Abstract: A robot system of the present disclosure includes: a robot including an operable working arm driven by an actuator; an operation load detection unit configured to detect an operation load of the actuator; a region setting unit that sets a region with a predetermined range around the robot; a moving body detection unit configured to detect a position of a moving body other than the robot; and an abnormality determination unit that determines abnormality when detecting of the position of the moving body within the region, wherein the region setting unit changes the range of the region in accordance with the operation load of the actuator.

Abstract: A robot system is provided, which includes a robot having an operable operation arm, an attachment detector for detecting one or more attachments, each attached to a wearing article equipped by a movable body, and a motion-control changer for changing a motion control of the robot based on a detection result detected by the attachment detector.

Abstract: A robot includes a first arm, a second arm, and a controller. A first hand is mounted to the first arm. The first hand is configured to hold a tool that is configured to perform a predetermined kind of work with respect to a workpiece. A second hand is mounted to the second arm. The second hand is configured to hold the tool. The controller is configured to control the first arm and the second arm to perform a switching operation of switching the tool from one arm among the first arm and the second arm holding the tool to another arm, so as to control the tool to make a circumferential movement around the workpiece.

Abstract: A robot system includes a robot, a controller, a workbench, and a workpiece component supplier. The robot includes a body, a first arm, a second arm, a first hand, and a second hand. The robot is configured to transfer at least one of a plurality of types of workpiece components from the workpiece component supplier to the workbench by simultaneously holding each of the plurality of types of workpiece components with the first hand of the first arm and the second hand of the second arm. The robot is configured to transfer remaining types of workpiece components among the plurality of types of workpiece components from the workpiece component supplier to the workbench by holding each of the remaining types of workpiece components with only one of the first hand of the first arm and the second hand of the second arm.
