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.

Abstract: Disclosed are a fixing device and a refrigerator having the same. The fixing device includes a clasp (400) installed to a first member (12), the clasp having a contact portion (402, 404) defining a plane, and a coupler (500) installed to a second member (100), the coupler serving to fix the second member to the first member to enable selective coupling or release of the second member and the first member. The coupler includes a hook (510) having a protruding tip portion (511) configured to come into contact with the contact portions (402, 404) so as to be caught by the contact portion (404), the hook being rotatable, and an elastic member (52,0) configured to elastically support the hook such that the hook is rotated toward the clasp. A contact position of the protruding tip portion and the contact portion is spaced apart from a rotation center of the hook by a predetermined distance (d).
