COMMUNICATION SYSTEM, AUTONOMOUS NAVIGATION ROBOT HAVING REPEATER AND COMMUNICATION METHOD THEREOF

摘要

PURPOSE: A communication system including a repeater, an autonomous robot, and a communication method thereof are provided to enable a robot to maintain smooth communication with a remote control terminal. CONSTITUTION: A mounting unit(110) includes multiple dent areas formed on the boundary of a main body. One or more repeaters(200) are mounted on the mounting unit. An electromagnet unit(120) attaches or detaches a repeater with an electromagnetic force. When communication sensitivity with a remote control device is reduced, a control unit applies the electromagnetic force to the electromagnet unit. The control unit drops the repeater mounted on the mounting unit to the ground. The control unit communicates with the remote control device through the corresponding repeater.
