Robots and Their Applications
Today, some of the most boring and
repetitive jobs in manufacturing are
done by robots. The military and police
use robots for dangerous jobs, such as
manipulating explosive devices. Robots
are used in inaccessible places, such as
exploring our solar system or the bottom
of the sea. Robots also appear in
entertainment, research, medicine, and
education. Mankind is only beginning to
see the use and value of robotics.

Lesson 1: Robots and Their Applications

Each group is composed of (6) six
members . One will be assigned as
a leader to give a command to the
members. And the remaining members
will serve as the body parts
1. the right arm
2. left arm
3. body,
4. left leg
5. right leg

Commands:
 Let the right arm touch the left leg.
 All the left parts will touch the body.
 Bend the right leg.
 Bend the left leg.

Guide questions:
1.What is the help or purpose of the leader in the team?
1.2. If in case there is no command given, do you think the movement will be
organized?
3. For the five body parts, how do you see yourself if you are not working with the
command of the leader?
4. From our activity, what can be the relationship of robots and human?
5. Where do you think this idea of creation came from?

 A Robot is also called a droid. It is a machine—especially one
programmable by a computer—capable of carrying out a
complex series of actions automatically.
 Robots can be guided by an external control device or the
control may be embedded within.
 Robots may be constructed to take on human form but most
robots are machines designed to perform a task with no regard
to how they look.
 Robots can be autonomous or semi-autonomous.

According to history, many sources show the
popularity of automatons (a moving mechanical
device made in imitation of a human being or
robot) in ancient and Medieval times. Ancient
Greeks and Romans developed simple
automatons for use as tools, toys, and as part of
religious ceremonies. As the modern robots in
industry occur, the Greek God Hephaestus was
supposed to have built automatons to work for
him in a workshop. Unfortunately, none of the
early automatons still exist.
He is the Greek God Hephaestus.

Activity 2:

examples:
1. Burglar alarms incorporate a microcontroller chip,
which is connected to the keypad, display and
sensor/contact inputs.
2. Older automatic washing machines used a cam switch
for sequencing the operations during a wash cycle. This
was quite a complex switch and was mounted on the end
of the shaft of the knob you used to select a wash
program. Newer machines use a microcontroller to
sequence operations. Other appliances such as microwave

The Arduino is a powerful prototyping
tool for many reasons, including its lack
of a dedicated programmer, its wide range
of available libraries, and
the simplicity of its IDE. While we only
got a light to blink in this project, you
can expect much more in the future. Try
your hand at interfacing with
displays, taking measurements, talking
over the Internet, and possibly even
working with AI!

 Arduino IDE is an open source software that is mainly used for
writing and compiling the code into the Arduino Module.
 It is an official Arduino software, making code compilation too
easy that even a common person with no prior technical
knowledge can get their feet wet with the learning process.
 It is easily available for operating systems like MAC, Windows,
Linux and runs on the Java Platform that comes with inbuilt
functions and commands that play a vital role for debugging,
editing and compiling the code in the environment.

 A range of Arduino modules available including Arduino Uno, Arduino Mega,
Arduino Leonardo, Arduino Micro and many more.
 Each of them contains a microcontroller on the board that is
actually programmed and accepts the information in the form of code.
 The main code, also known as a sketch, created on the IDE platform will
ultimately generate a Hex File which is then transferred and uploaded in the
controller on the board.
 The IDE environment mainly contains two basic parts: Editor and Compiler
where former is used for writing the required code and later is used for
compiling and uploading the code into the given Arduino Module.
 This environment supports both C and C++ languages.

lesson, we’re going to give you a brief overview of
common electronic components and explain what their
functions are. You will then learn about the
relationship between voltage resistance and current

Explor
e Diagram on How Voltage – Resistance – Current
works

Explai
n VOLTAGE is the difference
in charge between two
points. CURRENT is the
rate at which charge is
flowing.
RESISTANCE is a tendency
of a material to resist
the flow of charge
(current).

Direct current voltage (DC)
Travels in a straight line and in one direction only.
Commonly produced by sources of stored energy such as batteries.
Sources of DC voltage have positive and negative terminals. Terminals establish polarity in a
circuit and polarity can be used to determine if a circuit is DC or AC.
Commonly used in battery -
powered portable equipment (autos, flashlights, cameras). Positive must be connected to
positive and negative to negative.

Alternating current voltage (AC)
Reverses direction at regular intervals.
Commonly produced by utilities via generators, where mechanical energy—rotating motion powered
by flowing water, steam, wind, or heat—is converted to electrical energy.
More common than DC voltage.
Utilities deliver AC voltage to homes and businesses where the majority of devices use AC voltage.
Some household devices, such as TVs and computers, utilize DC voltage power. They use rectifiers
(such as that chunky block in a laptop computer’s cord) to convert AC voltage and current to DC.
An electric current is a flow of electric charge. In electric circuits this charge is often carried by
moving electrons in a wire.

