In this project we are creating a prototype of disinfectant robot using application such as Ultra Violet-C Ray, Android Bluetooth and Arduino Nano. During this Covid-19 pandemic which has become a major threat to human life, application such as disinfectant robot is being very useful. This disinfectant robot can be use in multiple application and place such as hospital, hotel, movie theatre, shopping mall, office, other work area, etc. This application is majorly used on non-living material instead of liquid medium which has a chance of damaging electronic application. The robot helps in less human contact which help in less spread of infection. Efficiency of this disinfectant robot is 99.9% killing of Bacteria and Virus. © 2023 Elsevier B.V., All rights reserved.
