1. A disinfection robot capable of autonomous driving and recognition of a disinfection target, comprising:
at least one processor; and
at least one memory storing instructions executable by the at least one processor;
wherein the instructions, when executed by the at least one processor, cause the disinfection robot to:
generate recognition information by recognizing a surrounding environment of the disinfection robot;
move a position of the disinfection robot;
emit a light of a predetermined wavelength area from a light source accommodated in a body of the disinfection robot for disinfection;
inject a fluid for disinfection in a direction opposite to a moving direction of the disinfection robot when the robot moves in one direction;
move the disinfection robot based on the recognition information;
identify a disinfection target from the recognition information and control at least one of the light source and an injecting direction of the fluid to perform disinfection to at least one of the surrounding environment of the disinfection robot and the disinfection target;
provide a guidance speech requesting a recognized person to move away through a speaker of the disinfection robot when the disinfection robot recognizes the person based on the recognition information during the disinfection;
based on the disinfection robot recognizing the person, close the body to prevent the person being exposed to the light of the light source; and
operate the light source and inject the fluid for disinfection selectively or sequentially in consideration of characteristics of the disinfection target, or operate the light source and inject the fluid at a same time in consideration of the characteristics of the disinfection target.
