    摘要: Upon reception of a work sensing command from a robot controller, an image processing unit obtains a two-dimensional image of thee whole work pallet including a work, with a CCD camera (a first sensor means). A line of sight is calculated based on the work position on the sensed two-dimensional image. The robot controller determines the destination of movement of the robot such that a crossing line LC of slit beams LB1, LB2 of a laser sensor (a second sensor means) can agree with the calculated line of eight. The image processing unit operates the laser sensor so as to surely irradiate the laser slit beams LB1, LB2 to the target work, permitting the laser sensor to sense the three-dimensional positional and orientation of the target work.

    摘要: A workpiece is gripped and unloaded by moving workpiece unloading means based on the results of measuring the workpiece position and orientation with a visual sensor. When a plurality of loaded workpieces are unloaded in a regular order one by one, or in groups, the position and orientation of the workpiece which is to be unloaded next change for each unloading. However, since a visual sensor is moved when necessary to the position appropriate for measuring the workpiece position and orientation, measurements of the workpieces with the visual sensor are conducted accurately. Therefore, the workpiece unloading is conducted reliably.

    摘要: A laser machining apparatus with a simplified laser beam transmitting network. Respective laser beams form laser generators LS#11 to LS#25 divided into groups of G1 and G2 are aggregated to fiber-optic cables H1 and H2 by confluence devices HC1 and HC2 and transmitted to a most upstream laser beam outlet OP1. The laser beams are further aggregated to a fiber-optic cable H3 and distributed to a branch fiber-optic cable HH1 by the laser beam outlet OP1, and then distributed by laser beam outlet OP2 to OP8 to branch fiber-optic cables HH2 to HH8. The laser beams distributed to branch fiber-optic cables are focused by the machining tools TL1 to TL8 attached to robots RB1 to RB8 for laser machining. By controlling output levels of the laser generators with different oscillation wavelengths and different polarization characteristics, blend ratio of the laser beams can be adjusted. Distribution ratios of the laser beams at the laser beam outlets OP1 to OP8 are adjustable.

    摘要: A method of setting a coordinate system to an automatic machine with a stable accuracy in a non-contact manner. The desired coordinate system can be set even if it exists outside a moving range of the automatic machine. The operator operates a robot control device to move a robot to a first position A1 where a coordinate system setting jig is within the field of view of a camera supported by the robot. Matrix data [A1] representing the robot position A1 is stored and the jig is photographed by the camera. The image of a group of dots on the jig are analyzed by an image processor to obtain picture element values of the individual points. Based on the picture element values of the individual points and jig data (data of distances between and number of the points), matrix data [D1] representing a position and a posture of a coordinate system &Sgr;c to be set with respect to a sensor coordinate system &Sgr;s is obtained. In the same manner, a matrix data [D2] at a position A2 is obtained. According to a relationship [C]=[A1]·[S]·[D1]=[A2]·[S]·[D2], a matrix [C] is derived and stored as data for setting the coordinate system &Sgr;c to the robot control device.

    摘要: A robot coordinate system setting method is provided which facilitates the setting of a common coordinate system with respect to each of robots in a robot system or a robot installed in substitution for one of the robots. A coordinate transformation matrix for transforming a provisional coordinate system (X2Y2Z2), which a first robot has recognized by accessing a second jig, into a common coordinate system (X1Y1Z1), which the first robot has recognized by accessing a first jig, is calculated, and using this coordinate transformation matrix, a provisional coordinate system which a second robot has recognized by accessing the second jig is transformed into the common coordinate system which is to be recognized by the second robot, and is set with respect to the second robot. If a robot is installed in substitution for the second robot, method similar to the above is used to obtain a second provisional coordinate system, which the substitute robot has recognized by accessing the third jig, and is transformed into the common coordinate system which is to be recognized by the substitute robot, whereby the common coordinate system is set with respect to the substitute robot.

    摘要: After a calibration process has been carried out once for a sensor with respect to a certain position, the position of an object can be detected by the sensor in any other positions, so that the object can positionally be detected in a wide range. Specifically, calibration data (CDA) (32) is produced by calibration process in a position A before a camera moves, and calibration data (CDB) (33) for the camera after it is moved is calculated based on distance data CM (12) with respect to the position and attitude of the camera (3). Then, the position of an object (30) is detected on the basis of the calibration data (CDB) (33) and image data (WDB) (31) of the object (30) imaged by the camera (3) which is in the position B.

    摘要: A method for automatically effecting calibration between an image processing apparatus and a control device of an automatic machine. Jig data for calibration and the position of a robot, fitted with a jig which can be photographed by a camera at the time of calibration, are previously given as instructions. In response to a calibration command, the robot, fitted with the jig, moves to a point of instruction, the image processing apparatus photographs the jig and fetches an image after the movement. A calibration process is executed in accordance with data of the photographed image, set jig data, and robot position. When the jig data and the instruction point are first set and given once as instructions, the calibration thereafter can be automatically effected only by mounting the jig on the robot and inputting the calibration command.

    摘要: To simply correct the positional data in the teaching program for the robot at a stable precision. The working tool (such as a spot welding gun 13 or others) is mounted to an arm of the robot 10 and imaging means 14 is detachably attached to the arm by a magnet 17 or others so that the optical axis coincides with the working direction (the opening/closing direction of the gun 13). When the positional data correcting program starts, the points P1 to P3 on the jig 1 or the workpiece 2 are imaged at a plurality of image positions D1, D2 and D3, and the position of the respective point is detected. Based on the detected result, the correction is made on the positional data in the teaching program, corresponding to the deviation (in comparison with the off-line data or positional data prior to the transfer of the system) of position and posture of the jig 1 (or the workpiece 2). The tool may be a laser beam machining nozzle, an arc welding torch or a sealing gun.
