20080257092 | PARALLEL-LINK OPERATIONAL DEVICE - A parallel-link operational device in which links of a link mechanism connecting rotary actuators and a movable member do not protrude outside an area of a base. Six flat rotary actuators driven to control position and posture of the movable member are provided on the base, rotary output shafts of which are disposed radially pointing toward the center of the base. The links fixedly mounted on the rotary output shafts of the actuators are connected by joints to one end of rods, and the other end of the rods are connected to the movable member by joints. An end effector mounted on the movable member is rotated by an actuator for posture control mounted on the base via a rotational-force transmission mechanism composed of joints, spline couplings, etc. The links rotate in planes parallel to the sides of the base without protruding beyond the area covered by the base. | 10-23-2008 |

20090025199 | FLEXIBLE WORKPIECE ASSEMBLING METHOD - A flexible workpiece assembling method for assembling a flexible workpiece (W) with an object by using a first robot comprising a first hand and a second robot comprising a second hand includes the steps of: gripping a first portion of the flexible workpiece by the first hand and gripping a second portion of the flexible workpiece different from the first portion by the second hand; moving the flexible workpiece to the object through a cooperating operation of the first and second robots; deforming the flexible workpiece into a shape corresponding to the nonflexible object by the first and second robots; and assembling the flexible workpiece onto the nonflexible object by the first and second robots. As a result, the flexible workpiece can be accurately assembled onto the nonflexible object without breaking or tearing. The first and second robots may comprise a pushing means for pushing the flexible workpiece into the object. | 01-29-2009 |
20090084927 | INDUSTRIAL ROBOT - An industrial robot capable of being decomposed into multiple units at the time of conveyance of the robot and being conveyed individually in units: wherein each of the units has a holding bracket for conveyance means to hold the unit in order to convey the unit. | 04-02-2009 |
20090088898 | ROBOT CONTROLLER FOR HALTING A ROBOT BASED ON THE SPEED OF A ROBOT HAND PORTION - A robot includes a traveling rail supported by struts, and a robot body attached to a slider that slides on the traveling rail. A robot controller comprises speed calculation means for calculating moving speeds of the robot hand portion on the coordinate axes of a rectangular coordinate system set for the robot controller; comparator means for comparing the moving speeds on the coordinate axes calculated by the speed calculation means with threshold values on the coordinate axes of the rectangular coordinate system, respectively; and halting means for halting the robot in case at least any one of the moving speeds is higher than the corresponding threshold value. The strength required for the struts can be lowered without limiting the dynamic capability of the robot. | 04-02-2009 |
20100028117 | ROBOT SYSTEM USING ROBOT TO LOAD AND UNLOAD WORKPIECE INTO AND FROM MACHINE TOOL - A robot includes a base member, which is installed at a position offset from the front of a door of a machine tool to the side, as viewed in a direction vertical to the surface where the door is provided and is fixed to a surface of a base slanted so as to face the door side. A rotary member is coupled to the base member so as to be rotatable about a first axis extending vertical to the slanted surface. A first arm member is coupled to the rotary member so as to be able to swivel about a second axis vertical to the first axis, and a second arm member is coupled to the first arm member so as to be able to swivel about a third axis parallel to the second axis. | 02-04-2010 |
20100191372 | PRODUCTION SYSTEM HAVING COOPERATING PROCESS AREA BETWEEN HUMAN AND ROBOT - A production system in which a human and a robot may simultaneously perform a cooperative task in the same area while ensuring human's safety. A robot is positioned at one side of a working table, and an operator is positioned at the other side of the working table. The reachable area of the operator is limited by the working table. An area of the working table is divided into an area where only the operator may perform a task, an area where only the robot may perform a task, and an area where both the operator and the robot may enter. In a cooperation mode, the maximum movement speed of a component of the robot is limited lower than when the component of the robot is outside the cooperative task area, and, the motion of the robot is limited so that the robot does not enter a robot entry-prohibited area. | 07-29-2010 |
20110257785 | ROBOT SYSTEM - A robot system including a robot arm driven by a servo motor; and a robot controller controlling an operation of the robot arm. The robot system further comprises a first detection section detecting a rotation amount of the servo motor; a second detection section attached to a tip portion of the robot arm, and detecting a velocity or acceleration of the tip portion of the robot arm; a computation section computing the velocity or acceleration of the tip portion of the robot arm based on values detected by the first detection section, and computing a deviation between this computed velocity or acceleration and the velocity or acceleration detected by the second detection section; and an emergency stop section for bringing the servo motor to an emergency stop when a magnitude of the deviation computed by the computation section is greater than a reference value. | 10-20-2011 |
