Surface Disinfection Using a Mobile Robot

ABSTRACT

The emergence of COVID-19 pandemic led to an increase in establishing methods of sterilization and prevention, and also in the searching for sterilization methods at the lowest cost and most effective in eliminating viruses. Robots are widely used in many fields including the sterilization to reduce the risk to human life. This work presents a design and implementation of robot for automatic surface disinfecting using Ultraviolet (UV) lights. Arduino UNO R3 is used as micro controller to control the movement of the mobile robot and three ultrasonic sensor which used to avoid robot collision with obstacles. UV lights are used in the sterilization processes of surfaces, air and water, as it ruptures the DNA of bacteria or viruses and thus prevents it from reproduce. Eight UV lights are used in this research work which are fixed around the mobile robot. The results showed the low cost with robot using for surface disinfecting can be obtained with using simple sensors and actuators components and UV lights, as well as being safer for humans than using chemical disinfectants. © 2022 IEEE.
