Abstract—Since 2019, coronavirus has impacted all aspects of humans and become one of the most serious pandemics in history. To prevent the spread of virus transmission in public, cleaning and disinfection with the support of technology are effective ways worldwide. The paper focuses on the design and development of a multifunctional autonomous mobile disinfection robot, namely MEM-Bot. The MEM-Bot integrates robust and well-developed technologies such as remote control, auto-navigation in a mobile platform with a biology/chemical solution to sanitization and disinfection effectively. The MEM-Bot consists of 8 UCV lamps with 240 W radiation with no restriction emitting area, a 360o spinning detergent system, a pair of retractable arms equipped with mist nozzles to cover the lower area of spraying, and a floor-cleaning module. The overall disinfection zone is cylindrical with a radius of 1 meter and a height of 3 meters. Fabricated at a much lower cost than commercialized robots, MEM-Bot has been rapidly deployed and tested at the Phenikaa University campus zone for months. The MEM-Bot is a potential solution for developing countries against the COVID-19.
