A screw tightening system includes an actuator including a driver bit that rotationally drives a screw and a motor coupled with driver bit, and a controller that controls actuator. Controller includes an acquirer that acquires torque values of a torque generated in a motor, a calculator that calculates a standard deviation of the torque values in a temporary tightening period, and a determiner that determines that there is an abnormality when a ratio of the standard deviation to a reference standard deviation exceeds a first threshold value.

Screw tightening system, controller, and non-transitory storage medium

Generation of a wrinkle is prevented in a sticker when the sticker is peeled off from a release paper. A sticker affixing system includes an articulated robot, a controller that controls the articulated robot, a suction tool attached to a distal end of the articulated robot, and a sticker feeder that conveys a release paper. The suction tool is sucked to the sticker on the release paper. The controller causes the articulated robot to execute an operation of moving the suction tool in parallel with the release paper at a constant speed of the release paper in synchronization with the sticker feeder, an operation of peeling off the sticker at an edge A of a peeling base of the release paper, and an operation of affixing the sticker to the object to which the sticker is affixed.
