are sensors that help in taking pictures, adjusting the

lighting level, and even determining the location of the phone.

In modern cars: Sensors are used to determine speed, warn of collisions,

and help the driver park his car.

In smart homes: Motion sensors turn on the lights automatically when

someone enters the room.

Phone microphone: It is a sound sensor that converts the sound you pick up

into electrical signals that can be understood by the phone.

Motion sensor in games: When you tilt your phone to the right or left while

playing a game, the motion sensor is what tells the game to change the
direction of the character.

Touch screen: It is a group of small sensors that sense where your finger

touches the screen.

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues - and with the help of the science teacher, use a temperature sensor.

Practical activity:

Required materials:

Temperature sensor.
A cup of hot water.
A cup of cold water.

Steps:

1.Measure the temperature of the hot water using the temperature sensor.
2.Repeat the process with cold water.
3.Notice the difference in temperatures displayed on the device screen.

What is a robot? What functions can a robot perform? Explain?

Learn

The world is full of amazing robots that can do incredible things! Can you imagine
a robot that can clean your room, another that can help you with your daily tasks?
Or maybe a small robot that runs and plays with you like a pet! Robots can help us
in our daily lives and in various fields.

Definition of Robot:

A robot is a device that can be programmed to perform a set of specific tasks
automatically. The robot can move, sense (via sensors), and interact with its
surroundings and can be used in environments that require precision and speed of
performance.

Example:When we see a vacuum cleaner moving by itself in the house to clean
the floor, this is a type of robot that works independently.

1- Types of robots: There are several types of robots, including:

28

Industrial robots:

They are robots used in factories, and they can perform work with high
accuracy, such as robots that work in car production plants on production
lines quickly and accurately.

Home robots:

These robots are found in homes, cleaning
robots such as Roomba that help clean floors
without any human effort, such as smart
vacuums.

Medical robots:

Medical robots help doctors perform surgeries,
and they can be very accurate.

Educational robots:

These robots are used in schools to teach students how to program and
technology, such as LEGO Mindstorms robots that can be programmed to
perform specific tasks, to help students and to be an aid to the teacher.

Types of Robots

Activity:

Dear student, with the help of your teacher and in cooperation with your
colleagues, discuss with your colleagues the components of the robot.

29

2- Robot components:

Structure

The structure is the main part that
carries all the components of the
robot. It can be made of different
materials such as metal, plastic, or
carbon. The design of the structure affects the weight of the robot and its
ability to move.

Sensors

Sensors are the senses of a robot.
Just as we use our eyes to see and
our ears to hear, a robot uses sensors
to pick up information from its
surroundings. Some examples of
sensors are:
oSound sensors: pick up and

analyze sounds.

oCameras: help robots “see”

things in front of them.

Motors

Motors are used to move parts
of a robot. There are different
types of motors, such as
electric motors and pneumatic
motors, each with its own
uses. Motors are the industrial
muscles of robots. Thanks to
motors (actuators), robots can
move and execute commands.
oMotors: make robots

move.

oRobotic arm: used in factories to move objects with precision.

30

Controller:
The controller is the “brain” of

the robot, processing the data
collected by the sensors and
issuing commands to the motors.
The controller can be as simple
as electronic circuits or as
complex as microcomputers. Just as our brain thinks when we decide to
move, the processor makes the decisions necessary to move the robot.

Power Source:

Robots need a power source to
operate. Power sources can be
batteries, solar cells, or even
direct electrical power sources.
The choice of power source
depends on the type of robot and
the required operating time.

Software:

Software is what makes a robot
“smart.” Software includes
algorithms that determine how
the robot responds to information
it receives from sensors.
Software can range from simple
programs to complex artificial
intelligence systems.

Communication tools:
Robots use communication tools

to interact with users or other
robots. These tools can include
Bluetooth, Wi-Fi, or other
communication technologies.

31

Example:A home robot, such as a robot vacuum cleaner, has sensors to avoid
collisions with furniture and room walls.

3- Areas of use of robots:

Robots have become part of our daily lives and are used in several fields, such as
medicine, industry, and education.

