Abstract: Disclosed herein is a wave generator for a reducer of a harmonic drive structure. The reducer of a harmonic drive structure includes: a circular spline of a ring shape; a flex spline mounted inside the circular spline and having teeth engaged with teeth formed at three or more positions of the inner circumferential surface of the circular spline to be rotated; and a wave generator mounted inside the flex spline, and including a cam plate of a circular shape, and three or more protrusions formed at three or more positions of the outer circumferential surface of the circular cam plate so that the protrusions formed on the outer circumferential surface of the cam plate elastically deform the three or more positions inside the flex spline.

Abstract: Provided are an apparatus and method for supplying a light-emitting diode (LED) wafer that may quickly and accurately transfer LED wafers by acquiring position information of pockets in a carrier in which the LED wafers are to be seated. The apparatus may include a cassette in which a plurality of LED wafers are loaded, a carrier including a plurality of pockets in which the LED wafers are seated, an aligning unit to align the LED wafers that are to be seated in the carrier, a transfer robot to transfer the LED wafers from the cassette to the aligning unit, a picker to hold, in an adsorbed state, the LED wafers transferred to the aligning unit, or to release the adsorbed state, a capturing unit to fix the picker, and to acquire position information of the pockets, and an LED wafer loading robot to transfer the picker and the capturing unit from the aligning unit to the carrier.

Abstract: A light-emitting diode (LED) wafer picker that may increase a suction force and may perform stable adsorption without a concern for contact with a top surface of an LED wafer is provided. An LED wafer picker may include a main body to hold, in an adsorbed state, an LED wafer disposed below the main body, when air drawn in from a top of the LED wafer picker is discharged along a streamlined discharge surface to both sides of the LED wafer picker, a guide member to enable the air to flow along the discharge surface, the guide member being disposed below the discharge surface, a single central hole formed in a central portion of the guide member, excluding a portion facing the discharge surface, and a support portion to support the LED wafer, the support portion extending downward from the guide member. Accordingly, it is possible to easily perform adsorption of an LED wafer that is relatively far from the LED wafer picker.

Abstract: The present disclosure provides a multi-channel video distribution method and apparatus, and a video management system using the same, including a client system to communicate with a standardized video providing apparatus or a non-standardized video providing apparatus, and to receive a video/sound signal from the standardized video providing apparatus or the non-standardized video providing apparatus; a transcode system to convert the video/sound signal, received by the client system, to a video/sound format that is requested in a client application; and a server system to communicate with the client application, and to transmit, to the client application, the video/sound signal that is converted by the transcode system.

Abstract: The present invention relates to a PC-based robot control system, which is a new type of a robot control machine. The present invention has aimed at a task-based control machine configuration not a centralized control configuration so that a multi-tasking function is possible through a distributed control system.
