Abstract:
A three dimensional (3D)imaging system capable of effectively displaying a 3D image suitable for a user by use of different cameras, and an image reproducing method thereof, the 3D imaging system configured to have different cameras freely selected without restriction while enabling the placement of the cameras thereof to be changeable according to the disposition of eyes of the user, so that a 3D image is generated and displayed from a stereo image adapted to the user, and by using the by-user generated 3D image, various contents services including a real time broadcasting, a Contents on Demand (COD), games, and a video communication are provided to a user, so that the fatigue or dizziness of a user is reduced, and the optimum perception of 3D sense is provided.
Abstract:
A wearable robot may be worn by a user to record or teach a motion, including a motion such as sign language. The wearable robot includes a mode to record sign language data in a system by a sign language expert wearing the wearable robot and a mode to teach the sign language data recorded in the system to a sign language learner wearing the wearable robot. A user who wishes to learn sign language may easily learn sign language. In particular, a disabled person, who has poor eyesight and is unable to watch a video that teaches sign language, may learn sign language very intuitively using the wearable robot. Further, a user who has normal eyesight may also learn sign language more easily than from using a video which teaches sign language or from a sign language expert.
Abstract:
A speech signal transmission apparatus includes an extractor to extract speech signals from speech source signals collected by a plurality of microphones, a power calculator to calculate powers of speech signals of multiple channels and set any one of the speech signals of the multiple channels as a reference speech signal, a synchronization adjustor to adjust synchronization of the other speech signals based on the reference speech signal, a signal generator to generate extraction signals by offsetting the reference speech signal from the other synchronization-adjusted speech signals, an encryptor to compress and encrypt the reference speech signal and the extraction signals, and a transmitter to transmit the compressed and encrypted reference speech signal and extraction signals.
Abstract:
Disclosed herein are a walking assistance apparatus including a drive portion capable of adjusting tension of a fixing portion, and a method of controlling the same. The walking assistance apparatus includes a support portion which applies assist power to assist walking to a human body, a fixing portion which is arranged at one end of the support portion to enclose the human body and fixes the support portion on the human body, a drive portion including at least one motor which adjusts tension of the fixing portion, and a control portion which adjusts a driving direction of the at least one motor during rotation of the support portion in order to prevent the fixing portion from rotating by assist power applied through the support portion.
Abstract:
A walk-assistive apparatus may include at least one joint that corresponds to at least one joint of a wearer, at least one link that connects the joint, and is rotated in response to rotation of the joint, a spring that is mounted in the link or the joint so that a length of the spring is changed in accordance with rotation of the link or the joint, and a processor that controls the change in the length of the spring to compensate for a weight by gravity when the wearer walks. Accordingly, the walk-assistive apparatus and a method of controlling the walk-assistive apparatus may use a mechanical element such as a spring to reduce energy, and weight compensation having uniform performance may be performed even in an arbitrary posture.
Abstract:
Disclosed herein is a control method of a robot including: calculating hardness information about the ground on which a wearer moves; and controlling the robot according to the calculated hardness information.
Abstract:
A surgical robot system includes a slave device provided with a surgical instrument and a master device to control motion of the surgical instrument. The master device includes a master manipulation module having a manipulation tool, to which a pose recognizer is attached, and a master control module that estimates a pose of the manipulation tool using pose information acquired via the pose recognizer, generates a surgical instrument pose control signal corresponding to the estimated pose of the manipulation tool, and transmits the control signal to the slave device.

Abstract:
Disclosed herein are a cleaning robot and a method of controlling the same. The cleaning robot according to one embodiment includes a modular in which one or more modules configured to support different functions are integrated, and a controller configured to control the overall operation of the cleaning robot.
Abstract:
A muscular strength assisting apparatus may include: a wearing unit configured to enclose a part of a user's body; a tightening unit configured to pull the wearing unit in one or both directions; and/or a control unit configured to drive the tightening unit to tighten the part of the user's body on which the wearing unit is located, when it is determined that muscular contraction occurs at the part of the user's body on which the wearing unit is located. A method of controlling a muscular strength assisting apparatus may include: determining whether muscular contraction occurs at a part of a user's body that is enclosed by a wearing unit; and/or driving a tightening unit pulling the wearing unit in one direction or both directions to tighten the part of the user's body on which the wearing unit is located when it is determined that the muscular contraction occurs.
