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.
