Abstract: A method of controlling a moving robot includes a travel control operation in which the moving robot generates field data by sensing information regarding an environment around the moving robot, and controls autonomous traveling based on a recognition result that is obtained by inputting the field data to a recognition algorithm for the moving robot; a server learning operation in which the moving robot transmits at least some of the field data to a server or other device and the server generates update information based on the field data transmitted by the moving robot; and an update operation in which the server transmits the update information to the moving robot, which uses the update information to update the recognition algorithm.
