ABSTRACT

During the current pandemic, social distancing is crucial because it helps limit the development of Covid due to the perceived distance between people who spread the disease. Currently, there is no option to place one person in each row 24/7 to monitor social distancing violations. Banks, authorities, shopping centers, schools, theatres, etc. There are often long queues for several hours a day. To verify the queuing social distance, we want to develop a social distance robot

INTRODUCTION

Since the end of 2019, the COVID19 pandemic has spread globally and may become a major health and safety issue for communities, health workers, and health systems around the world [1]. During the pandemic, there are plans to use robots around the world to improve patient care and reduce the burden on the medical system. People may have to coexist with the virus for a long time. In fact, one of the most important effective measures to control the Maintaining social distancing performs a important function in stopping the unfold of infectious diseases. Diseases much like COVID19. spread of the coronavirus is to maintain social distancing. By minimizing close physical contact between people, we reduce the chance of contracting the virus and spreading it throughout the community. Observing the norms of social distancing between people has become an important measure to prevent the spread of COVID19.

Our goal is to introduce a unique method for mechanically observing a pair of people, in a crowded environment that does not comply with social distancing restrictions. Relative to the distance of two meters between them.

 HARDWARE COMPONENTS REQUIRED Ultrasonic Sensors:

ultrasonic sensor :-is a virtual device that measures the gap to a goal via way of means of emitting ultrasonic waves and changing the pondered sound into electric signals. Ultrasound travels quicker than audible sounds (that is, sounds that may be heard via way of means of humans). Ultrasonic sensors have simple components: transmitter (to ship sound via the piezoelectric crystal) and receiver (to come across sound after it enters and leaves an object). Figure 1 shows the ultrasonics sensor. 

DC Motor: When a current-sporting conductor is located in a magnetic area, it transmits torque and hasan inclination to move, that is, whilst the magnetic area and the electrical area interact, mechanical pressure is generated. According to this principle. This is known as a motion action. It is as depicted in figure 2. A DC motor is any form of rotating motor that converts DC electric power into mechanical power

Buzzer: A buzzer may be a valid sign instrument, which is probably mechanical, mechanical tool or piezoelectric. Typical makes use of for buzzers are alarms, timers, and affirmation of person input, collectively with mouse clicks or keystrokes. Figure 3 shows the buzzer

Resistors: The foremost feature of resistors in a circuit is to manipulate the float of modern-day to different components. Figure 6 shows the resistor. Take an LED (light) for example. If an excessive amount of modernday flows thru an LED it's far destroyed. So a resistor is used to restrict the modern-day.

IC: An integrated circuit (IC) is an electronic device that contains various diodes, transistors, resistors, and/or capacitors made from wafers or crystals of semiconductor materials. Integrated circuits are commonly used in robots and their control.

Capacitor: It is an electronic component whose function is to store electrical charges and then release them. A capacitor is a component that stores charge or energy when a voltage is applied as depicted in figure 7. Compared with batteries that generate new electrons through chemical reactions, capacitors behave exactly like electrons. Repositories, don't create them.

Transistors: One of the foremost basic functions of an electronic transistor is to act as associate electronic switch. It is as shown in figure 5. We want the transistor to allow a small amount of current to flow from the collector to the emitter when it is "off," and to let as much current as possible through it. May be "on"

Diode: A diode is a tool that lets in current to waft in a single path however now no longer the other. This is accomplished with the aid of using the integrated electric powered field. Diodes are two-terminal gadgets that behavior power withinside an identical path. Figure 8 shows the diodes

III. SOFTWARE SPECIFICATION Raspberry Pi:

The Raspberry Pi board is a small computer (approximately the scale of a credit score card) that may without difficulty hook up with the Internet and engage with many hardware components. Raspberry Pi is more and more utilized in robotics projects. Figure 12 shows the structure of Raspberry Pi

 CONCLUSION Since individuals will unfold the virus before they grasp they're sick, it's vital to stay a minimum of six feet faraway from others though you or they are not showing symptoms. Social distance is especially important for people who are at increased risk of overexposure to covid19. In this tail tracking and social distance robot, we can calculate the distance between people and limit the development of viral diseases, especially where social distance is an important factor. Used in all queues of banks, government agencies, shopping malls, theatres, etc. In the future, we can automatically apply for the future with the help of machine learning, computer vision, thermal imaging, and ultrasound technology.
