1. A robot-executed method of disinfection of a site by an autonomous movable robot equipped with at least one germicidal UVC light source, the method comprising:
using an exploration strategy to move within the site to generate a map and disinfection costmap of the site in 2D or 3D, while performing disinfection of surfaces;
generating a trajectory based on the disinfection costmap, wherein the trajectory considers a need to explore and map the site, power consumption and shadow areas; and
while performing disinfection, generating a global dosage delivery map in 2D or 3D based on the executed trajectory and consequent shadow areas.
