  • Publication number: 20230219231
    Abstract: A target object setting unit sets a position of a target object in a work object. A feature point recognizer detects feature points of a work object from a captured image obtained by an image capturing apparatus, the image including the work object and a holdable object. A first position calculator calculates a position of the target object in a coordinate system of the image capturing apparatus based on the feature points. A second position calculator calculates a position of the holdable object in the coordinate system of the image capturing apparatus based on the captured image. A control signal generator converts the positions of the target object and the holdable object in the coordinate system of the image capturing apparatus, into positions in a coordinate system of the robot arm apparatus, and outputs a first control signal to the robot arm apparatus based on the converted positions of the target object and the holdable object, for moving the holdable object to the position of the target object.

  • Patent number: 10596484
    Abstract: A packing has a plurality of sheet materials spaced and arranged in parallel, and liquid flows along the flat surface thereof in a standing use state. Each sheet material has at least one member group including a plurality of support members arranged such that the upper end of the uppermost support member corresponds to the upper end of the sheet material and the lower end of the lowermost support member corresponds to the lower end of the sheet material. Each support member has a pair of support walls parallel to the liquid flow direction and perpendicular to the sheet material surface, and a bridging part connecting the support walls. A sandwiching structure is formed that one sheet material is held by at least one support member attached thereto and at least one support member attached to an adjacent sheet material, and it extends linearly through the plurality of sheet materials.
