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： 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： 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 production system in which a human and a robot may simultaneously perform a cooperative task in the same area while ensuring human's safety. A robot is positioned at one side of a working table, and an operator is positioned at the other side of the working table. The reachable area of the operator is limited by the working table. An area of the working table is divided into an area where only the operator may perform a task, an area where only the robot may perform a task, and an area where both the operator and the robot may enter. In a cooperation mode, the maximum movement speed of a component of the robot is limited lower than when the component of the robot is outside the cooperative task area, and, the motion of the robot is limited so that the robot does not enter a robot entry-prohibited area.

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.
