Disinfection robot, system for disinfection, and method of disinfection

Disinfection robot for disinfecting a, preferably indoor, space such as a room of a hospital or a nursing centre, by means of ultraviolet radiation, wherein the disinfection robot is arranged to include, and preferably includes, a radiation source that is arranged for emitting the ultraviolet radiation, wherein the disinfection robot also includes movement means for moving the radiation source in the space and sensor means for generating a sensor signal that is indicative for a position of the radiation source in the space, wherein the robot further includes a controller that is arranged for receiving the sensor signal, preferably is communicatively connected to the sensor means for receiving the sensor signal, and that is arranged for controlling the movement means for moving the radiation source along a path in the space, said path being formed by a sequence of the positions of the radiation source in the space, wherein the controller is further arranged for determining a cumulative exposure pattern of the emitted ultraviolet radiation in the space based on the path, on a duration and/or velocity of movement of the radiation source along the path, and on an intensity and/or direction of the ultraviolet radiation emitted during movement along the path, wherein the controller is arranged for determining a target position to extend the path in the space based on the sensor signal and on the cumulative exposure pattern in the space, and for controlling the movement means for moving the radiation source towards the target position.
