  • Patent number: 8424942
    Abstract: An industrial gripper includes a base plate, at least three finger units to be moved relative to the base plate, a supporting unit to support the finger units, a first drive unit coupled to the supporting unit to allow simultaneous angular displacement of the finger units toward an object, and a second drive unit coupled to the supporting unit to adjust orientation angles between the finger units. Each of the finger units includes an intermediation member to be moved in a first direction by the first drive unit, a grip member to grip the object by being moved in a second direction different from the first direction as a movement direction of the intermediation member, and a connection member to convert the first direction movement of the intermediation member into the second direction movement of the grip member.

  • Patent number: 7751939
    Abstract: An apparatus and method of optimally correcting a static deflection caused by a weight of an end effector coupled to a robot arm or a load on the end effector when the end effector is activated to handle a large sheet of glass. A deflection angle of the end effector is corrected by inserting a compensation member into a joint of the robot arm, and the static deflection caused by the weight of the handling robot when conveying the sheet of glass is also corrected in real time.

  • Patent number: 6135683
    Abstract: A six-degree-of-freedom parallel mechanism is provided for expanding a grade of a spindle. The parallel mechanism has a spindle that turns round a workpiece at a tilting angle of 90.degree. in a workspace, to thereby allow a machining for both vertical and horizontal planes of the workpiece, and a vertical turning process, by a single machining center. A six-axis multi-machining type machining center embodying the parallel mechanism of the present invention is also disclosed. An over-actuated multi-machining type machining center further including over-actuated actuators is presented to solve a problem of driving joints' singularity caused by the parallel mechanism.
