Abstract: We all know that covid-19 situations effects our lives a lot in recent days. During those current situation, social
distancing plays crucial role because it helps limit the increment of Covid cases due to the perceived distance between people
who spread the disease. At present, there is no way to place one person in each row in a queue or any place to monitor social
distancing violations. Public places like shopping centres, cinema theatres, Parks and schools, government offices and tourist
places etc. Many peoples in queues for several hours a day. To monitor the social distance in variouspublicplacesinqueue, we
want to develop a social distance monitoring robot based on IOT. The moving robot capture the visuals of people (which was
controlled by a person) as they are in certain distance or not, calculated with the help of various sensors and givestheanalysis
to the controlled persons.
1.Introduction
The COVID19 effect has started worldwide andturnsinto a bighealthissueandstarted destroyingnotonlyeconomical systems
but also free life of people all over the world their health and wealth. In that situation manycountriesstartedavoidingphysical
contact with people and started using machines and robots to control these hazard. Many governments and countries got
alerted on this situation to take social distancing on to the people in rushed areas as well as in many crucial administrative
places. This will monitor the norms and actions of people, that they were followingthe rulesornotandtakingnecessarynorms
on people to follow the rules for prevent this situation.
We have to take our step forward from our side to maintain such rules for reduces the covid. So, we are also going to make the
mechanically controllable device that will monitor the actions and precautions taken by the people in public places and also
giving the report and index of the report as feedback to us. In deeply it observes the distance between the people in a queue as
they are strictly following the social distancing and have they properly masked or not which was analysed by the devices
connected to the moving robot, which are fixed to the four wheel moving robot which were attached on to thatrobotasonIOT
system. This IOT system helps to send the valuable data to us as it measures the distance of people and send it through WiFi
system fixed on the robot. And through that data we will take necessary action and controllable measures.
2.Required Hardware components
Ultrasonic sensor: It is a measuring device that gives the value ofdistancebetweentwo peoplebyemittingtheultrasonicwaves
and changing them into electrical signals for the sake of easy calculationtosystem.Ultrasonicwaves arereflect back whenever
the waves hit an object by the use of transmission and receiving ends in it. the distance on the receiving end by decoding the
sonic signals to electric signals.
DC Motor: Electrical energy to mechanical energy conversion is the motor definition. Especially the DC motorhasinputsource
is DC current that will helps in drive the conversion of energy by using electric DC current.

It helps to the moment of the robot by the principle given above the definition.
Buzzer: This is the component that makes a sound when a electric signal is passed to it as a input signal to make that sound.
This component role in this project to give a alert signal to the surroundings.
IC: It is the component that has many passive components integrated on a single silicon chip that has inbuilt resistor, capacitor
etc.. which is well knowned component in many electronic circuits and systems.
Transistors: Voltage or current flow regulation is called transistor. It also acts as switch in circuitsforcertaininput parameters
or source
Resistors: Opposing of electrons is the definition of ressistor . It connects in circuit like to the anode of led for resisting the
enough supply to led.
Capacitor: it is the component for the efficient of time producing the potential difference that it stores the electric charge in it.

Diode : Allowing the flow of current in single direction through it.
LED: light emitting diode that emits the light whenever the energy of electric charge flows through it. In manycircuitsitactsas
output to identify the outcome of output.
PCB: In any circuit designing Printed circuit board is the main or important component. We connect any many electronic
components on it and we connect on the printed schematic lines which make electrically connected.
Wires and connectors: In any electric or electronic circuits wires plays a key role in making connections also as bypassing the
components supply.

3. SOFTWARE SPECIFICATIONS
Raspberry pi: It is a computer replaced on a board that also canbeconnectedwithmouseandkeyboard.wecancommunicateit
with linux to make various designing and projects.
We can use the linux to program to communicate and to work with our iot projects.
It has OS, Ram, CPU, and also capable of GPIO that we can connect various electronic components that to control via those to
make in use various internet of things designs and projects.
Here we are connecting various electronic devices to this like, camera, wifi module thatwill sensevariousvisuals,andsendthe
analysed and recorded videos to the destination through the internet connected to the board.
4. ROBOT CONCEPT
It is a moving car type robot in which it has various electronic components and devices like , power source, camera, ultrasonic
sensor, wheels and motors as well as wifi model together form the robot which we had used for this project.
4.1 INFO ABOUT THE MOVING ROBOT CONCEPT:
It’s a total different concept which we heard about a robot, that here the robotisworkson theconceptoffollowing a linewhich
was sensitizing by the IR leds that follows the input of black and white lines.
Here the IR sensor controls the moment of the motor left and right as well as front and back.
The sensors makes the robot move as, the black and white lines which were the references of the IR sensor that makes the
robot moves left if the black line sensed by right sensor else right if the black line sensed on right.

As per the diagram shown above IR sensor transmission and receiving the sensed black and white lines will judgethemoment
of robot. This makes the robot moment to record the surrounding visuals.
4.2 WORKING OF THE PROJECT:
As we mentioned the components used for thus project, we have the movingrobotthatmovestowardsthe queuefortakingthe
social distancing visual by using camera fixed on the robot.
Measure the obstacle distance by signal that got by sonic sensor .
This sensor has transmitter that send the signals towards the free space, whenever the transmitted signalshitsobjectthenthe
signal got recived by receiver and then it will calculated it as shown in below.

4.3 ARCHITECTURE:
This architecture gives the information about our project that it has two units as:
Two blocks under social distancing monitoring units as shown in the diagram blocks. Those are Rfid, application, sensors,
camera, robot system.
Advantages
1. Accurate automation system
2. Very less errors
3. Wireless communication helps easy tracking
4. Raspberry pi gives less complexity design
5. More reliable in working
6. Easy replacement of in case of damaged components

Disadvantages
1. Continuation internet connection required
2. Charged battery required for full time working
CONCLUSION:
Prevention is better than cure, so we have to fought against such a dangerous virusinfuture,sothisdevicecancontrol andgive
the preventive steps and cautions to follow the rules to fought against the covid virus on the implementation of social
distancing in queue not only in public places but also in various places
So we have to use present day technology like robots, for getting better results in this situation
So our project will definitely helps to maintain such preventive steps andtakeforward thedisciplineincrowdaswell aspeople
where the social distancing is more efficiently required.
