  • Patent number: 8801063
    Abstract: A robot hand is provided, the robot hand including three finger sections, a supporting section which supports a proximal end of each of the three finger sections, and a circumferential movement section which circumferentially moves a second finger section and a third finger section of the three finger sections about a position where the three finger sections are supported on the supporting section is provided. The circumferentially moving second finger section and third finger section are circumferentially movable in a range of 180 degrees or greater in a circumferential direction substantially around a hand axis of the robot hand, about the position where the three finger sections are supported on the supporting section.

  • Publication number: 20140214202
    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.

  • Publication number: 20140103676
    Abstract: A robot hand includes a finger unit that includes a first knuckle section that is supported to a predetermined base section and a second knuckle section that is supported to the first knuckle section; a drive section that includes a male screw that is rotatable around a predetermined screw axis by a predetermined drive source and a female screw that is screw-coupled with the male screw and moves in an axial direction of the screw axis according to rotation of the male screw, in which the female screw and the first knuckle section are connected to each other so that the first knuckle section moves in association with movement of the female screw; and a link section that connects the first knuckle section and the second knuckle section so that the second knuckle section moves in association with movement of the first knuckle section.

  • Patent number: 8585111
    Abstract: A robot hand includes a first finger unit and a second finger unit, a driving unit that causes the finger units to perform an opening and closing action, and a finger-unit moving mechanism that changes a direction in which the opening and closing action of the first finger unit and the second finger unit is performed. The finger-unit moving mechanism includes a worm wheel, a motor, and a worm. A first gear that rotates in a direction different from the rotating direction of the worm in association with the rotation of the worm is provided in the first finger unit. A second gear that rotates in a direction opposite to the rotating direction of the first gear in association with the rotation of the worm is provided in the second finger unit.

  • Publication number: 20120201448
    Abstract: A robotic device includes an imaging section adapted to take an image of an object having a hole, and generate an image data of the object including an inspection area of an image of the hole, a robot adapted to move the imaging section, an inspection area luminance value detection section adapted to detect a luminance value of the inspection area from the image data, a reference area luminance value detection section adapted to detect a luminance value of a reference area adjacent to the inspection area from the image data, and a determination section adapted to determine a state of the inspection area based on one of a ratio and a difference between the luminance value of the inspection area detected by the inspection area luminance value detection section and the luminance value of the reference area detected by the reference area luminance value detection section.

  • Patent number: 7974412
    Abstract: A communication system includes a transmission device that transmits an information signal having information defined as a binary state value, the transmission device including a signal generation unit that generates an information decryption signal to transmit the information decryption signal together with the information signal, wherein the state value of the information decryption signal is unchanged when the state value of the information signal is changed, whereas the state value of the information decryption signal is changed when the state value of the information signal is unchanged; and a reception device that receives the information signal and the information decryption signal, the reception device including an information acquisition unit that acquires the state value of the information signal based on a changing timing of the state value of each of the information signal and the information decryption signal received.
