Abstract: A robot includes a robot body, a control processor, a detection circuit, a memory, and a determining circuit. The control processor is configured to control the robot body to perform a work on a workpiece while the workpiece is conveyed. The detection circuit is configured to detect external force which the robot body receives from the workpiece. The memory is to store a threshold force. The determining circuit is configured to determine whether the external force is equal to or larger than the threshold force.

Abstract: A robot in an embodiment includes a robot body, an end effector, a cable, and one or more coupling portions. The end effector is connected to the robot body. The cable is composed of a plurality of sub cables, arranged along the robot body, and connected to the end effector. Each of the coupling portion is provided between one sub cable and an adjacent sub cable of the sub cables to couple the one and adjacent sub cables together.

Abstract: 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.

Abstract: A robot includes: a stage unit; a rotation base connected to the stage unit in a rotatable manner around a predetermined rotating axis; an arm unit connected to the rotation base and having a base end rotatable around a first rotation axis that is substantially orthogonal to the rotating axis; a balancer connected to both the rotation base and the arm unit; and a cable arranged along the arm unit outside the balancer while supported by that balancer.

Abstract: A workpiece positioning device according to an embodiment includes a first moving unit that is movable in a horizontal direction, a second moving unit that is movable in a vertical direction, and a rotating unit that is placed on either an upper end or a lower end of the second moving unit. The second moving unit and the rotating unit are kept within the width of the first moving unit that is perpendicular to the moving direction of the first moving unit on a horizontal plane.

Abstract: An optical element comprises a pair of substrates each having an electrode and bonded together with a gap therebetween and a light adjusting material including a liquid crystal and enclosed in the gap. Each of the pair of substrates has an electrode connecting portion to be connected to an external circuit. At least a part of the electrode connecting portion of each of the substrates is located on the same side as that of the optical element. The electrode connecting portion of one of the substrates and the electrode connecting portion of the other of the substrates have respective electrode portions at regions that are not opposed to each other. The electrode portion of each of the electrode connecting portions is connected to the external circuit.
