Abstract: A conveying device includes a first link that includes a first connecting part, a second connecting part, and a first holder part located opposite the second connecting part with respect to the first connecting part, a second link that includes a third connecting part rotatably connected with the first connecting part, and operates to rotate the third connecting part about a first reference point, a third link that includes a fourth connecting part rotatably connected with the second connecting part and operates to rotate the fourth connecting part about a second reference point, and a first drive that operates the links. The links move the first holder part between a first point and a second point opposite each other with respect to the first reference point so that the first holder part approaches the first reference point in association with operation of the second link.

Abstract: A processing method includes one or both of a first processing and a second processing for extracting a reference teaching point from teaching points. The first processing extracts a reference teaching point having a difference between a direction vector from a teaching point preceding the reference teaching point to the reference teaching point, and a direction vector from the reference teaching point to a teaching point succeeding the reference teaching point, being equal to or more than a threshold. The second processing extracts the reference teaching point having one of a difference between a posture at a teaching point preceding the reference teaching point and a posture at the reference teaching point, and a difference between the posture at the reference teaching point and a posture of a teaching point succeeding the reference teaching point, being equal to or more than a threshold.

Abstract: A robot system includes a robot including an end effector, an operation unit, and a controller which moves the end effector based on operation of the operation unit and causes the end effector to perform processing to a to-be-processed surface of a workpiece in a contactless manner. When moving the end effector based on the operation of the operation unit, the controller performs at least either one of a first control in which a distance between the end effector and a control to-be-processed surface, which is the to-be-processed surface of the workpiece or an imaginary to-be-processed surface of the workpiece, is constant, or a second control in which an angle of the end effector with respect to the control to-be-processed surface is constant.
