With respect to pandemics, restaurants, stadiums, cafeterias, and bars are among the most dangerous places to socialize due to the form of interaction. Exchange of bacteria and viruses are facilitated intensively from the mouth and nose via air transport in droplets of saliva and bodily fluids being deposited on surfaces, foods, and in the air. The present development creates a comfortable environment where the air-space of each customer is separated by invisible cold-hot air and vis-UV barriers, which take away bacteria and viruses, destroying them and preventing recirculation while offering pleasant, clean, and sanitized ambient conditions for a face to face meeting. An immersive experience can be provided with surrounding screens and gas therapy that may be customized according to the customer's preferences. Food distribution is performed with a robotic shuttle system and when the customer departs, an extensive cleanup is performed using chemicals and UV irradiation through robotic systems.

An internet-of-things (IOT) robotic sterilization system that operates autonomously for use in the prevention of diseases, e.g., Coronavirus Disease 2019 (COVID-19), caused by pathogens such as coronavirus SARS-CoV-2 and other pathogens present within an interior space is described. A robotic sterilization device is communicatively coupled to the IOT base module via an IOT network, and includes a misting or fogging system fluidically coupled to a liquid reservoir, a sensor module including plurality of sensors, a controller, and a locomotion system. The robotic sterilization device navigates a path within the interior space while creating a disinfecting mist with the misting system, and may coordinate with other IOT-connected devices, such as the HVAC system, UV Vent sterilizers, scent dispensing appliances, and others to more efficaciously sanitize the interior space to protect humans by eliminating pathogens.

A robot cleaner for cleaning ambient air in a cleaning area while cleaning a cleaning surface, and a system thereof. The robot cleaner and the system thereof comprise a body, a driving part driving a plurality of wheels disposed at a lower portion of the body, a dust suction part formed in the body to draw-in dust from a cleaning surface, and an air cleaning part formed in the body to draw-in dust-ladened air from a cleaning area. The robot cleaner cleans the air and discharges cleaned air, and, utilizing a controller disposed in the body, controls the driving part and the air cleaning part. Accordingly, since the robot cleaner provides cleaned and fresh air to a predetermined cleaning area while cleaning a surface, it contributes to a fresher residential environment.