For example, in hospitals, there are robots that perform precise surgeries, while in
factories, they help manufacture cars. Robots have many applications in
different fields, including:

Industry: Improving productivity and reducing human errors.
Healthcare: Assisting doctors in surgeries or providing care for patients.
Education: Providing interactive educational experiences for students.
Agriculture: Using robots in precision agriculture to increase crops and

reduce waste.

line color and size using the blocks in the “Pen” section. For example,
you can use the “Set Pen Color to” block to choose a specific color, and the
“Set Pen Size to” block to set the line thickness.

4.Moving the Pen: Now, we will move the pen to draw the shape we want. Use

the “Go to x:y:” block to set the starting point, and then use the “Go to x:y:”
block again to set the ending point. This will make the pen draw a straight line
between the two points.

5.Repeating Steps: Repeat the previous steps to draw more lines and

form the shape you want.

Notes:

Drawing different shapes: You can draw any geometric shape by setting

the start and end points of the lines appropriately.

What is Python:

Before we start defining Python, we must know that the first version of the
language was in 1991. It is a programming language widely used in data science
and machine learning, and for developing websites and applications.

Features of Python:

1.Open source: Python is free and open source, allowing everyone to use and

develop it.

2.Interpreted language: Which means that it translates programming codes line

by line, so if there are errors in the program code, it will stop working, as
programmers can quickly find errors in the codes.

3.Versatility: It can be used in developing web applications, data science,

artificial intelligence, machine learning, and game programming.

63

4.Easy-to-use language: It is one of the easiest programming languages for

beginners because of its simple and organized formula and uses words similar

to English, unlike other programming languages.

5.Integration: Python can be integrated with other languages such as C, C++,

and Java, and it can also be used in developing multi-platform programs.

6.Libraries: Python has many libraries that you can use.

Python Libraries

They are pre-built codes and functions that help programmers perform specific
tasks without having to write codes from scratch, libraries are a powerful tool
that increases the efficiency and effectiveness of programming using Python, as
they provide ready-made solutions to many common problems or requirements.

like:

NumPy: is a library widely used in data science, statistics, and artificial
intelligence.

Pandas: is a library for analyzing and processing data.

Matplotlib: is a library for creating graphs and charts

What are variables in programming languages? How can they be written and
classified?

Learn

Variables in programming languages express a reserved place in memory to store

and save a specific value, where the value can change (example: Taher= 20) In this

example, we expressed a variable named (Taher) and its value is equal to (20),

where you can change the value of the variable while dealing with the program

immediately during the execution of the program.

Conditions for naming variables in Python:

1.The variable name begins with a letter or an underscore _.
2.The change name contains letters (A-Z) or numbers or an underscore _
3.Reserved words may not be used in Python because they express specific values

that the program understands (example: False) A reserved word within the
program is a word that indicates a reserved value (logical value).

70

Dear student… When writing a variable name, you must take into account placing
the variable names in upper and lowercase letters (example: TAHER, Taher, taher,
TaheR) In the previous example, the variable names refer to four variables and not
one variable.

Types of variables in Python

1- Numbers: Used to store numerical values such as integers (int) and decimals

(float).

Integer variables:

X= 5

Y= 10

Decimal variables:

Z= 5.25

A= 8.32

2- Strings: Used to store texts such as names and addresses.

Texts are placed between single quotes ‘ ’ or double quotes “ ”

Name = “Taher”

City = ‘Cairo’

3- Booleans: A data type that contains only two values True or False

Often used in comparisons and decision making in codes

Is_taher_student = False

Is_taher_a_teacher = True

71

Python program interface

1- Through the interactive Python interface (Python Shell): You can write

simple codes and execute them directly to see the results.

2- Text editor: It allows you to write longer and more complex

codes and save them to run later.

The interactive Python interface is installed when you install the Python
language, and there is no need to download it, unlike a text editor that must
be downloaded from the Internet, such as Visual Studio and PyCharm.

To know the type of the variable you can use the type ( ) function

72

Simple Python Code Using Variables

The print function ( ) in Python is one of the most commonly used functions,
used to display text or values on the output screen. It can be used to display
text, variables, or even the results of mathematical operations.
