Abstract:
PURPOSE: A device using polarized lights for measuring a 3D shape and thickness is provided to simultaneously obtain a surface shape and the thickness information of a target object by using the polarized lights. CONSTITUTION: A device(200) using polarized lights for measuring a 3D shape and thickness comprises a white light source(210), a first beam splitter(220), a linear polarizer(230), a second beam splitter(270), a mirror(280), and a spectroscope(290). The first beam splitter sorts white light incident from the white light source into reference lights and measurement lights, thereby irradiating the same respectively to a reference mirror(240) and a measurement object(260). The first beam splitter interferes in the reference and measurement lights, which are reflected by the reference mirror and measurement object, thereby generating coherent lights. The linear polarizer linear-polarizes the reference lights so that the reference lights have only first polarizing components.

PURPOSE: A master arm structure of a robot for an operation and a method for controlling a master robot are provided to control the operation of a master arm by operating a break installed on each joint after detecting an operation state of the master arm so that a user feels haptic feedback when manipulating the master arm. CONSTITUTION: A master arm structure of a robot for an operation comprises a handle(3), an arm part(10), a brake(16), a detecting part(20), and a control unit(30). The handle is operated by a user. The arm unit connects a master robot and the handle and is formed into a structure that a plurality of arm members(12) is connected by a joint(14). The arm members rotate around the joint so that the handle is positioned. The brake is installed in the joint and controls the rotation of the arm members The sensing unit obtains information with respect to one or more of a state that the handle is operated and a state that the arm part is operated. The control unit controls the operation of the brake by using the information obtained by the sensing unit.

PURPOSE: A moving structure of a 1-DOF(Degree Of Freedom) gripper system, the detachable 1-DOF gripper system, and a driving method thereof are provided to apply a driving system using a wire to the 1-DOF gripper system, thereby obtaining high resolving power. CONSTITUTION: A moving structure of a 1-DOF gripper system comprises an actuator(5), a rotating member(11), and a gripper(12). The actuator comprises a rotary shaft(7). The rotating member receives power from the actuator by using a wire and rotates. The gripper is attached or detached to/from the rotating member. A guide groove is formed on a lateral side of the rotating member in a circumferential direction and the wire is placed in the guide groove. The wire is wound around the rotary shaft. Both ends of the wire are respectively fixed to both sides of the rotating member. A rotational direction of the rotating member is varied according to the rotational direction of the rotary shaft.
Abstract:
PURPOSE: A control method for a surgical robot system capable of determining and managing a surgical situation, a recording medium thereof, and the surgical robot system are provided to automatically perform a predetermined operation for managing a surgical situation by determining a current surgical situation from laparoscope images in real time. CONSTITUTION: Image information including one or more of RGB values or HSV values, which represent pixel information of laparoscope images, is generated from the laparoscope images(S10). An interest region in the laparoscope images is extracted from the generated image information(S20). A current operation situation is determined from changes according to time flow in the extracted interest region(S30). A predetermined operation for dealing with the determined operational situation is performed(S40).

PURPOSE: A griper using a driving wire is provided to directly measure the opening degree of the gripper. CONSTITUTION: A griper using a driving wire comprises first and second actuating units, first and second capstans, first and second rotary shafts, and a driving wire(40). The first and second capstans connected to the first and second actuating units control the first and second actuating units. The first and second rotary shafts are placed at each center of the first and second capstans, and rotate the first and second capstans. The driving wire is wrapped around the first capstan, and wrapped around the second capstan in the opposite direction. The driving wire controls the rotation of the first and second capstans by tensile force.

PURPOSE: A joint device for an active ball socket is provided to obtain the high degree of freedom, and to effectively deliver power with independently controlling each axis. CONSTITUTION: A joint device for an active ball socket comprises a ball(110), a N-th link, a (N+1)th link, a pair of first driving wires(131), a pair of second driving wires(132). The first driving wires are fixed to the (N+1)th link by penetrating the N-th link along a second guide slot. The first driving wires drive the (N+1)th link against a first axis. The second driving wires are fixed to the (N+1)th link by penetrating the N-th link along a first guide slot. The second driving wires drive the (N+1)th link against a second axis.

PURPOSE: A surgical robot system and a control method thereof are provided to prevent structure change by additionally adding an exclusive driving part which is in charge of operational freedom of an instrument. CONSTITUTION: A first driving part(20) combines a robot with an instrument. The first driving part includes the n(N is natural number) number of basic drivers so that the instrument operates at an n freedom degree. A second driver part(30) is combined with the instrument and includes the m number of extra drivers so that the instrument operates at an n+m(n+m is natural number) freedom degree. A sensing part(40) sense drive information of the second driver part and outputs a sensing signal.
