摘要: A surface of a workpiece, from which the burr is removed, is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape (S1). This positional data is corrected by an error caused by a bend of a robot (S2). The thus obtained positional data is compared with the target shape of the surface, from which the burr is removed, obtained from CAD data (S6, S10). A shift of the surface shape in the normal line direction is found (S7, S11). The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position (S8), the shift end position and the shift size (S14). A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed (S16, S17). As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed. Due to the foregoing, it is possible to provide a finishing machine characterized in that useless burr removing actions can be reduced and, further, that the overcutting of a workpiece can be prevented.

摘要: An image of a workpiece (10) conveyed by a feeding conveyor (3) is taken by a camera (7) of a visual sensor to detect a position of the workpiece. The moving amount of the feeding conveyor (3) is detected by a pulse coder (8). When a request for picking up a workpiece is issued to a plurality of robots (RB1, RB2), it is judged whether or not the robots can grip the workpiece positioned most downstream, based on current positions of the robots and a current position of the workpiece. The workpiece should be gripped before it reaches the downstream boundary line (TR1e, TR2e) in the tracking range of the robot. If the workpiece can be gripped, the robot picks up the workpiece. Based on the robot operating speed, the feeding speed of the feeding conveyor (3) is adjusted to reduce the waiting time of the plurality of robots (RB1, RB2) and to reduce the number of failures to hold the workpiece as far as possible.

摘要: A calibration device and method for automatically determining the position and the orientation of a robot used for measurement. First, an initial position of a preliminary position is generated based on a designated basic position, and it is judged whether the initial position is within an operation range of the robot. If the robot cannot reach the initial position, the preliminary position is adjusted close to the basic position. Otherwise, the preliminary position is evaluated by calculating an evaluation index of the preliminary position. When the evaluation index does not satisfy a predetermined condition, an initial value of an posture angle is increased.

摘要: A teaching position correcting device which can easily correct, with high precision, teaching positions after shifting at least one of a robot and an object worked by the robot. Calibration is carried out using a vision sensor (i.e., CCD camera) that is mounted on a work tool. The vision sensor measures three-dimensional positions of at least three reference marks not aligned in a straight line on the object. The vision sensor is optionally detached from the work tool, and at least one of the robot and the object is shifted. After the shifting, calibration (this can be omitted when the vision sensor is not detached) and measuring of three-dimensional positions of the reference marks are carried out gain. A change in a relative positional relationship between the robot and the object is obtained using the result of measuring three-dimensional positions of the reference marks before and after the shifting respectively. To compensate for this change, the teaching position data that is valid before the shifting is corrected. The robot can have a measuring robot mechanical unit having a vision sensor, and a separate working robot mechanical unit that works the object. In this case, positions of the working robot mechanical unit before and after the shifting, respectively, are also measured.

摘要: A robot automatically moving a distal end portion of a robot arm to an arbitrary target position, and method therefor. A camera mounted at the distal end portion of the robot arm captures an image of an object. A position R1 corresponding to the target Q is specified in the image. Assuming that the number of pixels between the position R1 and the center of an image screen is equal to N1, a distance W1 observed at a distance L0 at the time of calibration is determined as W1=C0·N1, where C0 is a transformation coefficient. The camera is moved by the distance W1 in an X axis direction toward the target Q. A position R2 corresponding to the target W is specified in the image. The number, N2, of pixels between the position R2 and the screen center is determined. A motion vector q is determined from C0, N1, N2 and L0. The camera is moved according to the motion vector q. The robot is positioned at a position where the camera center is opposed to the target Q at the distance L0. By specifying the target Q in the image, a motion to the specified target Q position is automatically realized.

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.

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.
