A system (100) for handling parts (300) in a press line comprises two industrial robots (101a, 101b) and at least one control unit (400) for the control of the robots, wherein each industrial robot is an articulated robot with at least four axes mounted in series between a robot base (2) and a robot wrist (3), wherein each industrial robot further comprises an arm (4) that has a proximal end (4a) fixed to the robot wrist (3) and a distal end (4b) carrying an additional rotational axis (A7), a motor (43) mounted on the arm near the proximal end, and a transmission (41) between the motor and the additional rotational axis. A method for handling parts in a press line may comprise operating the system such that the two robots jointly handle a part, or such that they each handle a part, either in an alternating or in a parallel mode.

A robot includes: an n-th arm (where n is at least one integer equal to or greater than 1) that includes a first portion and a second portion having a portion extending in a different direction from the first portion and is rotatable around an n-th rotation axis; and an (n+1)-th arm that is installed in the n-th arm to be rotatable around an (n+1)-th rotation axis as a different axis direction from a axis direction of the n-th rotation axis. The second portion is located closer to the (n+1)-th arm than the first portion. The n-th arm and the (n+1)-th arm are overlapable when viewed in the axis direction of the (n+1)-th rotation axis. The n-th rotation axis and the (n+1)-th rotation axis are separate from each other. A length of the (n+1)-th arm is equal to or less than 80% of a length of the second portion.

An articulated robot includes a lumbar portion including a first joint that rotates about a first axis which is a vertical axis and rotating about the first axis, a second joint connected to the lumbar portion and rotating about a second axis parallel to a horizontal plane, a first arm connected to the second joint and rotating about the second axis, a third joint connected to the first arm and rotating about a third axis parallel to the second axis, and a second arm connected to the third joint and rotating about the third axis. When the first arm extends parallel to the first axis, a clearance through which the second arm rotating about the third axis can pass in a planar area between the second axis and the third axis is provided between the second arm and the first arm and between the second arm and the lumbar portion.

In a robot, each of a first flexible member and a second flexible member has a portion fixed to an n-th arm, a portion that is fixed to an (n+1)-th arm, and a portion that is positioned between the n-th arm and the (n+1)-th arm and is wound around a member in a folded state. The portion of the first flexible member that is fixed to the n-th arm is positioned on the member side from the portion of the second flexible member that is fixed to the n-th arm. The portion of the second flexible member that is fixed to the (n+1)-th arm is positioned on the member side from the portion of the first flexible member that is fixed to the (n+1)-th arm.

A bending apparatus in one aspect of the present disclosure comprises a robot, a chuck mechanism, and a plurality of bending mechanisms. The plurality of bending mechanisms are each provided as a separate component from the robot and the chuck mechanism, and are arranged in a space reachable by a workpiece held by the chuck mechanism.

A robot includes a robot arm having an nth (n is an integer equal to or more than one) arm and an (n+1)th arm, the nth arm is rotatable about an nth rotation shaft, the (n+1)th arm is provided on the nth arm rotatably about an (n+1)th rotation shaft in a shaft direction different from a shaft direction of the nth rotation shaft, and, while a distal end of the robot arm is moved from a first point to a second point, a first operation such that the nth arm and the (n+1)th arm overlap as seen from the shaft direction of the (n+1)th rotation shaft and a second operation of rotating the nth arm are performed.

An apparatus for use with a robot may couple to or form part of an appendage, for example a wrist. The apparatus can include a base, a first platform, a second platform, a first set of linear actuators that moveably couple the first platform to the base and a second set of linear actuators that moveably couple the second platform to the first platform. The apparatus can take the form of dual prismatic platforms. A controller can provide control signals to operate the linear actuators to cause the first platform to translate and rotate with respect to the base and to cause the second platform to translate and rotate with respect to the first platform. Connectors can couple the base to an appendage and couple an end effector to the second platform.