POLARITY – It refers to the positive
(+) and negative (-) charges that
describe the current flow in an
electrical circuit.
Polarity shows the path of the current.
Negative charges pass on the
negative path and positive charges on
positive paths.

Elaborat
e
 Voltage or potential difference is the measure of
potential energy between two points in a circuit
and is commonly referred to as its ” volt drop “.
 When a voltage source is connected to a closed
loop circuit the voltage will produce a current
flowing around the circuit.
 In DC voltage sources the symbols +ve (positive)
and −ve (negative) are used to denote the polarity
of the voltage supply.
 Voltage is measured in Volts and has the
symbol V for voltage or E for electrical energy.
 Current flow is a combination of electron flow and

 Current is the continuous and uniform flow of charge around the
circuit and is measured in Amperes or Amps and has the symbol I.
 Current is Directly Proportional to Voltage ( I ∝ V )
 The effective (rms) value of an alternating current has the same
average power loss equivalent to a direct current flowing through a
resistive element.
 Resistance is the opposition to current flowing around a circuit.
 Low values of resistance imply a conductor and high values of
resistance imply an insulator.
 Current is Inversely Proportional to Resistance ( I 1/∝ R )
 Resistance is measured in Ohms and has the Greek symbol Ω or
the letter R.

Lesson 7: Resistors
Robots have crucial role in making our jobs easily. These robots
sometimes alter human workers especially in terms of dangerous tasks.
There are many factors considered in building a robot. It is important to
know what type of resistors you are going to use to resist current flow in
your robot. A resistor is a passive two-terminal electrical component that
implements electrical resistance as a circuit element. In electronic
circuits, resistors are used to reduce current flow. A resistor color-code
served as a guide to compute the resistance based on color codes, or
find the color codes based on a resistance value in ohms.

Important Note!
While LEDs will not work when placed backwards,
you don't have to worry about whether it will be
damaged: as long as there is a series resistor of
at least 100 ohms next to it, the LED will
survive the experience!
However, using an LED without a series resistor
is a sure-fire way to kill it! (You'll see a
bright flash and it may turn dark)
Always use a resistor! A 1.0K ohm is a good place

Control Structures
Module 2 (Lesson 11)

Lesson 11:Control Structures
One of the functions of computer programming is
for communication between humans and computers or
machines. Programming is a key skill to develop for working in
robotics. Conditional statement allows performing different
computations or actions depending on whether a programmer-
specified boolean condition evaluates to true or false. There are
different conditional statements that can be used based on its
structure. Differentiating these conditional statements make us
control a robot smoothly.

Target Outcomes:

Explain
Conditional Control Structure
-The function of conditional control
structures is to make conditions or
expression that “evaluate to either true
or false. They are mostly used to
determine program flow through
if statements and while loops.

1. if CONDITIONAL STATEMENT
It executes any statement inside the brackets { } if the conditional
statement is true. If false, the program skips over the statement.

2. else CONDITIONAL STATEMENT
An if statement can have an else clause which handles what should be done
if the if statement is not true.

3. while LOOP STATEMENT
A while statement is just like an if statement except it continues to repeat
a block of code (a block of code is what is within the curly braces) as long
as the condition is true.

4. If...else if CONDITIONAL STATEMENT

5. for LOOP STATEMENT

Serial Monitor

Lesson 12:Serial Monitor
Today, robots are everywhere. It has essential role in making our lives
more convenient. Robots replaced some people working on
dangerous tasks. These robots receive commands from the
programmers to do a certain task using computers and a software.
Communication between robots and humans is important. Robots
cannot understand the language we are using that is why
programming languages are developed. These source codes
(commands) are converted into machine codes that can only
understand by the computers. Serial Monitor is used for
communication between the Arduino board and a computer or other
devices. Its job is to allow you to both send messages from your
computer to an Arduino board (over USB) and also to
receive messages from the Arduino.

switch that is very important in allowing and stopping it from
working. This part of robots connects and breaks the flow of
electricity. Electronic switches are used to perform all logical
functions.

