    摘要: A robot system can grasp and take out one of a plurality of workpieces placed in a basket-like container by a hand mounted at the forward end of a robot arm. The workpiece is detected by a visual sensor, and the robot is controlled depending on a position and an orientation of the workpiece. When a problem such as interference or the like occurs, information relating to the problem is stored in a robot control unit or a visual sensor control unit. Information relating to the problem includes a predetermined amount of the latest data retrospectively traced from the time point of problem occurrence, a position which the robot has reached, the target position data, the content of the process executed by the visual sensor, and the detection result. When the problem is reproduced, these data are used to simulate the situation at the time of problem occurrence by using simulation unit. The situation at the time of problem occurrence can also be reproduced by using the actual robot without using the simulation unit.

    摘要: Three-dimensional measurement capable of reducing an error in coupling robot and sensor coordinate systems and adverse effects of backlash in a robot. A position/orientation of the robot for obtaining a measurement value on the sensor coordinate system is set beforehand with a workpiece positioned at a reference position. Then, the robot is moved to a preparatory measurement position, a preparatory measurement for the workpiece positioned at an arbitrary position is performed (SV1), and based on a measurement result, a main measurement position is calculated (SV2). Next, an auxiliary position is determined (SV3), which serves as a start position from which a movement to the main measurement position can be made without making a reversal of respective axes. The robot is moved to the auxiliary position (SV4), and to the main measurement position (SV5), and a measurement for the workpiece is made and a measurement result is stored (SV6).

    摘要: A measuring system for easily detecting Misjudged Detection (M/D). A camera for measurement attached to a robot is used to obtain an image for measurement of a workpiece so as to measure and detect a set point. Next, a camera for validation is used to obtain an image for validation of the workpiece so as to measure and detect the set point. One camera may capture both of the images for measurement and validation, by utilizing movement of the robot. It is judged whether the measured results obtained from the images represent the same point on the workpiece or not. If yes, the measured results are judged to be valid, otherwise, the measured results are judged to be invalid and an exception process, such as a retrial, is executed. The images by the camera may also be used for judging a moving path of the robot during measurement of a large object.

    摘要: A work model (or an image) is displayed on an image plane of a robot simulator (201), and a measuring portion and a measuring method are designated (202, 203) and a work shape and a work loading state are designated (204), and then it is judged whether or not the measuring portion and the measuring method are good (205). When the measuring portion and the measuring method are good, a program is generated and the processing is completed (207, 208). When the measuring portion and the measuring method are not good, an alarm is given (206), and the continuation (207) or the repetition (201) of the processing is directed. At the time of analyzing the program, the loading (101), the analysis and display of the measuring portion and the measuring method (102, 103) and the work information (104) are designated, and then it is judged whether or not the measuring portion and the measuring method, which have been analyzed, are good (105). When the measuring portion and the measuring method are good, the processing is finished (107). When the measuring portion and the measuring method are not good, an alarm is given (106), and either the completion of the processing (107) or the correction of the program (201) is selected. Due to the foregoing, a burden imposed for raising and maintaining the visual sensor robot system can be reduced.

    摘要: A three-dimensional visual sensor is disclosed. A two-dimensional image of a two-dimensional feature portion (15) including a point (11) determined on a work (13) is acquired, and N (N≧2) points are determined. A slit of light is projected by a projector (1), an image of a projected portion (19) is obtained, and M (M≧2) points are determined. The three-dimensional position of the intersection point between each straight line connecting the N points and a point in a camera (2) and the slit of light plane is determined on the sensor coordinate system, and transformed to the data on the reference coordinate system (on or parallel to the slit plane). The three-dimensional positions of M points are similarly subjected to coordinate transform to the data on the reference coordinate system. Straight lines (or curves) defined by the M and N points are determined, respectively, by the least squares method. The intersection point between the two straight lines is determined and returned to the data on the sensor coordinate system by inverse transform. The template matching method may alternatively be used for detecting the feature portion. As a result, the measurement accuracy and the reliability are improved for the three-dimensional visual sensor for measuring the three-dimensional position of a specific point by radiating the a slit (or a pseudo-slit) of light on the surface of the object.

    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.
