    摘要: An article conveying robot system capable of effectively containing an article in a container conveyed by a conveyor by using a robot. A container detecting part measures the distribution of shading of an image of each containing cell based on a detection result of the container, detects the containing state of each cell, and stores the detection result of each cell. An information managing part of a controller of an upstream side robot receives information from a container detecting part of a controller of a downstream side robot, and then generates containing cell information. An information managing part checks the cell information to be processed, and then transmits the cell information to a task executing part only when an article is not located in the corresponding cell. Task executing part controls the robot so as to locate an article in the selected cell based on the cell information.

    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.

    摘要: A measuring system which can easily measure a three-dimensional position of a target to be measured using a light receiving device mounted to a manipulator of a robot. When the manipulator is positioned at a first position, a moving process for moving an image of the target imaged by the light receiving device or a camera to a center of a light receiving surface of the camera is executed. Next, the manipulator positioned at the first position is moved, without changing the orientation of the camera, to a second position where the distance between the camera and the target is different to that at the first position. After that, the moving process is executed again. Based on the position of the manipulator after the process, the orientation of a coordinate system Σv1 representing the direction of a visual line is calculated. Then, the manipulator is rotated by 180 degree about Z-axis of the coordinate system Σv1 and the moving process is executed again. A middle point of the positions of coordinate system Σv1 before and after movement of the manipulator is determined as an origin of a coordinate system Σv2 representing the orientation and the position of the visual line. The manipulator is inclined relative to Y-axis of the coordinate system Σv2 and the moving process is executed again, so as to calculate the three-dimensional position of the target.

    摘要: A visual sensor capable of expanding a dynamic range with a little load of processing for arithmetic operations and performing a stable detection not affected by change of conditions such as ON/OFF state of projection of reference light. A multiplying parameter A (A>1) and the number N of times of image capturing are set in accordance with ON/OFF state of the reference light projection. N images are captured with a shutter speed varying by successively multiplying an initial value by (1/A). Values of density of each pixel in the captured images are summed. Values of constants B and C in equations: 1=B·Zmax+C; 0=B·Zmin+C are obtained based on the maximum value Zmax and the minimum value Zmin of the summed values of densities of all the pixels. An output value Z′ of each pixel is obtained according to an equation: Z′=B·Z+C, using the determined values of B and C.

    摘要: The image of a tool center point (31) caught by a camera (light-receiving device) 4 from two initial positions is moved to a predetermined point, by a predetermined point moving process, at the center of a light-receiving surface thereby to acquire robot positions (Qf1, Qf2), based on which the direction of the view line (40) is determined. Next, the robot is moved to the position where the position (Qf1) is rotated by 180 degrees around the Z axis of a coordinate system (Σv1) thereby to execute the predetermined point moving process. After rotational movement, a robot position (Qf3) is acquired. The midpoint between the position (Qf1) and the position (Qf3) is determined as the origin of a coordinate system (Σv2). Using the position and the posture of the view line (40), the position of the tool center point (31) is determined. Thus, the position of the tool center point with respect to the tool mounting surface can be determined using a fixed light-receiving device. By additionally measuring two points at known relative positions from the tool center point, the tool posture as well as the position of the tool center point can be determined.
