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 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 according to an aspect of an embodiment includes a robot arm, an attaching portion, an end effector, an end-effector-side cable, and a robot-side cable. The attaching portion is provided on a leading end of the robot arm. The end effector is attached to the attaching portion. The end-effector-side cable extends from the end effector. The robot-side cable is arranged along the robot arm and is connected to the end-effector-side cable by terminal connection at a position closer to the end effector than the attaching portion.
