A control method of a single-port surgical robot, the single-port surgical robot comprising a slave device including a surgical instrument provided with an elbow and an end effector, and a master device to control motion of the slave device may comprise setting a virtual incision port to an arbitrary position; setting an operating position of the end effector; calculating a target position of the elbow using the set position of the virtual incision port and the set operating position of the end effector; calculating a movement angle of each joint used to move the elbow using the calculated target position of the elbow; and/or calculating a movement angle of each joint used to move the end effector using the calculated target position of the elbow and the set operating position of the end effector.

A dialogue system and a method for the same are disclosed. The dialogue system includes a multimodal input unit receiving speech and non-speech information of a user, a domain reasoner, which stores a plurality of pre-stored situations, each of which is formed by a combination one or more speech and non-speech information, calculating each adaptability of the pre-stored situations on the basis of a generated situation based on the speech and the non-speech information received from the multimodal input unit, and determining a current domain according to the calculated adaptability, a dialogue manager to select a response corresponding to the current domain, and a multimodal output unit to output the response. The dialogue system performs domain reasoning using a situation including information combinations reflected in the domain reasoning process, current information, and a speech recognition result, and reduces the size of a dialogue search space while increasing domain reasoning accuracy.

Dialogue system and method for responding to multimodal input using calculated situation adaptability

A robot and method to recognize and handle abnormal situations includes a sensing unit to sense internal and external information of the robot, a storage unit to store the information sensed by the sensing unit, an inference model, a learning model, services providable by the robot, subtasks to provide the services, and handling tasks to handle abnormal situations, and a controller to determine whether an abnormal situation has occurred while the subtasks to provide the selected service are being performed through the learning model in the storage unit and to select a handling task to handle the abnormal situation through the inference model in the storage unit if it is determined that the abnormal situation has occurred. The robot may recognize and handle abnormal situations even though data other than that defined by a designer of the robot is input thereto due to noises or operational environment.

Robot and method to recognize and handle abnormal situations

A robot, which may accurately detect whether or not the robot is gripping an object, even without a tactile sensor, as a result of using a sorter that utilizes a torque generated from a joint of a hand and the shape of the hand as feature data, and a control method for the robot includes a state sensing unit to sense a state of the robot, a feature vector producing unit to extract feature data from the state sensing unit and to produce a feature vector using the feature data, and a learning-based data sorter to judge an operating state of the robot using the feature vector produced by the feature vector producing unit and to output the judged result.

Robot and control method for the same

An interactive robot may audibly communicate with a user, determine whether reasoning is performed according to a reasoning weight of a schedule if there is a schedule to be recommended by the interactive robot during conversation between the interactive robot and the user, perform reasoning using information collected in a database if reasoning is necessary, and provide schedule information to the user.

Schedule management system using interactive robot and method and computer-readable medium thereof

A multilingual dialogue system enabling a user to conduct dialogue in various languages, and a controlling method thereof. According to the multilingual dialogue system and the controlling method, reliability of the user's language can be evaluated, thereby coping with errors generated during dialogue.
