The student Karina Goff describes building a homemade fan robot for a school project. The fan robot is constructed from simple materials like cardboard, a CD, cardboard tubes, a toy motor, and a USB cable. It has 8 cardboard blade sections cut from a circle and bent at 45 degrees. The blades are attached to a motor wired to a USB cable, which provides power when connected to a computer or charger. The document outlines the step-by-step process for constructing the fan robot, from gathering materials to connecting the motor and blades. The conclusion states that technological advances can be built from simple materials and small projects.

2. Introduction/Description of the setting
In this project we are going to learn or explain how to make a homemade
robot. When we hear the word robot, the first thing that comes to mind are
those impressive metallic forms, humanoid or not, with thousands of functions
and super modern that are sometimes considered intelligent and that we have
seen in science fiction movies or video games, and It makes us think that
making an easy homemade robot is an arduous task, impossible for anyone
who is not an expert in technology or an advanced engineer, but the truth is
that it can be something as simple as making a homemade fan.

3. Research question and objectives
What robot will we do?
We will make the homemade fan
What are the materials we will need?
-Thin cardboard plate, approximately 20 × 40 centimeters.
-Old unusable CD.
-Generic USB cable
-Cardboard tubes, it can be a toilet paper roll.
-A motor from some old toy, small like a cart or a walking
doll, so that the
-USB power is sufficient to mobilize it.
-Scissors or a sharp object
-Silicone
-Marker
How to make a fan step by step
To start making your homemade fan, place the CD on the
thin cardboard plate and draw its circular outline twice, one
of the circles includes the hole in the center and the other
does not. Cut the circle that does not have the hole marked
and keep it.
On the other hand, to the circle with the drawing of the hole,
draw another circle inside a radius of approximately one and
a half centimeter and mark transverse lines to the outside of
the cardboard wheel, dividing it into eight sections of the
same size. Make sure they are the same as they will be the
blades of your home fan.

4. Cut the circle and cut the blades, leaving the central circles
of the cardboard uncut, you should have a figure like a
flower, which will be the blades of the home fan.
Lightly bend each of the cut sections about 45 degrees to
give it the blade shape your home fan needs. To keep the
blades in that position, put silicone on each inner edge to
give it hardness.
Keep the cardboard blades, while they dry take the USB
cable. Separate the plastic cover from the cable at the
smallest end, which is usually used for connection to the
mobile, and cut its tip to leave the four small cables free.
You will see that the cables have four different colors, keep
only the red and black cable, the others remove them will not
be necessary.
To assemble the base of your homemade fan, take the
cardboard tubes and glue them to their edges with silicone to
obtain a cardboard tube twice as long. Now make a cut as a
hole about a centimeter in diameter in the bottom edge of the
double tube.
Once the tube is well glued, you must glue it to the center of
the first cardboard circle that you cut, in order to create a
firm base that does not wobble when operating.
Insert the USB cable through the hole in the cardboard tube
attached to the base with the USB part on the side of the base
and the cables on top. You already have the base and the
blades of your home fan, so now we will mount the power
source that allows its movement.
Cut a cardboard circle the same diameter as the cardboard
tube and make a large hole in the center where the USB
cable can pass. Glue it over the top of the cardboard tube by
passing the cable through the hole so that it is on the outside.

5. To finish making a homemade fan, strip half of the red and
black wires sticking out of the cardboard base and connect
them to the toy motor. Glue the motor to the base. Once the
motor is firmly on the base, take your cardboard blades and
insert them through the center to the motor shaft, gluing it
with plenty of silicone. Let it dry and voila, connect the end
of the USB cable directly to a computer or an electric power
adapter and enjoy the breeze from your home fan.

6. Conclusion
With this work we were able to conclude that technological
advances are currently growing, based simply on simple
things, such as, for example, we were able to notice the
materials used for this project, they are the easiest to get, and
it is precisely from small things that we get to things large.

7. Special Thanks
Thank you very much for these months of hard work, which helped
us a lot, it does not progress until we can learn, thank you for all the
opportunities that you give each of my colleagues and me. Thank
you so much for everything. Blessings for you and your family.
