Abstract
This paper presents the design and map-based teleoperation of a robot with ultraviolet-C (UVC) lamps that disinfects the COVID-19 virus in complex indoor environments. To disinfect a wide range of surfaces, the robot has an arm with six degrees-of-freedom in addition to a wheeled platform. The wheeled platform attaches tube lamps on each side and underneath in the orientation perpendicular to the moving direction, and the robot arm has a spot UVC lamp at its end-effector. A method for projecting surface dosage using light properties is proposed and validated using the sensor measurements from the robotic system. A technique for creating a disinfection map is presented to prove surface disinfection of the environment in three-dimensional space. The developed robot was tested in an indoor environment with typical structures. Experimental results demonstrate accurate disinfection map creation.
