  • Patent number: 9102059
    Abstract: A robot control method includes a first step of selecting a holding form in which a robot holds an object and a second step of determining whether the object can continue to be stably held when a predetermined external force is applied to the object in the selected holding form. In the second step, it is determined that the object can continue to be stably held when a force which should be generated by a contact portion to generate resistance to the predetermined external force is included in a friction cone of a force generated by driving the contact portion and enlarged by a suction force from the suction mechanism.

  • Patent number: 8942845
    Abstract: A robot includes a gripping section and a main body section to which the pair of finger sections are attached, having one end sections of the pair of finger sections rotatably connected to each other around a first rotating shaft disposed at a position separate from the main body section, and adapted to open and close the pair of finger sections by swinging the other side of the pair of finger sections on a plane parallel to a mounting surface on which an object is mounted centered on the first rotating shaft to thereby grip the object, a moving device adapted to relatively move the object and the gripping section, and a control device adapted to control the moving device to move the gripping section relatively toward the object, and grip the object with the gripping section at at least three contact points.

  • Patent number: 8622452
    Abstract: A recess has a proximal-end-side surface and a distal-end-side surface. When an intersection between a straight line included in the proximal-end-side surface and a straight line included in the distal-end-side surface is a base point, a line passing through the base point is a base line, a line between two claw portions, passing through an end point of the recess and orthogonal to the base line is an orthogonal line, the angle ? made between the base line, and the straight line included in the distal-end-side surface is greater than 0 degrees and less than 90 degrees, the angle ? made between the orthogonal line, and the straight line included in the proximal-end-side surface is greater than 0 degrees and less than 90 degrees, and the length d from the base point to the orthogonal line is greater than 0.

  • Patent number: 8287017
    Abstract: When dishes are held by means of a robot hand (10), its fixed side engaging plate (13) and movable side engaging finger (14) are moved under horizontal state toward a dish (20) to be handled, and the outer circumferential edge side portion of the dish (20) is inserted between them. The distal end portion (14b) of the movable side engaging finger (14) is then bent by a predetermined amount to the side of the dish (20) and the robot hand (10) is raised. Consequently, the dish (20) is brought into a state where it is held by its own weight between the fixed side engaging plate (13) and the movable side engaging finger (14). Thereafter, the right and left first finger units (15, 16) are bent to the side of the dish (20) and the dish (20) is pushed by their dish pushing faces (15g, 16g), thus bringing about such a state as the dish (20) is held surely between the fixed side engaging plate (13) and the movable side engaging finger (14).

  • Patent number: 8272828
    Abstract: An object moving apparatus is provided which is different from coordinated conveyance through real-time information exchange between carriages only by wireless communication and which can move an object reliably and in a more stable manner by coordinated control of carriages without the object falling off. Arranged is a leader carriage A with a carriage body 2 travelable in all directions by travel drivers 1 and a lifter 5 attached to the carriage body via a link mechanism 3 for lifting up a vehicle 4 as object. The leader carriage is movable along a given target track. Further arranged is a follower carriage B with a carriage body 2 travelable in all directions and a lifter 5 attached to the carriage body via a link mechanism 3 for lifting up the vehicle 4. The follower carriage estimates and follows movement of the leader carriage so as to move the vehicle 4 in coordination with the leader carriage.
