Abstract : Disinfecting a closed space is a widely discussed topic since the spread of coronavirus. Different methods like chemicals in liquids and gases are used to eliminate pathogens. But these methods would cause environmental damage, which would become another problem for humanity. We developed a robot which uses ultraviolet-C (UV-C) technology for surface disinfection, particularly room in houses, offices, hospitals etc. UV-C radiation is effective against coronavirus and is extremely effective in breaking down the DNA of microorganisms which means they cannot replicate and cause disease. The teleoperated robot is capable of 360-degree disinfection with three UV-C lamps used. It is controlled using an Android app through Bluetooth wireless interface. Due to wireless control, the operator can safely operate the robot from outside the room. The robot is also equipped with a self-timer for turning off the UV-C lamps automatically. The robot has been deployed in our lab and Amrita Institute of Medical Sciences, Kochi to sanitize the patient's rooms and bathrooms.
