Ultravoilet Sterilization Disinfectant Robot for Combating the COVID-19 Pandemic

Ultraviolet (UV) sterilization technology is used to aid in reduction of microorganisms that may remain on the surfaces after a standard cleaning to the minimum number. A UV bot is used for sanitization in an operating or a patient room. UV bot has three 19.3-W of UV lamps mounted on top of the UV bot platform covering 360-degree direction. UV bot employed in our project uses embedded system based on Arduino ATmega328 to aid in navigation to avoid obstacles. In addition, it has been tested the effectiveness of eliminating staphylococcus Aureus bacteria sample plates located 35 cm away from UV bot to be within 8 s after UV-light exposure.
