  • Patent number: 8295975
    Abstract: An object picking device, which is inexpensive and capable of speedily and accurately picking one object at a time from a random pile state. A target detecting part of an image processing part processes an image captured by a camera and detects objects. A target selecting part selects an object among the detected objects based on a certain rule. A view line direction calculating part calculates the direction of a view line extending to the selected object. A target position estimating part estimates the position including the height of the selected object based on size information of the object in the image. Then, a grip correction calculating part calculates an amount of correction of the movement of a robot so as to grip the object by using the robot.

  • Patent number: 8014899
    Abstract: 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.
