Disclosed are a robot and a method for delivering articles by the robot. A robot, according to an embodiment of the present disclosure, includes: one or more loading spaces configured to load articles; a travel driver configured to move the robot; an input interface configured to obtain identification information of the articles; a measurer configured to measure temperature of each of the articles; a temperature regulator configured to heat or cool the loading spaces; and a controller configured to determine a type of each of the articles from the identification information, determine a delivery route based on the determined type of article, and control the temperature regulator based on the measured temperature while controlling the travel driver such that the robot moves along the determined delivery route. Examples of the present disclosure are implemented by executing a machine learning algorithm in a 5G environment connected for Internet of things (IoT).
