    摘要: It is an object of the invention to provide an articulated robot capable of reducing a number of axes, making the robot light-weighted, reducing fabrication cost and promoting a working efficiency by mounting two or more of hands at a single unit of the robot and sharing portions of axes and its control apparatus. For that purpose, an articulated robot having a plurality of hands at a single unit thereof capable of sharing portions of axes (first axis, second axis) and attaching the hands respectively to tips of a plurality of axes (4A axis, 4B axis) connected to the axes (first axis, second axis) independently therefrom is provided with a control apparatus for subjecting a designated one of the hands to a CP control and switching the hand which is not designated to a PTP control.

    摘要: In the preparatory stage, among all possible lines in two rectangular windows (12) and (14), assuming dust, a flaw or the like to be a part of a line, the most valid one is recognized as a line, and the inclination and characteristic values of the line are obtained, and then each rectangular window is deformed into a parallelogram-shaped window along this inclination. In the detecting stage, the inclination and characteristic values of the line to be detected are obtained by use of the parallelogram-shaped windows. Thus, even if image data is inferior, the detection of a line is possible, so that it is possible to detect a weld line, an edge of an object of detection, etc. with high accuracy.

    摘要: An operation confirming method capable of making, in order to enhance an operation program correction efficiency, an operation path at an operation confirming time (teaching mode) identical with that at an actual job time (play mode) as much as possible; and a control device therefor. The method comprises the steps of inputting respective shaft operation instruction values (&ohgr;j) based on an actual operation speed to a mechanical simulator-carrying low-speed instruction converter (7), and instructing to a servo controller unit (4) a quantity (&ohgr;ij) (=&ohgr;sj/P), obtained by dividing an output (&ohgr;sj) from the mechanical simulator by a specified positive real number P at the low-speed instruction converter, as respective shaft operation values N times (N; maximum natural number not exceeding the real number P).

    摘要: Approximate straight lines or approximate curves at the instructed points are obtained on the basis of coordinates actually passed by a welding torch at the instructed points in the welding of the first layer, points on the approximate straight lines or approximate curves are calculated on the basis of distance at the instructed points, and actual welding path is defined at the points. In the locus of the second and succeeding layers, a shift direction and a shift amount are obtained by calculation on the basis of two points instructed as a welding start point and a termination point in the teaching of the first layer and two reference points designated to define the shift direction, and the locus of operation after the second layer is calculated to effect multi-layer welding. For controlling the torch attitude in the welding of the second layer and succeeding layers, a locus of operation of a torch in the welding of the first layer and a locus of operation of the second and succeeding layers are obtained on the basis of a torch rotational angle given from the outside, after which the torch is rotated by a portion of a torch rotational angle about the traveling vector obtained at the instructed point, and the attitude data is obtained by calculation. Welding of the second and succeeding layers is carried out on the basis of the obtained attitude data.
