20150013492 | ROBOT - A robot includes a body, a first arm, and a second arm. The first arm includes one joint, an adjacent joint that is adjacent to the one joint, and another adjacent joint that is adjacent to the adjacent joint. When the first arm is extended in a vertical orientation relative to the body, the one joint of the first arm has a rotation axis that is offset by a first distance in a first horizontal direction from a rotation axis of the adjacent joint of the first arm, and the another adjacent joint of the first arm has a rotation axis that is offset by a second distance in a second horizontal direction from the rotation axis of the adjacent joint of the first arm. The first horizontal direction is opposite to the second horizontal direction. | 01-15-2015 |
20150012133 | WORKING ROBOT AND ROBOT SYSTEM - The working robot includes a plurality of link members coupled rotatably around shafts, a motor driving the link members, and a controller switching a state of use of winding wires of the motor based on a result of sensing a moving object including a human in a predetermined area. The controller switches the state of use of the winding wires of the motor, to drive the link members in a first mode in which the number of revolutions or the torque of the motor is relatively large, when the moving object is not present; and switches the state of use of the winding wires of the motor, to drive the link members in a second mode in which the number of revolutions or the torque of the motor is relatively small, when the moving object is present. | 01-08-2015 |
20150008691 | SUCTION STRUCTURE, ROBOT HAND AND ROBOT - A suction structure includes a fixing base, a pad, and a support body. The pad includes a contact portion which makes contact with a target object to be sucked. The support body is installed to the fixing base and the support body is configured to elastically support the pad. Further, the pad and the support body define an inner space, and the fixing base includes a suction hole which brings the inner space into communication with a vacuum source. | 01-08-2015 |
20150008690 | SUCTION STRUCTURE, ROBOT HAND AND ROBOT - A suction structure includes a fixing base, a pad, and a support body. The fixing base includes an annular wall portion. The pad includes a contact portion which makes contact with a target object to be sucked. The support body is installed on an inner circumferential surface of the annular wall portion, and the support body is configured to elastically support an outer circumferential surface of the pad at a lateral side of the pad. Further, the pad and the support body define an inner space, and the fixing base includes a suction hole which brings the inner space into communication with a vacuum source. | 01-08-2015 |
20150008689 | SUCTION STRUCTURE, ROBOT HAND AND ROBOT - A suction structure includes a pad and a fixing base. The pad includes a contact portion which makes contact with a target object to be sucked and which has a seal wall, and a major surface portion which is surrounded by the contact portion and which defines an inner space in conjunction with the seal wall as the contact portion makes contact with the target object. The fixing base includes a support portion configured to support the pad at a position offset from the center of the major surface portion of the pad, and a suction hole configured to bring the inner space into communication with a vacuum source. | 01-08-2015 |
20150008688 | SUCTION STRUCTURE, ROBOT HAND AND ROBOT - A suction structure includes a pad and a fixing base. The pad includes a contact portion which has a seal wall and makes contact with a target object to be sucked, a major surface portion which is surrounded by the contact portion and defines an inner space in conjunction with the seal member as the contact portion makes contact with the target object, and a thin portion formed in the major surface portion. The fixing base includes a suction hole configured to bring the inner space into communication with a vacuum source and supporting the pad. | 01-08-2015 |
20140375243 | MOTOR CONTROL DEVICE - This disclosure discloses a motor control device including a main circuit, a voltage detector, and a controller. The controller includes a position controller and a speed controller, The position controller generates a speed command The speed controller generates a torque command and controls a inverter based on the torque command Further, the controller includes a torque limiter, and a speed matching instruction part. The torque limiter starts torque limiting by the torque command to a predetermined torque or less and cancels the torque limiting. The speed matching instruction part matches the speed command with a first position command speed after the cancellation of the torque limiting. The holding part calculates and holds an accumulated position deviation. | 12-25-2014 |
20140373662 | ROBOT, METHOD FOR PRODUCING ROBOT, AND COVERING - A robot includes a robot arm, a robot hand, and a covering. The robot hand is disposed on the robot arm. The covering covers at least a part of the robot hand. | 12-25-2014 |
20140367559 | MOTOR WITH ENCODER - A servo motor includes a motor including a shaft and a bracket on an opposite side of a load side, a disk connected to the shaft and having a plurality of reflecting slits formed along a circumferential direction, a light source configured to emit light to the reflecting slit, a light-receiving element configured to receive light emitted from the light source and reflected by the reflecting slit, a substrate provided with the light source and the light-receiving element, an encoder cover attached to the bracket so as to cover the disk and the substrate, and a support member provided on the encoder cover. | 12-18-2014 |
