20090003983 | Articulated Robot - An articulated robot having a low lowest posture, a long up-down stroke, and such rigidity that the predetermined positional accuracy can be secured is provided. | 01-01-2009 |
20100199797 | TRANSFER ROBOT, TRANSFER METHOD, AND CONTROL METHOD - A transfer robot includes a hand section on which an object is placed; a horizontal arm mechanism connected to the hand section, the horizontal arm mechanism including at least two rotary joints, the horizontal arm mechanism extending and contracting so as to move the hand section along one direction, the horizontal arm mechanism being disposed so as to face in an axial direction; and a lift mechanism including a link mechanism that moves the horizontal arm mechanism up and down, wherein the lift mechanism includes at least two sets of link mechanisms disposed on a base member, and wherein the horizontal arm mechanism is disposed between parts of the lift mechanism when the horizontal arm mechanism is moved to a lowest position. | 08-12-2010 |
20110123305 | TRANSFER ROBOT - A transfer robot includes a hand section, a horizontal arm mechanism, and a lift mechanism. An object is to be placed on the hand section. The horizontal arm mechanism is connected to the hand section and includes at least two rotary joints. The horizontal arm mechanism is configured to extend and contract so as to move the hand section along one direction. The lift mechanism is configured to move the horizontal arm mechanism up and down and includes a plurality of link mechanisms disposed on a base member. The horizontal arm mechanism is disposed between parts of the lift mechanism when the horizontal arm mechanism is moved to a lowest position. | 05-26-2011 |
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 |
20130085601 | ROBOT SYSTEM - A robot system according to embodiments includes a robot and a control unit. The robot includes a plurality of movable units that operate in a predetermined direction and links connected to the movable units, and the control unit controls an operation of the movable units of the robot. Moreover, the robot system transfers a detachable member mounted on a predetermined movable unit by causing a movable unit other than the predetermined movable unit to operate in a state where the predetermined movable unit is stopped. | 04-04-2013 |
20140140800 | ROBOT ARM, ROBOT AND ROBOT OPERATING METHOD - A robot arm includes an extensible/retractable arm unit, which is configured to extend and retract in a horizontal direction and provided with a pulley arranged in a tip end portion thereof, and a robot hand rotatably connected to the tip end portion of the extensible/retractable arm unit through the pulley. The robot arm further includes a belt drive device including one or more drive power sources, which are arranged close to the robot hand and configured to directly drive a belt wound around the pulley. | 05-22-2014 |
20140140801 | SUBSTRATE TRANSFER ROBOT AND SUBSTRATE TRANSFER METHOD - A substrate transfer robot includes an extensible/retractable arm unit, a robot hand and a sensor unit. The extensible/retractable arm unit is configured to extend and retract in a horizontal direction. The robot hand is provided with prongs for holding a substrate. The robot hand includes a base end portion rotatably connected to a tip end portion of the extensible/retractable arm unit. The sensor unit is arranged to be rotated by a rotating force of the robot hand. The sensor unit is configured to, when rotated, intersect a lateral end portion of the substrate held by the prongs when seen in a plan view and to detect a lateral end position of the substrate. | 05-22-2014 |
