    摘要: A robot control system is provided for teaching the distal end position of a working member mounted on a wrist of a robot and executing a predetermined task. A rotational angle is determined by a calculation control unit (/w) from the projection (/w') of a gripping direction vector of a workpiece. A command for correcting the positional rotation of the tool coordinate system is obtained through simple processing based on information indicative of the position of the workpiece from a sensor. As a result, the position of the tool can be rotatively corrected and controlled, even if the gripping direction vector is not parallel to the surface on which the workpiece is placed.

    摘要: There are provided a tracing control apparatus (1), a numerical control apparatus (2), and switching circuits (3X, 3Y, 3Z) for switching and transmitting selectively control instructions from the tracing control apparatus (1) and the numerical control apparatus (2), to a three-axis driving means for the tracer controlled machining (4) and a three-axis driving means for the numerically controlled machining (5) in accordance with selection signals. A numerically controlled machining and tracer controlled machining selection signal (S.sub.C) is used as one of the selection signals besides a tracer controlled machining selection signal (S.sub.A) and a numerically controlled machining selection signal (S.sub.B). When the numerically controlled machining and tracer controlled machining selection signal (S.sub.C) is selected, the three-axis driving means for the tracer controlled machining (4) is controlled by the tracing control apparatus (1), and the three-axis driving means for the numerically controlled machining (5) is controlled by the numerical control apparatus (2), independently. As a result, it is possible to perform the preparation for the tracer controlled machining or the conversion of the tracer controlled machining data into digital information, simultaneously, with the numerically controlled machining.

    摘要: A path correction system of an automatic welding machine has means for differentiating welding current values at respective left and right positions of a torch when weaving is performed, and means for sensing welding current when a value obtained from the differentiating means is zero. The difference is found between welding current values when left and right differentiated values are zero, and the position of the center of the weaving pattern along which the torch advances is corrected based on the difference value.

    摘要: A tool posture control system according to the present invention rotates a tool vector v.sub.1 indicative of a present tool position to a target tool vector v.sup.1 through vector rotation, and generates data for driving robot axes from the data produced by the vector rotation. For a welding robot, for example, the inclination of a torch with respect to an arc starting surface can automatically and appropriately be established, so that an arc starting point can accurately be searched for. Therefore, the operation to search for a desired arc starting point can properly be carried out without human intervention.

    摘要: A method and apparatus for sensing the present position of a movable machine element in a position control system when a position control loop in the system is placed in the open state. In the position control system, error storage means computes and stores an error which corresponds to the difference between a command value produced by a control unit and an amount of movement sensed by a position sensor provided on a motor shaft or on the movable machine element. A speed control circuit controls the motor in accordance with the error from the error storage means. The method of sensing the present position includes the steps of reading and storing the error from the error storage means as a steady deviation immediately before the position control loop is switched from the closed to the open state, reading the error in the error storage means when the position control loop is in the open state, updating the content of a present position register on the basis of an arithmetic difference obtained by subtracting the steady deviation from the error read from the error storage means when the position control loop is in the open state, and revising the content of the error storage means in dependence upon the arithmetic difference.
