1. A robot comprising:
a container comprising at least one loading space;
a load sensor configured to detect a load weight of the container;
a camera configured to capture images of articles;
a memory configured to store weight information of the articles loaded in the loading space; and
a processor,
wherein the processor is configured to:
determine the weight information based on the load weight;
determine loading characteristics of the articles based on the captured images of the articles;
determine a loading space among a plurality of loading spaces for loading the articles based on the loading characteristics to stably transport the articles;
open the determined loading space; and
determine a route along which the robot is to visit a plurality of destinations based on the weight information, including:
determining whether horizontal moving distances to the plurality of destinations are the same;
in response to the horizontal moving distances to the plurality of destinations being the same, determining a next destination based on weights of the articles to be delivered to each of the plurality of destinations;
in response to the horizontal moving distances to the plurality of destinations being different and the weights of the articles to be delivered to each of the plurality of destinations being the same, determining the next destination based on the horizontal moving distances to the plurality of destinations; and
in response to the horizontal moving distances to the plurality of destinations being different and the weights of the articles to be delivered to each of the plurality of destinations being different, determining the next destination based on the horizontal moving distances to the plurality of destinations and the weights of the articles.
