    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 workpiece taking-out apparatus performs snap with a camera of a three-dimensional visual sensor in a robot position for snap and captures an image in a personal computer. The workpiece taking-out apparatus detects workpieces to find a line of sight of the camera for each workpiece, decides an area for height measurement by a range finder to save height data in the area, and finds an intersection of line of sight data of the camera and height distribution for each detected workpiece to find a posture of the workpiece from the height data around it. Then, the workpiece taking-out apparatus decides a workpiece to be taken out this time from the position and the posture and decides a measurement position of the three-dimensional visual sensor close to the workpiece. In the measurement position, the workpiece taking-out apparatus performs main measurement by the three-dimensional visual sensor to decide a robot position for taking out a workpiece through check of the possibility of interference and execute taking-out of the workpiece in the robot position for taking out a workpiece through check of the possibility of interference again.

    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 method for executing calibration without having to dismount a force sensor from a robot, and an apparatus for executing this method are provided. When a robot mounted with a calibrated force sensor begins to be operated, any tool whose position of the center of gravity and weight are immune from change is fitted, and a command for acquiring reference data is given to execute operational programs. Reference data V0 of matrices consisting of differences between strain gage outputs (S1, S2) of the force sensor in any predetermined posture and strain gage outputs in other predetermined postures differing both from that posture and from one another are calculated and stored (S3-1 to S7). When the measuring accuracy of the force sensor drops, the tool used when the reference data were acquired is mounted on the robot, and the same procedures S1 to S6 are executed, and the data V0 corresponding to the reference data are calculated. From the data V′0 and the reference data V0 is calculated a parameter M for updating the calibration matrices.

    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 workpiece gripping device includes a primary catching mechanism having a suction pad adapted to hold a workpiece by suction power and a rod-like part having the suction pad mounted on one end thereof, gripping pawls sandwiching and gripping the workpiece, a drive unit for supplying a drive power, and a transmission mechanism transmitting the drive power of the drive unit to the gripping pawls. The transmission mechanism moves the gripping pawls along an axis of the rod-like part between a gripping position where the gripping pawls are projected beyond the suction pad and a retreated position where the gripping pawls are retreated from the suction pad toward the base plate. The gripping pawls are moved to the gripping position along the axis of the rod-like part while shortening the distance between the gripping pawls.
