  • Patent number: 9283680
    Abstract: A workpiece detector includes a camera to acquire a two-dimensional image of a search range within which workpieces are disposed. A three-dimensional sensor detects a three-dimensional shape of a three-dimensional detection area. A workpiece extraction section processes the two-dimensional image to extract candidate workpieces. An area setting section sets a three-dimensional detection areas respectively corresponding to the candidate workpieces. A prioritizing section sets an order of priority to the three-dimensional detection areas to give higher priority to one three-dimensional detection area containing more of the candidate workpieces. A sensor control section controls the three-dimensional sensor to detect the three-dimensional shape of each three-dimensional detection area in the order of priority. Every time the three-dimensional shape is detected, a workpiece detection section searches the workpieces based on the detected three-dimensional shape to detect a pickable workpiece.

  • Publication number: 20150039129
    Abstract: A robot system includes a robot, a container, a determinator, a motion controller, a torque limitter, and a stirring operation controller. The robot includes a drive source for driving a joint part and an end effector. The determinator determines whether a workpiece capable of being held by the end effector exists among workpieces accommodated within the container. The motion controller controls a motion of the drive source. When the determinator determines that there is no workpiece capable of being held by the end effector, the torque limitter limits a motion torque of the drive source. The stirring operation controller allows the motion controller to perform a stirring operation, by which the workpieces accommodated within the container are stirred by the end effector, in a state where the motion torque is limited by the torque limitter.

  • Patent number: 8725285
    Abstract: A workpiece in a container is held by a robot based on a result of detection of shape information in the container by a shape sensor, a holding condition of the workpiece held by the robot is inspected by an inspection device, and the workpiece is transferred to a subsequent step by the robot when the inspection device has determined that the holding condition of the workpiece is acceptable. When the inspection device has determined that the holding condition of the workpiece is unacceptable, the held workpiece is placed on a temporary placement table, the shape of the workpiece is again detected by detecting the workpiece using the shape sensor, and the workpiece is held and transferred to the subsequent step by the robot based on a result of the detection.
