摘要： A group of bolts are suppled into a placing surface of a tray, an isolated bolt is searched for by a visual sensor, and its deviation from a standard position at the time of teaching is determined. The isolated bolt is picked up by a robot that has been taught how to pick up an isolated bolt laying in a standard position. The position of the robot's hand is corrected according to the deviation from the standard position before the robot attempts to pick up the located isolated bolt. If no isolated bolt is found, a shaking device 1 is operated to loosen the piled-up bolts, and a new isolated bolt is again searched for by the visual sensor. The isolated bolt, if found, is picked up. The picking-up operation may be performed by searching for an isolated small set of bolts using a three-dimensional visual sensor. The oscillating excitation can also be provided by a robot. Also, the piled-up bolts may be loosened or disentangled using a robot equipped with a tool for leveling the pile of bolts or by using a gas jet.

摘要： A robot controller capable of finding a mistaught path and avoiding dangers involved in a real motion of a robot without using an off-line simulation system. An operation program for confirming safety is played back with the robot control system arranged such that a simulation function is on, a real motion is off, and comparison processing is on. When a played-back path designated by each block is compared with a reference path using data on interpolation points, an interpolation point ordinal index i is incremented by “1” (K1), an interpolation point on a reference path Tref(i) is read (K2) and compared with a corresponding interpolation point on the played-back path T(i). An index of distance d(i) and a distance evaluation index &Dgr;d(i) are calculated (K3, K4), and tool-tip orientation difference indices f(i) to h(i) and orientation-evaluation indices &Dgr;f(i) to &Dgr;h(i) are calculated (K5, K6). Based thereon, it is determined whether or not there is a path difference exceeding a reference value. The processing may be started with a real motion in an on-state, and the real motion of the robot may be nullified when a large path difference is found.

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 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： 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 workpiece is gripped by a robot hand and an image of the workpiece is captured by a camera. An image processing device detects the position and posture of a characteristic portion of the workpiece. On the basis of the present position of the robot, the relative position and posture between a flange of the robot and the workpiece characteristic portion is detected. The relative position and posture is compared with that observed when the workpiece is gripped correctly, to determine a gripping error. If the gripping error exceeds a permissible error, the robot is stopped. If the gripping error is equal to or less than the permissible error, a taught position where the workpiece is to be released is corrected so as to cancel the adverse effect of the gripping error.

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： An image of a reference object is captured using a camera and displayed. A measurement starting point is pointed by an image position pointing device. A corresponding view line is obtained using a position on the image and a position and a direction of the camera, a robot approaches to the reference object such that it does not deviate from a projecting direction to move to a position suitable for measurement. A light is projected on the reference object and measurement of an inclination of a face of the object in the vicinity of a measuring point is started. An image including a bright line image on the reference object is photographed and 3-dimensional positions of points sequentially measured along a working line. A movement path of a robot is created using these positions as teaching points for a working robot.
