20150245972 | FINGER JOINT DRIVING DEVICE - A finger joint driving device is provided on a hand and causes a finger joint to be turned. The finger joint driving device includes a first base portion that is mounted on the hand, a first link portion that is turnably provided on the first base portion, a second link portion that is turnably provided on the first link portion, a second base portion that is mounted on the end side of a finger from the first base portion in the hand and is provided on the second link portion so as to relatively approach with respect to and to be separated from the first base portion, and a driving unit that drives the second link portion to be turned. | 09-03-2015 |
20150265412 | DRIVE DEVICE - A finger joint drive device includes a first base section disposed on a back of a hand, a second base section rotatable with respect to the first base section, a drive section adapted to rotate the second base section, and an attachment mechanism. Further, the attachment mechanism is provided with a first curved portion having contact with a palm of the hand in an attached state, and a second curved portion and a third curved portion adapted to connect the first curved portion to the first base section. The first curved portion is arranged along a life line in the attached state. Therefore, the finger joint drive device can stably be fixed to the hand, and the degree of freedom of the fingers can sufficiently ensured. | 09-24-2015 |
20150266184 | FORCE DETECTION DEVICE AND ROBOT - A force detection device includes a first base unit, a second base unit that is arranged along a first direction with respect to the first base unit, a sealing member that is disposed in a section where the first base unit and the second base unit overlap each other when viewed in a second direction orthogonal to the first direction, and that forms a closed space with the first base unit and the second base unit, and a piezoelectric element that is disposed inside the closed space. The Young's modulus of the sealing member is higher than the Young's modulus of the first base unit and the Young's modulus of the second base unit. | 09-24-2015 |
20150342818 | DRIVING DEVICE AND DRIVING METHOD - A driving device includes a wearable mechanism that is worn on a wearing part, an actuator that drives the wearable mechanism, and first and second force sensors that are provided on the wearable mechanism and detect a force. The first and second force sensors are provided at positions at which a first detected value obtained from the first force sensor and a second detected value obtained from the second force sensor are changed in response to a motion of the wearing part. When a difference between the first and second detected values is less than a pre-decided first threshold value and the first or second detected value is greater than a pre-decided second threshold value, the actuator drives the wearable mechanism so that the second detected value is constant. | 12-03-2015 |
20150349665 | PIEZOELECTRIC ACTUATOR AND ROBOT - A piezoelectric actuator according to an embodiment includes a piezoelectric element, a vibrating plate including a main body section provided with the piezoelectric element, a fixing section, and a coupling section that couples the main body section and the fixing section, and a first member to which the vibrating plate is fixed. The fixing section is fixed to the first member by sandwiching the fixing section with the first member and a second member. In the thickness direction of the vibrating plate, each of the thicknesses of the first member and the second member is larger than the thickness of the fixing section. When viewed from the thickness direction of the vibrating plate, the main body section has a pair of sides opposed to each other. The vibrating plate includes a plurality of the coupling sections on one of the pair of sides of the main body section. | 12-03-2015 |
20160049574 | PIEZOELECTRIC DRIVING DEVICE, ROBOT, AND DRIVING METHOD OF THE SAME - A piezoelectric driving device includes a vibrating plate, and a piezoelectric vibrating body including a substrate, and piezoelectric elements provided on the substrate. The piezoelectric element includes a first electrode, a second electrode, and a piezoelectric body, and the first electrode, the piezoelectric body, and the second electrode are laminated in this order on the substrate. The piezoelectric vibrating body is installed on the vibrating plate so that the piezoelectric element is interposed between the substrate and the vibrating plate. A wiring pattern including a first wiring corresponding to the first electrode and a second wiring corresponding to the second electrode is formed on the vibrating plate, the first electrode and the first wiring are connected to each other through a first laminated conducting portion, and the second electrode and the second wiring are connected to each other through a second laminated conducting portion. | 02-18-2016 |
20160074179 | DRIVING APPARATUS AND DRIVING METHOD THEREFOR - A driving apparatus includes a base member, and a first member rotatably provided on the base member. The first member is rotatable about a rotation shaft along an index finger metacarpal bone of a hand when the base member is placed on a back of the hand. | 03-17-2016 |
20160114492 | ROBOT - A robot includes a first arm unit and a second arm unit. The robot includes a first drive part provided within the first arm unit and rotating the first arm unit about a first axis, and a second drive part provided within the first arm unit and rotating the second arm unit about a second axis. At least one of the first drive part and the second drive part contains a piezoelectric body. | 04-28-2016 |
