A robot monitoring method includes: acquiring information related to rotation of wheels of a robot while the robot is traveling along a route in a specific area; calculating, by a calculation circuit, a travel distance of the robot along the route based on the acquired information; calculating, by the calculation circuit, an actual distance corresponding to the route traveled by the robot; and in a case where a difference between the calculated travel distance and the actual distance is greater than a predetermined threshold, generating, by an alert generator, an alert regarding wear of the wheels of the robot.

A robot management system includes: a robot device that imitates a pet; a user terminal device that an owner of the robot device uses; a maintenance terminal device for maintaining the robot device; and a server that communicates with the user terminal device and the maintenance terminal device. The robot device includes a robot storage that stores control data to perform an action individually unique to the robot device, and transmits the control data stored in the robot storage to the user terminal device in response to a request from the user terminal device. The maintenance terminal device receives the control data stored in the server and transmits the received control data to the robot device. The server receives the control data from the user terminal device, stores the received control data, and transmits the stored control data to the maintenance terminal device.
