A robot system includes a robot and a motion control unit. The robot includes a bottom, a swiveling base, first to third arms. A bottom side of the first arm is supported on the swiveling base swivelably around a horizontal-direction second axis. A bottom side of the redundant arm is supported on a leading side of the first arm swivelably around an axis parallel to the second axis. A bottom side of the second arm is supported on a leading side of the redundant arm swivelably around a third axis parallel to the second axis. A bottom side of the third arm is supported on a leading side of the second arm rotatably around a fourth axis perpendicular to the third axis. The motion control unit activates the redundant arm so that a control point provided on the fourth axis linearly moves while maintaining a direction of the fourth axis.

Robot system

A bending apparatus has (a) a first manipulator which feeds a hollow metal blank of closed cross section in its lengthwise direction, (b) a second manipulator which supports a first support means disposed at a first position and a metal blank while feeding it, a heating means disposed at a second position downstream of the first position in the blank feed direction for heating all or part of the circumference of the blank, and a cooling means disposed at a third position downstream of the second position for cooling a portion of the heated blank, and (c) a third manipulator which constitutes a second support means disposed at a fourth position downstream of the third position in the feed direction of the blank and which moves two-dimensionally or three-dimensionally while supporting at least one location of the metal blank to bend the metal blank into a desired shape.

Method for manufacturing a bent member

A machining apparatus includes a robot including a first arm portion, a second arm portion, a tip portion, a second actuator swinging the first arm portion around a second axis, a third actuator swinging the second arm portion around a third axis, a seventh actuator adjusting a distance between the second axis and the third axis, and an end effector provided to a tip portion and applying machining to a workpiece. The robot is positioned such that a movable range of a tip portion of the first arm portion or a base end portion of the second arm portion interferes with the workpiece when the first arm portion is rotated around the second axis, where the distance is made longest, in a state where the robot exactly faces the workpiece.

Machining apparatus and method of producing workpiece

A robot system includes an end effector, a robot arm, and a controller. The end effector includes a pressure roller and a linear motion mechanism. The linear motion mechanism is configured to move the pressure roller with respect to a pressed surface. The robot arm is configured to support the end effector. The controller is configured to control the linear motion mechanism to move the pressure roller to make a pressing force of the pressure roller against the pressed surface approximately uniform.

Robot system and method for producing to-be-processed material

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.

Robot
