Block Diagram Abstract – This main aim of the project is to monitor social distancing in the queue which is important during the COVID19 pandemic. Due to the high infection rate of COVID-19, it is responsible for loss of life around the world. The robot can help to monitor social distancing to reduce the frequency of people coming into contact with others in the queue. We are not suitable to monitor 24×7 at each queue and aware the humans about social distancing violations. With the help of mobile robot we can detect human pairs and alert them where social distancing norm is not followed in the queue.
1. INTRODUCTION Social distancing is one of the best way to limit the spreading of COVID-19 in the queue. The precaution of maintaining social distancing norms in the queue has become an indispensable precaution to slow down the transmission of COVID-19. Usually we see long queues for hours every day in the banks, public offices, public places, malls, theatres etc. The queues are becoming main hotspot for spreading Covid-19 among the people. To maintain and monitoring the social distancing in the queues, we hereby design a mobile robot i.e. social distance monitoring robot. To drive the robot, we uses 4 wheel design system. With IR sensor the robot makes use of a line following principle to constantly move along with the queue. It also uses IR sensor for detecting distance between human pair in a queue. It any 2 individuals or in human pair are found having distance less than 1 meter between them, the robot instantly sounds a warning and alert them about the violation. Also it gives alerts about these violations by displaying message on LCD screen and aware the people who are not maintain social distancing.
Fig -1 Block diagram of social distance monitoring robot In the block diagram of social distance monitoring robot, microcontroller is used to connect different components and collects information from the IR sensor and gives output according to program which is burn in it. The robot is equipped IR sensor to detect social distancing in the queues. For movement of the robot, we uses L293D motor driver to drive 4 DC motors. LCD screen displays the welcome message and alerts message of “keep distance” of these violations along with a queue. In any queue, 2 individuals are found having less than 1 meter distance between them, the voice feedback module alerts them with help of speaker. This power supply converts 230V ac into +5 volt dc and +12 volts dc. +5 volts is required for Microcontroller, IR sensor & LCD display and + 12 Volts for motor driver circuit is required.
