A robot includes; a driving module, a communication module, and at least one processor configured to receive, a second docking guidance signal output from a second docking station; determine a first output time of the received second docking guidance signal, determine a second output time of a first docking guidance request signal to be transmitted based on the determined first output time to prevent the first docking guidance request signal from overlapping with the second docking guidance signal, and output the first docking guidance request signal, through the communication module, based on the determined second output time of the first docking guidance request signal, and in response to the outputting of the first docking guidance request signal, receive, a first docking guidance signal, docking the robot to the first docking station by driving the driving module in response to receiving the first docking guidance signal.
