An object of the present invention is to ascertain parts of an object that are approachable by finger portions of a hand mechanism. In an image information processing device, a housing container is retrieved from an image by using a first retrieval frame, and an object is retrieved from the image by using a second retrieval frame. A plurality of determination points are set in advance on the second retrieval frame, and a predetermined approach direction is set for each determination point. A determination is then made as to whether or not the finger portions of the hand mechanism can be caused to approach parts of one object, existing within the second retrieval frame, that correspond respectively to the determination points set on the second retrieval frame from the predetermined approach directions set in relation to the determination points.

Image information processing device, gripping system, and image information processing method

Robot arm apparatus

In order to extend a life span of a flexible cable passing through a movable portion, provided is a hand mechanism which has a plurality of fingers and grips an object with the fingers, including: a flexible cable; a joint which flexes or extends with the grip of the object, has a path for the flexible cable, and has a first surface and a second surface that is a surface bending from the first surface at a bending portion in the path; and a sheet which is provided between the first surface and the flexible cable to have flexibility and is formed such that a gap is provided between the second surface and the sheet.

Hand mechanism

In a picking mechanism for picking four or more columnar objects, when the plurality of objects have been picked, the objects are respectively held by holding member and supported by guide members while arranged on a base member in a plurality of rows, wherein a total sectional area of the guide members provided in regions of the base member that are each surrounded by circumferences of four circles serving as projections of four objects is smaller than a total sectional area of the guide members provided in regions of the base member that are each surrounded by one or two sides of a virtual rectangle, the virtual rectangle being formed so as to surround all of a plurality of circles serving as the projections of all of the plurality of objects while contacting the circumferences of the plurality of circles, and two or one of the projections.

Picking mechanism and robot arm

A hand mechanism grips an object more favorably, regardless of the attitude and surrounding conditions of the object. When an object is to be gripped by a hand mechanism having three or more finger portions, at least one finger portion among the three or more finger portions functions as a state-altering finger portion for altering the attitude or the position of the object while contacting the object, and at least two finger portions among the finger portions other than the finger portion functioning as the state-altering finger portion function as gripping finger portions for gripping the object in a state where the attitude or the position has been altered by the state-altering finger portion.

Hand mechanism, gripping system, and non-transitory storage medium

A horizontal period counter 3 determines one bit period of bi-phase codes by measuring the period of a horizontal scan line immediately preceding one containing bi-phase codes to be decoded. An edge pulse generator 6 generates edge pulses at rising and falling edges of inputted bi-phase codes. A compensating pulse generator 7 is triggered by the edge pulse and generates a compensating pulse in a predetermined period, which is shorter than one bit period of the bi-phase codes and longer than one half bit period, according to one bit period that has been determined. A rise judging circuit 11 generates sampling pulses by superimposing compensating pulses on the edge pulses. The bi-phase codes are decoded according to the sampling pulses.
