20110222999 | INDUSTRIAL ROBOT - An industrial robot includes a hand on which a workpiece is placed, an arm that takes out the hand from a predetermined position of the workpiece and supplies the hand, an up-down moving mechanism connected to the arm by a support member, a pedestal provided at a lower portion of the up-down moving mechanism, and a pendulum stopper provided on a base on which the pedestal turns. | 09-15-2011 |
20130039730 | ROBOT - A robot includes a rotating electrical machine and a brake. The brake is configured to restrict rotation of the rotating electrical machine. The brake includes a brake plate, a plurality of pressing members, at least one biasing member, and an electromagnetic coil. The brake plate is configured to rotate integrally with a shaft of the rotating electrical machine. The plurality of pressing members are movable toward the brake plate and include a first pressing member and a second pressing member. The at least one biasing member is configured to bias the first pressing member and the second pressing member toward the brake plate using mutually different biasing forces. The electromagnetic coil is configured to, when current is on, electromagnetically attract the first pressing member and the second pressing member against the biasing forces of the at least one biasing member. | 02-14-2013 |
20130046409 | ROBOT AND ROBOT SYSTEM - A robot according to embodiments includes a speed reducer, a first shaft, a rotary electric machine, a second shaft, and a brake. The speed reducer reduces and outputs rotation to be input into an input unit. The first shaft is connected to the input unit. The rotary electric machine rotates the first shaft. The second shaft is connected to the input unit. The brake regulates the rotation of the second shaft. | 02-21-2013 |
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 |
