A robot apparatus for detecting a sound signal outputted from a sound signal generating means to move to a position of the sound signal generating means, wherein the sound signal has a specific pattern, the robot apparatus comprising:
- at least three sound receiving means for receiving the sound signal outputted from the sound signal generating means;
- a phase difference detection means for detecting a phase difference between each sound signals from the sound receiving means;
- a processing means for determining a position of the sound generating means using the phase difference, to generate a moving control signal;
- and
- a moving means, in response to the moving control signal, for moving the robot apparatus to the position of the sound generating means.
A method for operating a robot apparatus for detecting a sound signal outputted from a sound signal generating means to move to a position of the sound signal generating mean, wherein the sound signal has a specific pattern, the method comprising the steps of:
- a) determining whether an operation mode is set up;
- b) if the operation mode is not set up, setting up a standby mode to sense and trace a human body being within a predetermined distance;
- c) if the operation mode is set up, determining kinds of operation mode;
- and
- d) according to the operation mode, clearing a predetermined area by using an information of a plane structure obtained by searching and analyzing the plane structure, docking to a charger by searching the charger generating a sound signal when a battery of the robot is discharged, searching a sound source for generating a sound signal and performing a guard operation.
