Abstract:
According to an embodiment of the present invention, a torque limiter capable of changing a yielding torque according to a driving angle includes: a first slide unit having a spring, a pusher disposed at a front end of the spring, a rotor bearing coupled to a frond of the pusher; a rotor cam having a section surface, generating a yielding force by a contact shape with the rotor bearing, fixing a location of the rotor bearing without a rotational displacement below a predetermined torque applied from outside, and generating an instant rotational displacement when the predetermined torque is exceeded; a second slide unit installed facing the first slide unit, and having a pusher, and stator bearing coupled to a front end of the pusher; a stator cam contacting the stator bearing and fixed to not rotate; a lever unit connected between the first slide unit and the second slide unit changing the yielding torque by compressing or extending the spring of the first slide unit through a movement of the second slide unit; and a rotor relatively rotating between the rotor cam and the stator cam.
Abstract:
PURPOSE: A human-robot collaboration system and a part assembling method based on the same are provided to prevent accidents in task by informing excessive contact force to an operator through a monitoring device and controlling the contact force by a robot controller. CONSTITUTION: A part assembling method based on a human-robot collaboration system(100) is as follows. Information with respect to a location and the movement of a robot(20) is saved while assembling parts by operating the robot according to a direct order of an operator. Parts are automatically assembled based on the saved information. The information with respect to the location and the movement of the robot is corrected according to an additional order of the operator when assembling errors are generated.

Abstract:
An image signal processing method having a wide dynamic range by a physical property of an image sensor is provided to combine a fast shutter and a slow shutter with one image pickup device to generate two image signals of different exposure times and combine images by using a response property according to luminance of an image sensor, thereby preventing brightness of the entire image from being drastically changed despite a peak value change of the image. A response function is calculated by converting a plurality of images photographed at various exposure times with regard to the same subject into gray level images(S100). An exposure time difference between a long time exposure image and a short time exposure image is set(S200). Two image photographed with regard to the same subject by the exposure time difference are color-converted into a CIE-XYZ space(S300). The two images are converted into a CIE-Yxy again(S400).
Abstract:
A compact cable transmission system is provided to reduce noise in comparison with a differential device by forming a cable path at a bevel pulley. A first bevel pulley(100) includes a cable path groove(110) having a depth larger than a radius of a cable. The cable is inserted in a circumferential direction around a rotary shaft of a cone-shaped bevel gear. A horizontal rotary shaft module(300) is coupled with the first bevel pulley. A vertical rotary shaft module(400) is coupled perpendicularly to the horizontal rotary shaft module. A second bevel pulley(200) is coupled with the vertical rotary shaft module in order to be maintained in a constant interval from the first bevel pulley. The second bevel pulley includes a cable path groove(210) corresponding to the cable path groove of the first bevel pulley. Both ends of the cable are coupled with the cable path grooves of the first and second bevel pulleys. The cable is wound around the cable path grooves of the first and second bevel pulleys in order to transmit the power.
