 Automatic floor cleaner is an electronics home appliance
which work on two modes automatic and manual.
 It performs two operation sweeping and mopping.
 It can be use in crowed place like bus stands, railway
station, airports etc.

Idea

4
 Most of the people are working and they did not have
enough time to clean.
 From time to time technology come up and need to
upgrade for easier human task.
 Most of us usually using a hand controlled vacuum for
cleaning .Moreover, most of vacuum robots in the market
are expensive and may be large in size

5
 A new service robot designed for cleaning tasks in home
environments is introduced.
 System has three subsystems: electrical, software and
mechanical.
 Of which microcontroller, sensors (opponent and light)
and motor are the electrical and mechanical subsystems
respectively & the software subsystem is the brain of the
robot.

 The cleaning robot uses a microcontroller to detect
obstacles and manipulates its direction as per the inputs.
 It is programmed to accept inputs to sense obstacles
around it and control the robot to avoid any collisions.
 In case of an obstacle, or a potential collision, the
microcontroller controls the wheels of the robot by a
motor driver to avoid collision. The vacuum cleaner at the
bottom of the robot performs the cleaning process.

History

7
 The first type of such system relies on various sensors and
artificial intelligence in order to systematically move the
floor cleaner across the floor.
 The sensors detect objects and other obstructions and the
artificial intelligence system determines the course of
action of the device with respect to the object or
obstruction.

Components Used

8
 PLASTIC BOX
 MOPPING PRODUCT
 AIR SECTION
 ARDUINO UNO
 2 BO MOTOR
 MOTOR DRIVER
 IR SENSOR
 CURRENT BATTERY (Li-ion)
 BATTERY HOLDER
 WHEELS
 VACCUM MOTOR
 CONNECTING CABLES

FEATURES

9
 Small size so it will enter a small area.
 Low cost, cost of body, three sensors, microcontroller and
one motors driver.
 As it is an automatic robot so we just have to on the
power switch and the robot start cleaning floor.

Sensors Used

10
Two types of sensors are used:
IR-SENSOR ULTRASONIC SENSOR

CODE

#include <AFMotor.h>
AF_DCMotor motor1(1);// Initialize motor1 on M1 port of L293D
AF_DCMotor motor2(2);// Initialize motor2 on M2 port of L293D
const int triggerPin1 = 4;// Define trigger pin of ultrasonic sensor 1
const int echoPin1 = 5; // Define echo pin of ultrasonic sensor 1
const int triggerPin2 = 6; // Define trigger pin of ultrasonic sensor 2
const int echoPin2 = 7;// Define echo pin of ultrasonic sensor 2
const int triggerPin3 = 8;// Define trigger pin of ultrasonic sensor 3
const int echoPin3 = 9;// Define echo pin of ultrasonic sensor 3
const int irSensorPin = 13;// Define IR sensor pin
void setup() {
Serial.begin(9600);// Initialize serial communication at 9600 baud
pinMode(triggerPin1, OUTPUT); // Set trigger pin of ultrasonic sensor 1 as output
pinMode(echoPin1, INPUT); // Set echo pin of ultrasonic sensor 1 as input
pinMode(triggerPin2, OUTPUT);// Set trigger pin of ultrasonic sensor 2 as output
pinMode(echoPin2, INPUT); // Set echo pin of ultrasonic sensor 2 as input
pinMode(triggerPin3, OUTPUT);// Set trigger pin of ultrasonic sensor 3 as output

pinMode(irSensorPin, INPUT); // Set IR sensor pin as input
}
void loop() {
// Measure distance from ultrasonic sensor 1
digitalWrite(triggerPin1, LOW);
delayMicroseconds(2);
digitalWrite(triggerPin1, HIGH);
long duration1 = pulseIn(echoPin1, HIGH);
int distance3 = duration1 * 0.034 / 2;

// Check if robot is on ground
int irSensorValue = digitalRead(irSensorPin);
Serial.print(irSensorValue);
// Determine motor speed and direction based on sensor readings
if (distance2 > 10 && irSensorValue == 0) {
// Move forward
motor1.setSpeed(150);

motor1.run(FORWARD);
}
else{
if(distance3>distance1 && irSensorValue == 0){
motor1.run(BACKWARD);
delay(500);
// Turn left
Serial.print("left");
}else if(distance1>distance3 && irSensorValue == 0){
delay(500);

// Turn right
Serial.print("right");
}else if(irSensorValue == 1){
motor1.setSpeed(0);
motor2.setSpeed(0);
motor1.run(RELEASE);
}else{
motor1.setSpeed(0);
motor2.setSpeed(0);
}
}

Serial.print("distance3: ");
Serial.print(distance3);
Serial.print(" Distance2: ");
Serial.print(" distance1: ");
Serial.print(" On ground: ");
Serial.println(irSensorValue);
delay(100);
}

Application

18
 This is very much helpful for elderly people as well as for
those who are unable to walk either due to physical
disabilities or due to accidents.
 Another major use of our project is that we can turn off
the operating devices all together at one shot by just
pressing the power button.

Advantages
29-May-24
19
 Time saving as it is operated automatically.
 All the devices are self controllable.
 More secure as there is no direct contact with the
appliances.
 Very effective for household needs.
 Eco-friendly and produces less noise pollution.
 No need of any type of remote control.

Conclusion

20
 The presentation shows a better and simple approach to
provide an overview of design of a simple robotic
cleaners control design using gadgets and instruments
easily available in Indian market.
 This robot is specially made on the basis of modern
technology. It can work automatically and manually.
 It has the feature of the scheduling and it can auto drain
itself.
