Abstract
Ultra violet (UV) light is used for the purpose of disinfection or sterilization of rooms and surfaces. UV-C is employed as it has germicidal properties, in particular - bacteria and viruses, but it is detrimental to human-beings as well. So, for the purpose of disinfection without human interference, a UV Robot has been designed and implemented that follows a pre-defined path. It was equipped with three 20W UV lamps which radiates light in all directions. Given that UV light can be dangerous to humans, an embedded system based on Arduino along with PIR sensors are employed on top of the robot that detects human or animal’s motion and presence. So, one of the effective ways to avoid getting infected with SARS-COV-2 (Corona virus) is by sterilizing rooms using UV robot.
Highlights
The ultimate aim of disinfection and sterilization is to inactivate or eliminate microorganisms in order to avoid the spread of airborne diseases and infections
A cost efficient and effective Ultra violet (UV) robot has been designed to limit the spread of bacteria and viruses, which goes along the given path [11, 16] and has the capacity to reach the inaccessible areas for effective disinfection
This paper examines the sterilization effects of UV-LED and proves that UV-LED is capable of sterilizing morbific bacteria [3]
Summary
The ultimate aim of disinfection and sterilization is to inactivate or eliminate microorganisms in order to avoid the spread of airborne diseases and infections. Low pressure mercury lamps which are a cheaper way to generate disinfecting UV light, can be used for this purpose [7]. It is economical and environment-friendly to use UV light due to it’s high replacement cycle. A cost efficient and effective UV robot has been designed to limit the spread of bacteria and viruses, which goes along the given path [11, 16] and has the capacity to reach the inaccessible areas for effective disinfection. Subjection of skin to Ultra Violet radiation results in cell damage, tissue damage, DNA damage and skin cancers [9, 10]. The robot is designed in such a way that it follows a pre-defined path [12, 13]
