    摘要: An apparatus for controlling an articulated robot comprises coordinate transforming portions (5 to 8 and 18) and a calculating portion (9) for equation of motion. The coordinate transforming portions (5 to 8 and 18) perform coordinate transformation between the Cartesian coordinate system and the articular system with respect to the position data, speed data, acceleration data and force data. The coordinate transforming portions (5 to 8 and 18) are respectively formed of hardware and accordingly, the calculation speed therein is extremely high as compared with the case using software. The calculating portion (9) for equation of motion solves the inverse problem of an equation of motion using the speed data (d.alpha.) and acceleration data (d.sup.2 .alpha.) in the articular coordinate system, whereby predictive control is performed. The calculating portion (9) for equation of motion is also formed of hardware and accordingly, the calculation speed therein is extremely high. In addition, the above described controlling apparatus further comprises a force feedback loop, so that the RCC (Remote Center of Compliance) can be realized in the arms per se of a robot.

    摘要: Velocity, at which a work point of a robot passes through respective reference points, has previously been given magnitude and directions dependent on a relative positional relation between a plurality of continuous reference points. The work point passes through the respective reference points. Between adjacent reference points, interpolation arithmetic is performed along the above condition, whereby the work point defines a smooth locus in accordance with the result of the arithmetic.

    摘要: An increment type position control apparatus is adapted to evaluate a numerical value concerning a positional point by making subtraction between the data in a position feedback counter for counting a feedback pulse from an incremental encoder and the data in a commanded position buffer from a processor. Upon depression of an origin return command button provided on a control panel, the position feedback counter and the commanded position buffer are each loaded with a predetermined value, whereupon a pitch is given, whereby an object being controlled is controllably moved in the direction toward the origin. If and when the object being controlled exceeds the origin position, the same is stopped and the counter and the buffer are each again loaded with an appropriate numerical value, whereupon a given pitch is provided, whereby the object being controlled is moved in the direction toward the origin and comes to a point to almost exceeding the origin position. Just at the timing when the object being controlled is about to pass the origin position, the position feedback counter is set, whereby the data concerning the origin is regained in the apparatus.

    摘要: The present invention belongs to the field of techniques related to a laser robot and a method of controlling the same, particularly for performing weaving of a laser beam easily with high accuracy without the provision of a vibrating condenser lens at the leading edge of an arm.To solve the problems, in the laser robot (RB) of the present invention, a first inclined mirror (41a) is mounted on a motor (42a) inclined at a predetermined angle from a plane perpendicular to the direction of the rotation axis of a rotor shaft. Similarly, a second inclined mirror (41b) is mounted on a motor (42b) inclined at a predetermined angle. The laser beam (LB) emitted from a laser oscillator (8) is reflected in series by the first and second inclined mirrors (41a, 41b) and is subsequently propagated in the laser robot (RB) to be directed toward workpieces from the tip of a torch (7). By controlling the numbers of rotations, rotation directions and rotation phases of the first and second inclined mirrors (41a, 41b), weaving modes of the laser beam (LB) are selected.
