A robot rotates frontward, rearward, clockwise, or counterclockwise such that a display device is matched with the eye position of a user. The robot includes a body, a display device, and at least one bending device. The display device includes a recognition unit to rotate about the body according to the position of the user. The recognition unit detects a position of a user. The bending device couples the body with the display device such that the body and the display device rotate frontward, rearward, clockwise, or counterclockwise according to a detection state of the recognition unit.

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.

A system to provide various content services based on a network to users includes a service provider to provide a service using the network, a user to receive the service, and a service framework to provide the service to the user through the network. The service framework includes a messenger device that manages the service transmitted between the service provider and the user. Content services, which are being provided based on a network, can be provided to various terminals including not only a PC and a mobile phone, but also a robot. Thus, extending services is easy and the user can conveniently receive desired information from a knowledge provider or website without performing repetitive operations.

摘要:
The present invention relates to a power factor correction circuit and a driving method thereof.The power factor correction circuit includes a power switch controlling an inductor current flowing in an inductor, an auxiliary inductor coupled to the inductor with a predetermined turn ratio, and a power factor correction controller controlling output power by controlling a switching operation of the power switch.The power factor correction controller determines whether or not an output voltage of the output power is an over-voltage by using the sum of a source current and a sink current that control a zero current detection voltage to be included within a predetermined clamping range, the zero current detection voltage corresponding to an auxiliary voltage that is a both-end voltage of an auxiliary inductor.
