Abstract: An endoscopic surgical instrument may include: two surgical instrument modules, each of which is provided with a surgical instrument portion; and/or an endoscopic module configured to form a triangular shape with the two surgical instrument modules and configured to capture operations of the surgical instrument modules at different angles using a plurality of joints. Wires connecting respective members coupled by the plurality of joints may be configured to amplify drive forces of a drive portion applied to the plurality of joints. The plurality of joints may include rolling joints at which teeth of gears engage and rotate with each other. The plurality of joints may provide three or more degrees of freedom to the endoscopic module.

Abstract: A single port surgical robot capable of setting the location of a remote center motion (RCM) point, and a control method thereof includes: a first link connected to a body by a first joint in a direction perpendicular to the body, the first link having a linear structure; a second link connected to the upper end of the first link by a second joint, the second link having a curved structure; a third link connected to the upper end of the second link by a third joint, the third link having a cylindrical structure; a plurality of light-emitting units arranged on the lower end of the third link along the circumference of the third link, and configured to emit light toward a remote center motion (RCM) point; and a controller configured to adjust the location of the RCM point.

Abstract: Disclosed is an active skin including: a tactile sensor substrate which includes a first film including a dielectric elastic material and formed with a plurality of sensing points, and a pair of first electrodes respectively formed on upper and lower sides of the sensing point; a tactile actuator substrate which includes a second film including a dielectric elastic material and formed with a plurality of actuating points, and a pair of second electrodes respectively formed on upper and lower sides of the actuating point; and an insulating layer which is interposed between the tactile sensor substrate and the tactile actuator substrate and couples the tactile sensor substrate and the tactile actuator substrate. With this, a tactile sensor and a tactile actuator are integrated, so that there is provided an interactive tactile interface to not only feel like a human's skin but also actively move like a muscle.

Abstract: A three-dimensional (3D) radio frequency identification (RFID) tag and an environment condition recognition system and method using the 3D RFID tag are provided. The environment condition recognition system capable of recognizing position and orientation of the object includes a plurality of RF tags each having a self identifier ID, being independently disposed, and having an orientation with respect to a main axial direction, an RFID antenna activating the tags and initiating connection with the RF tags, a reader connected to the antenna and reading information of the RF tags, and an analysis unit connected to the reader and collecting and analyzing the information of the tags.

Abstract: A three-dimensional (3D) radio frequency identification (RFID) tag and an environment condition recognition system and method using the 3D RFID tag are provided. The tag, system and method are capable of recognizing the orientation of a mounted object as well as its intrinsic characteristics and position, thus presenting a new paradigm in the field of autonomous object sensing, identification, and recognition technology. The environment condition recognition system capable of recognizing position and orientation of the object includes a plurality of RF tags each having a self identifier ID, being independently disposed, and having an orientation with respect to a main axial direction, an RFID antenna activating the tags and initiating connection with the RF tags, a reader connected to the antenna and reading information of the RF tags, and an analysis unit connected to the reader and collecting and analyzing the information of the tags.
