Abstract:
PURPOSE: A rotary compliant joint using a spring and a damper adopting magneto rheological fluid is provided to have a manual compliant function against external force by using the spring, to reduce shock applied in colliding peripheral objects or persons with machines having joints or robots, and to prevent accidents and breakages of the joint by minimizing impulse applied to the objects and the joint to the reduction of shock. CONSTITUTION: A rotary compliant joint(100) for mutually connecting first and second links to relatively rotate is composed of a housing(111) connected with a driving unit to rotate and rotatively fixed for the first link; a rotor(161) of which one end is rotatively inserted into the housing and the other end is connected to the second link; magneto rheological fluid(115) filled between the inside of the housing and the rotor to change yield stress to magnetic flux density; a plurality of springs(169) inserted into a circular groove(112) formed at the side of the housing facing the second link; and a cover(163) fixed to the other end of the rotor to close the groove and to expand and contract the springs with interlocking to the second link.

PURPOSE: A device for controlling the position of an object with rotary two-degrees of freedom is provided to reduce manufacturing costs by using a single servo-motor and controlling the position of the object. CONSTITUTION: A device for controlling the position of an object with rotary two-degrees of freedom is composed of a hollow housing(10), a single servo-motor(12) installed in the housing, an object receiving the driving force from the servo-motor and moving to predetermined position, a first gear train connecting the servo-motor with the object and rotating the object by the driving force of the servo-motor, and a second gear train. The second gear train connects the servo-motor with the object, and turns the rotation axis of the object by the driving force of the servo-motor.

PURPOSE: A flexible gripper for feeding workpieces having a plurality of gripping points is provided to automatically adjust the position of the gripper according to the size and shape of the workpieces by the predetermined program. CONSTITUTION: A machine performs same repetitive operations and works with a various workpieces. A flexible gripper for feeding workpieces needs the separate attachment operations for gripping the respective workpieces. The gripping device(26) changes gripping points with respect to the size and shape of the workpieces with the position attaching a respective gripper of the gripping device being movable to the predetermined position set by the program at three dimensional space.

PURPOSE: A multi-branched robot hand is provided to enable a bending movement using a four links structure composed of joints to perform the robot hand operation similar with a real hand movement. CONSTITUTION: A multi-branched robot hand is composed of a first finger(A,B,C) composed of a first joint(A1,B1,C1) and more than two sections, a first module box(206,209), and hand base(213) attached to the first module box. The first joint(A1,B1,C1) engages one side of the upper section(201,204,207) with one side of the lower section(202,205,208). The fist module box(206,209) includes a second joint(A2,B2,C2) to engage one side of the upper portion with the other side of the lower section of the first finger to support the first finger. The multi-branched robot hand further comprises an auxiliary link for engaging one side of the upper section of the first finger with one side of the upper portion of the first module box. The auxiliary link forms a four-joints link structure with the upper section of the first joint, the lower section of the second joint, the auxiliary link, and the first module box.