Robots can be able to do its jobs because of energy came from
its power supply. This power supply delivered right amount of
voltage needed by robots to move. Without a power supply,
robots will not function. The voltage came from the power
supply can be divided by potentiometer. This device is
powerful in dividing amount of voltages that flows in the electric
circuit. The potentiometer is used in radio and television (TV)
receiver for volume control, tone control and linearity control
and even in robots too.

contact that forms an adjustable voltage
divider.
POTENTIOMETER ELECTRONIC SYMBOL
It is essentially a voltage divider used
for measuring electric potential
(voltage); the component is an
implementation of the same principle,
hence its name. Potentiometers are
commonly used to control electrical
devices such as volume controls on audio

USES OF POTENTIOMETER
1. Rheostat → To use the potentiometer as a rheostat, only
two pins are used: one outside pin and the center pin.
If we have a 10kΩ potentiometer, it means that the maximum
resistance of the variable resistor is 10kΩ and the minimum
is 0Ω. This means that by changing the wiper position, you
get a value between 0Ω and 10kΩ.

USES OF POTENTIOMETER
2. Potentiometers → can be used as voltage dividers. To use
the potentiometer as a voltage divider, all the three pins
are connected. One of the outer pins is connected to the
GND, the other to VCC and the middle pin is the voltage
output.
The voltage divider is used to turn a large voltage into a
smaller one.

Types of Potentiometer
Rotary is the most common of variable resistors or
potentiometers.

Types of Potentiometer

n
Potentiometer
When using a potentiometer, connections are made
to both ends as well as the wiper, as shown. The
position of the wiper then provides an
appropriate output signal (pin 2) which will vary
between the voltage level applied to one end of
the resistive track (pin 1) and that at the other
(pin 3).
The potentiometer is a three-wire resistive
device that acts as a voltage divider producing a
continuously variable voltage output signal which
is proportional to the physical position of the
wiper along the track.

Lesson17:Buzzer
TWO KINDS OF BUZZER
An active buzzer will generate a tone using an
internal oscillator, so all that is needed is
a DC voltage. A passive buzzer requires an AC
signal to make a sound. It is like an
electromagnetic speaker, where a changing
input signal produces the sound, rather than
producing a tone automatically.
Passive buzzers do not differentiate
positive and negative polarity while active
buzzers do. There is a little similarity

7-Segment Display

Lesson19: 7-Segment Display
Device like digital clock shows the actual number of time. It is
easy to read especially for those people who have blurry eyes
and those children who don’t know yet how to read an analog
clock. But what makes it display numbers? This kind of clock
uses a seven-segment display or seven-segment indicator. It is a
form of electronic display device for displaying decimal numerals
that is an alternative to the more complex dot matrix displays. It
consists of 8 LEDs connected in parallel that can be lit in
different combinations to display the numbers (0, 1, 2, 3, 4, 5, 7,
8, 9, A, B, C, D, E, F, etc.). It is also widely used in digital clocks,
basic calculators and so on.

Target Outcomes:
able to:
 Identify the circuit diagram of a 7-segment
display.
 Explain the use of a 7-segment display

Human Numbers
The class will be grouped with ten
members. Each group will receive a number
sticker (1-10). The number signifies
their position in line.
Procedure:
Form a straight line. Hold each other’s’
hands.
As the teacher flash a number, each group
will imitate this number. (take note that
each group should not be allowed to let
go of the members’ hands.)
The first group to finish the activity

Explore
Group the class into four. Each group should
be given seven (7) hexagonal shapes. Using
these shapes, ask them to form a number that
will be flash on the screen. The first group
to finish their work should be the winner.

Explain

The position of light shown by 7-segment display are represents by
letters. In arduino code, LED lights on expressed by a number
“0”while LED lights off are expressed by a number “1”.
Identify what number is shown using 1’s
and 0’s codes.
1)0 0 0 0 0 0 1 – 0 (number 1 is done for
you)
2)0 0 0 0 1 0 0 –
3)1 0 0 1 1 1 1 –
4)1 0 0 1 1 0 0 –
5)0 0 1 0 0 1 0 –
6)0 1 0 0 0 0 0 –

Project: Working
with 7-Segment
Display

Lesson 20: Project: Working with 7-Segment Display
Seven-segment display is an electronic display device for
displaying decimal numerals. It is widely used in displaying
numbers and some letters electronically. The segment (LED)
display is denoted by letters A to G and the eighth segment
called “Decimal Point”. It is denoted by DP and is used for
the display of non-integer numbers. Working with 7-Segment
Display is slightly complicated especially in terms of coding
numbers and operating in basic electronics but learning with this
device is exciting. Using seven –segment display, you can
present numbers in your programmed calculator or even in
a simple score board.

Target Outcomes:
able to:
 Learn how to display, code numbers, and operate a
segment in basic electronics.

Activity
Group the class with four members. Each members should prepare 1/8 size
illustration board.
Ask the learners to write the set of letters that denotes the LED
(segments) of the following numbers. Let each group work for each in 1
minute.

Explore
The class will be grouped into four. Make a reference table for displaying digits in 7-segment
display. Students will post their work on the board for checking.
The first digit should be done for the learners.
