Abstract: A method for controlling a mobile robotic apparatus for disinfecting a space includes acquiring, by a data processing unit of the mobile robotic apparatus, a map of the space to be disinfected, acquiring information on a plurality of contact surfaces to be disinfected within the space to be disinfected, each contact surface being associated with a criticality level, determining an amount of ultraviolet-C, UV-C, radiation energy to be deposited, by a UV-C radiation source, on a contact surface, the amount of UV-C radiation energy being determined as a function of the criticality level, distance and orientation of the contact surface with respect to the UV-C radiation source and of set operating features of the UV-C radiation source, determining a respective virtual potential of attraction of the UV-C radiation source towards each contact surface, generating a path trajectory, and controlling the mobile robotic apparatus along the generated path trajectory.
