  • Publication number: 20060232086
    Abstract: A robot hand includes a drive unit having a pair of moving elements provided so as to be movable in a lateral direction with respect to a center axis extending parallel with a longitudinal direction of an arm part to which the robot hand is attached, a pair of gripping claws each coupled to one of the pair of moving elements of the drive unit, and a joint for coupling the pair of gripping claws to each other so as to be pivotable. Each of the pair of gripping claws has a base end coupled to one of the moving elements so as to be pivotable and a front end for engaging with a workpiece. The pair of moving elements are operated to approach and move apart from each other in a lateral direction with respect to the center axis, thereby making the pair of gripping claws pivot about the joint and making the front ends of the gripping claws move apart from or approach each other.

  • Publication number: 20040266276
    Abstract: An intermediate portion of a cable with connector is pinched by a pair of rolls of a first hand of a first robot, and the connector provided to the cable is fixed by causing the firsthand to approach. An image of this connector is obtained by a first camera and a position and posture of the connector are found. A second robot is moved to a gripping position which has been corrected based on the position and posture of that connector, thereby causing the second hand of the second robot to grip the connector at an outer periphery thereof.

  • Patent number: 5133047
    Abstract: A robot control method of the playback type and an apparatus for using the method in which position data and data regarding velocity are taught at a sequence of points for a work program, and a servo system is driven by the use of the taught data to playback or repeat the work program. Phase angles which increase as the robot progresses through the sequence of teaching points are taught as the data regarding the velocity of the work program. At playback, a reference phase angle computed on the basis of a previously-set playback cycle time for the work program. The reference phase angle increases at an advance velocity which decreases with an increase in the playback cycle time. During operation, the reference phase angle is compared with one of the taught phase angles, and the corresponding taught position data is outputted to the servo system when the reference phase angle exceeds the taught phase angle.

  • Patent number: 5086262
    Abstract: An industrial robot system comprising a plurality of robots for conducting a work in cooperation with each other. A system clock is provided in the system, and clocks are provided in the respective robots. These clocks are counted up at the same cycle time, and are set for original points of the respective robots, which are the waiting positions thereof, and the clock values of the robots located in the respective positions during the drive operation. During the drive of the system, the system clock is advanced by adding a predetermined increment value thereto, and the respective robots held under the enabling condition, start the operations by advancing the robot clocks by adding the same increment value as that of the system clock.

  • Patent number: 4683544
    Abstract: An off-line teaching method for an industrial robot wherein a master robot, separate from a line robot, placed in an actual operation line, and a model work similar to the line work processed in the operation line are prepared. Four predetermined points which are not in the same plane are obtained on each of the works, and are taught to the line and master robots in the same order to obtain a reciprocal transformation matrix. The transformation matrix is used to automatically transform an operation program taught to the master robot into an operation program for the line robot.
