  • Publication number: 20120323358
    Abstract: A picking system includes a conveyer, a robot, a main camera, and a control device. The conveyer conveys workpieces. The robot performs a holding operation and a moving operation on the workpieces. The main camera captures the transport path of the conveyer. The control device detects the workpiece on the basis of the image captured by the main camera and instructs the robot to perform the holding operation on the detected workpiece. Moreover, the control device instructs the robot to perform the holding operation on the overlapped workpieces when the overlapping of the workpieces is detected.

  • Publication number: 20120323357
    Abstract: A picking system includes a conveyer, a robot, and a control device. The conveyer conveys workpieces. The robot includes a plurality of holding parts and a supporting part. The holding parts hold the workpieces. The supporting part is rotatably provided against an arm to support the plurality of holding parts. Then, the control device instructs the robot to rotate the supporting part by a predetermined amount in such a manner that the direction of the workpiece becomes a predetermined direction for each the workpiece held by the holding parts and then to place the workpiece on a predetermined place.

  • Publication number: 20120323363
    Abstract: A robot system according to embodiments includes a conveying device, a plurality of robots, an image capturing device, a workpiece detecting device, and a control device. The control device includes an operation instruction unit and an allocating unit. The operation instruction unit generates an operation instruction for performing a holding operation on workpieces on the basis of the detection result of the workpiece detecting device and transmits the operation instruction to the robots. The allocating unit determines which of the plurality of robots to which the operation instruction unit transmits the operation instruction on the basis of conveying situations of the workpieces obtained from the detection result of the workpiece detecting device.

  • Publication number: 20110098859
    Abstract: A robot system includes a robot. A robot control device is configured to control an operation of the robot, and includes a workpiece shape memory configure to store a shape of workpieces. A shape sensor is configured to detect shape information about the workpieces. A target workpiece detector is configured to detect a graspable workpiece based on the shape information detected by the shape sensor. A grasping information memory is configured to store a grasping position indicating which portion of the graspable workpiece is to be grasped by the robot. A grasping operation controller is configured to control the robot to grasp the graspable workpiece detected by the target workpiece detector and to pick the grasped workpiece. A disturbing operation controller is configured to control, if no graspable workpiece is detected by the target workpiece detector, the robot to perform a workpiece disturbing operation.
