The proposed work elaborates the necessity of sterilisation especially during COVID-19 period. In this chapter, we will discuss about the development and construction of an 'Arduino-based robot for the purification of COVID-19 using far UVC light'. Throughout history, the outgrowing technology has solved major problems. Technology has made everything possible, from making knowledge more available to more people and bringing group of people associated, to making our planet cleaner and even saving lives. But the current circumstance of COVID-19 is threat to human lives as there are high chances of getting sick in no time, so in order to fight with this novel virus. There is necessity to keep our surroundings clean and tidy. Cleanliness is the most important factor to keep ourselves away from diseases. The objective of the current work is to discuss various inventions made during the pandemic scenario and to contribute to the battle against COVID-19 propagation, a novel human corona virus in hospitals, public transports, airlines, and any enclosed areas with an approach, which is a basically a bot named 'Arduino-based robot' which uses ultraviolet (UV) sterilisation method to kill and eliminate all the germs and viruses present in the surroundings and sanitises the entire surroundings by cleaning and disinfecting the environment. Far-UVC (ultraviolet C) radiation has a wavelength range of 207-222 nm. The decontaminating efficiency of far UVC light was previously tested by exposing bacteria that were irradiated on a surface or in suspension. We have developed a UV-based sterilisation method that uses single-wavelength far-UVC light produced by filtered exclaims to selectively inactivate microorganisms while causing no biological damage to exposed cells and tissues. The method is based on biophysical principles, as far-UVC light can penetrate and thus inactivate bacteria and viruses with dimensions in micrometre or smaller, while far-UVC light cannot penetrate even the outer dead-cell layers of human skin, nor the outer tear layer of an eye, due to its high absorbance in biological materials. The far-UVC lamp plays a major role in a disinfection robot. This bot will disinfect the virus and clean the areas; it will travel autonomously and sterilise the areas without the need for human intervention. In the discussion section, a demonstration of the bot's implementation and presentation was shown. This robot can also be used as a vacuum cleaner, eliminating the need for and expense of cleaning by humans.
