2. WHY? An automatic floor cleaner
2
More and more buildings are now well planned
HUMAN Resource are very important
We are meant for more creative type of works
Will save a huge amount of time and resources
3. The aim of this work is to develop and modernized process for
cleaning the floor. Floor cleaning system is very much useful in
places like hospitals, houses, auditorium, shops, computer
centres etc. The time taken for cleaning is very less and the
maintenance cost is also less. It also reduces man power
requirement. The size of the machine is also portable, so we
can transfer from one place to another place very easily. The
floor cleaning machine is simple, modern house holding
device; even children can also operate it easily with safety. In
present time of pandemic (covid-19) where our cleanliness is
being questioned , this automatic floor cleaner prototype is a
good answer to those questions. Our health workers to have
been facing plithora of problems regarding cleanliness.

OBJECTIVE
5. Main components are
ARDUINO UNO BOARD
TYRES
MOTOR DRIVERS (10A 12-36V)
SIMPLE UNIVERSAL MOTOR
CLEANING BRUSHES
MOTORS (10 A 36V)
SD CARD AND SD CARD READER
WATER TANKS
MAIN FRAME
5
6. THE ARDUINO (UNO)
OPEN SOURCE
COST RS 450
RELIABLE
SOFTWARE IS ALSO OPEN SOURCE
It is the brain of our machine it runs the code written by us
and hence directs the functioning of motors ,sensors etc.
6
7. MOTOR DRIVER
We are using smartdriver-10
Its cost is RS 800 (Negotiable)
It is mainly used to give the right voltage to
the various components of the machine e.g
arduino (5v), motors (12-36v) etc
7
8. BLUETOOTH MODULE
It is used to connect the arduino to our app so
that we can run
our machine manually for setting the initial
path
Once it is disconnected then the machine will
run itself on the
told path.
Its cost is RS 240 (Negotiable)
It takes 5v battery supply
8
9. SD CARD MODULE
Since we are storing the the path for the
machine to then follow it autonomously
so we need a SD card to store all that data
This module enables us to connect the
micro SD card to the arduino .
Cost RS 75 (Negotiable)

10. RELAY
Relay switch automatically breaks the circuit.
A relay is an electrically operated switch that
can be turned on or off by giving it an input
signal.
10
11. Heavy duty DC motor
Needs 12-20 V supply and 5A or
more current
Used in rear wheels to move the machine.
11
DC Motor
14. It works by storing the commands that we give
to the arduino during the setup and the
duration till which those commands are given.
Then it stores those commands on an SD card.
When we have decided the general path it then
runs those commands from the SD card thus
successfully retracing it path
A detailed working is given in the report.

22. Friction
Friction is the force resisting the relative motion of solid
surfaces, fluid layers, and material elements which are
contact with each other.
Types of Friction: There are several types of friction like
Static Friction
Kinetic Friction
Fluid Friction
Rolling Friction

23. CENTRE OF MASS
Centre of mass is sometimes also called as the
balance point. It is the unique point where the
weighted relative position of distributed mass
sums to zero. It is a hypothetical point where the
whole mass of the body is supposed to be
concentrated.

24. TORQUE
Torque is the rotational equivalent of the linear force. This
originated with the studies by the Archimedes of the usage of
levers. It can also be considered as the twist around the
specific axis. It is the product of the magnitude of the force
and the perpendicular distance of the line of action of force
from the axis of rotation.

26. ACKNOWLEDGEMENT
Special thanks to our mechanical engineering teachers
who taught us the necessary concepts and provided us
with the required experience that enabled us to make this
project.
The mechanical engineering class taught us a very
important concept that curiosity is the mother of learning.
Special thanks to Arpita Maam for helping us grind on our
concepts over mechanics.
