A robot device according to various embodiments comprises a camera, a robot arm, and a control device electrically connected to the camera and the robot arm, wherein the control device can be configured to collect a robot arm control record about a random operation, acquire, from the camera, a camera image in which a working space of the robot arm is photographed, implement an augmented reality model by rendering a virtual object corresponding to an object related to objective work in the camera image, and update a control policy for the objective work by performing image-based policy learning on the basis of the augmented reality model and the control record.

Robot control apparatus and method for learning task skill of the robot

A hand-eye calibration system and method are provided. The system includes a robot on which a small pattern is mounted, a camera configured to photograph the robot, a memory, and a processor configured to move the robot, acquire posture information of the moved robot, acquire an image from the camera, move the camera after performing the robot movement, the posture information acquisition, and the image acquisition a first predetermined number of times, and perform hand-eye calibration for the robot based on the posture information and the images, which are obtained by repeatedly performing of the robot movement, the posture information acquisition, the image acquisition, and the camera movement.

Hand-eye calibration method and system

Provided is an organic light emitting display device including at least two organic light emitting elements disposed adjacent to each other, respectively including an anode, an organic light emitting unit, and a cathode, and sharing at least one common layer in the organic light emitting unit. The at least one common layer includes a characteristic degradation area that reduces or minimizes an amount of leakage current generated between the at least two organic light emitting elements.

Organic light emitting display device reducing leakage current generated between pixels

Provided is a display device, including two light-emitting elements having different turn-on voltages. Each of the light-emitting elements includes a patterned electrode, a common layer, a patterned light-emitting layer, and a common electrode. The light-emitting element with the lower turn-on voltage among the two light-emitting elements includes a functional layer which suppresses a hole from being leaked from the light-emitting layer with the higher turn-on voltage through the common layer when the light-emitting element with the higher turn-on voltage among the two light-emitting elements is driven at a low gray scale to move into the patterned light-emitting layer of the light-emitting element with the lower turn-on voltage. Therefore, the light emission of an undesired pixel due to the leakage current is reduced, thereby improving the display quality.
