Disinfecting Robot with Ultraviolet Lights

Service robots are increasingly present in all fields of Medicine. The aim of the present work is to contribute in the fight against the spread of COVID-19, a novel human coronavirus in hospitals, public transport, airlines and any enclosed areas. In this study, we have adopted the physical disinfection method by using UV. Use of these service robots reduces the risk of infection, cost of traditional cleaning and disinfection, and most importantly acquires confidence and security in medical facilities. For the purpose of disinfection without human interference, a UV-ROBOT has been designed and implemented that follows a predefined path. It was equipped with 20watt UV lamps which radiated light in all directions. Given that UV light can be dangerous to human life, an embedded system based on 8051 controller along with PIR sensors are employed on top and bottom of the robot that detects human or any objects motion and presence. Robot follow Bluetooth commands, So one effective way to avoid getting infected with coronavirus is by sterilizing rooms using a UV robot.
