20090114052 | ARTICULATED MANIPULATOR - This invention provides a manipulator that can facilitate a teaching method, improve the operation speed of an arm, and mount a heavy load in a narrow space. The manipulator includes a plurality of arm bodies provided in series, joint parts rotatably connecting two adjacent arm bodies, and the joint parts in which slope of rotation axes of the adjacent joints are 90 degrees, at least one linear body disposed in the joint parts coaxially with the rotation axes. The joint parts are composed of a servo motor, and a speed-reduction mechanism. The rotation axes of the servo motor, the speed-reduction mechanism and the joint parts become the same axis. | 05-07-2009 |
20100229671 | INDUSTRIAL ROBOT - The present invention provides an industrial robot, wherein a cable or the like spanned between an end effector and an upper arm has less bending due to a motion of a wrist portion, wherein the cable or the like does not twine around the upper arm, and wherein the cable or the like does not interfere with a peripheral device. | 09-16-2010 |
20110219906 | ARTICULATED MANIPULATOR - An articulated manipulator includes a base body, a first arm body, a second arm body having a second arm center axis, and a third arm body. A first joint part connects the base body and a first end portion of the first arm body rotatably around a first rotation axis. A second joint part connects a second end portion of the first arm body and a third end portion of the second arm body rotatably around a second rotation axis. A third joint part connects a fourth end portion of the second arm body and a fifth end portion of the third arm body rotatably around the third rotation axis. When the first, second and third arm bodies are all erected with respect to a installation surface, the first rotation axis, the second arm center axis, and the third rotation axis are substantially aligned with each other. | 09-15-2011 |
20130025399 | ROBOT AND METHOD FOR MANUFACTURING THE SAME - A robot according to an aspect of an embodiment includes: an articulated arm; and a speed reducer that is provided in a joint of the articulated arm. The articulated arm performs a multi-axis operation. The speed reducer has rigidity for which an acquisition value obtained by acquiring a deflection amount of a predetermined representative position at the articulated arm for each dimension of a three-dimensional coordinate system is not more than a threshold corresponding to a target precision of the articulated arm. | 01-31-2013 |
20140283642 | ROBOT - A robot includes a link having a longitudinal base end rotatably connected to a member so as to rotate about a rotation axis perpendicular to a longitudinal direction of the link. The link is formed into a tubular shape such that a cross section of the link perpendicular to the longitudinal direction has an elliptical shape or a substantially rectangular shape with at least one curvilinear corner portion. | 09-25-2014 |
20150081095 | ROBOT - Provided is a robot further improved in safety. The robot includes at least one link which is rotatably coupled around an axis, a motor which rotates the link around the axis, a first sensor which detects a rotation state of the motor, and a second sensor which detects a rotation state of the link. The robot also includes a controller which controls the rotation of the link based on information from the first sensor. The controller determines an operation state of at least one of the first sensor and the second sensor, based on first information from the first sensor and second information from the second sensor. | 03-19-2015 |
20150081096 | ROBOT AND ROBOT SYSTEM - A robot is provided with a base to be fixed to an installation surface, and an arm unit having a plurality of arm bodies sequentially and revolvably coupled with each other with one end coupled to the base through a joint unit. The arm unit has a stopper mechanism having a movable stopper member capable of restricting a revolving motion of the arm bodies to a predetermined revolving range. The movable stopper member is provided to one link of one of the pairs of links coupled through the joint unit, whereas the fixed stopper member, which is engaged with the movable stopper member, is provided to another link of the one of the pairs of links. | 03-19-2015 |
20160031093 | ROBOT - A robot includes a lower arm, an upper arm, an actuator, and a brake. The upper arm is supported by the lower arm, and includes a bottom portion having a through hole and an arm portion extending from the bottom portion avoiding the through hole. The actuator includes an output shaft and a rotor coupled thereto. The brake is installed on the end surface of the actuator opposite to the side from which the output shaft projects and acts on a part of the rotor to brake the actuator. Virtual space is obtained by parallel displacement of a region corresponding to the through hole in the extending direction of the arm portion. The actuator is installed on the arm portion on the side of the virtual space, with the posture of the actuator being such that the virtual space and the brake do not overlap each other. | 02-04-2016 |
20160036301 | ELECTRIC ROTATING MACHINE - An electric rotating machine includes an electric rotating machine body that cause a rotating body to rotate around an output axis, a rotation detecting device that detects rotation of the rotating body, and a braking device that stops rotation of the rotating body. The rotation detecting device includes a rotating portion that rotates in association with the rotating body. The rotating portion is arranged coaxially with the output axis. The braking device is arranged at a position shifted from the output axis of the rotating body. | 02-04-2016 |
