Disclosed herein is a robot, which has a simple structure and makes a gesture in a curved shape. The robot includes a body part, at least one cam member symmetrically arranged at both sides of the inside of the body part, an outer cover member surrounding the at least one cam member, and a linear moving device to linearly move the at least one cam member. The shape of the outer cover member is varied, under the condition that the outer cover member is adhered closely to the at least one cam member, according to the movement of the at least one cam member.

A dialogue system uses an extended domain in order to have a dialogue with a user using natural language. If a dialogue pattern actually input by the user is different from a dialogue pattern predicted by an expert, an extended domain generated in real time based on user input is used and an extended domain generated in advance is used to have a dialogue with the user.

An intelligent network system including a client unit and a server unit providing a service to the client unit, and a method and computer-readable medium controlling the same are disclosed. If the server unit copies a process that performs a service requested by the client unit into the client unit, and the server unit cannot provide the service any longer, the process is copied to another available server unit so that the service can be continuously provided. Also, if there is no available server unit, the client unit receives the service using the copy process pre-stored in the client unit itself. Therefore, although the network or the peripheral device is in the worst state, the client unit can stably receive the service.

Disclosed herein is a system which transmits an image using a lossless compression method in a robot to provide a service over a network and a method thereof. The network-based robot separates an image acquired by a stereo camera into various image formats and transmits the various image formats to a service server. The service server synthesizes the separated image formats to suit an image request such as face recognition, object recognition, navigation or monitoring to restore and provide an original image. When the network-based robot transmits the separated image formats to the server, the original image is transmitted using the lossless method to improve the performance of the server. Even when a service using a new image is added, separated images are transmitted with respect to the image format requested by this service to more flexibly cope with the service using the new image. Since channels are separated in order to receive lossless data, network gain is obtained.

A movable display apparatus, a robot having the movable display apparatus, and a display method thereof, and, more particularly, a display method of a robot having an apparatus to display an image according to a visual point of a user are provided. It is possible to provide a convenient extended image service, by movably mounting the apparatus to display the image according to the visual point of the user and mounting the movable display apparatus in the robot so as to accurately display the image according to the visual point of the user using the mobility and motion of the robot. In addition, it is possible to provide an image, which is viewed like a three-dimensional image, via a two-dimensional display apparatus, by changing the displayed image according to a variation in the sightline of the user.

Disclosed herein is a robot, which is capable of communicating according to a gesture. The robot includes a plurality of link members, and an outer cover member surrounding the plurality of link members. The shape of the outer cover member is varied into a curved shape, when the outer cover member is adhered closely to the plurality of link members, according to the variation of the shapes of the plurality of link members.

Method and system to detect orientations of a moving object using one or more magnetic compasses. The method and system minimize magnetic field interference in a space where an object is moving such that the orientations of the moving object can be precisely detected. The method includes setting one or more earth magnetic field (EMF) conditions without a magnetic field interference component to determine whether the one or more magnetic compasses are located in an EMF area, calculating a magnitude of a magnetic field applied to the moving object using the one or more magnetic field compasses, and detecting an orientation of the moving object by determining whether the calculated magnitude of the magnetic field satisfies the one or more EMF conditions.

Provided are an apparatus and method of calibrating azimuth of a mobile device. The apparatus includes: a magnetic field measuring unit having a plurality of magnetic sensors aligned in a constant angle interval on the mobile device and measuring magnetic field data indicating magnitudes of a magnetic field in different directions; and a controller generating a calibration table indicating a correspondence between an actual magnetic field trajectory formed by the magnetic field data and a theoretical magnetic field trajectory and calibrating azimuth of the mobile device using the calibration table.
