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.

A reception sectionreceives a classification of a shape of a target object for a case in which a robot is to perform an action along the target object. An instruction sectioninstructs a user with a number of training points identified for each classification of the shape as training points for training positions of a specific location of the robot to perform the action. An acquisition sectionacquires positional information of the specific location of the robot as trained by manipulation by the user according to the instruction. A estimation sectionestimates a shape of the target object based on the acquired positional information. A generation sectiongenerates a path for the robot to perform the action along the target object based on the estimated shape of the target object.

Path generation device and method

A technique automates robotic assembly of two parts with a fastener structure including an engaging portion and a receiving portion. A robot system includes a robot that grips a workpiece, a force sensor located on the robot to measure a force and a moment acting on the workpiece, and a controller that controls the robot. The controller monitors, while moving the workpiece in a direction along a first axis and inserting the workpiece into a part, a change in a force F in the direction along the first axis and a change in a moment M about a second axis perpendicular to the first axis measured by the force sensor to determine a state of assembly of the workpiece with the part.

Teaching including adjustment of an inclination of a suction tool with respect to an object is performed in teaching of a suction position of the suction tool. A sticker affixing system includes an articulated robot, a controller, a suction tool attached to a distal end of the articulated robot, a force sensor, and a storage. The controller causes the articulated robot to execute an operation of bringing the suction tool close to a sticker on a release paper in a teaching mode, an operation of adjusting a suction position of the suction tool and an inclination in a traveling direction (roll axis X) of the suction tool in peeling off the sticker based on a signal from the force sensor, and an operation of storing the teaching data including information about the adjusted suction position and the inclination of the suction tool in the storage.

Multi-hole absorption device for industrial robot arm

In a seal affixing system, adsorption pores are arranged plurally along a first direction and a second direction on an adsorption face, and the plurality of adsorption pores are sectioned into a first suction region, a second suction region, and a third suction region containing a plurality of adsorption pores from a downstream side to an upstream side along a movement direction, and a controller controls a suction power generator to individually suck the first suction region, the second suction region, and the third suction region. According to the seal affixing system, a turbulent spot will not be generated in the affixed seal.

Generation of a wrinkle is prevented when a sticker is affixed to an object. A sticker affixing system includes an articulated robot, a controller configured to control the articulated robot, a suction tool attached to a distal end of the articulated robot, and a force sensor configured to detect force applied to the suction tool. The controller causes the articulated robot to execute: an operation of moving the suction tool holding a sticker along a surface of an object to which the sticker is affixed; and an operation of adjusting an inclination of the suction tool with respect to a traveling direction (roll axis) of the suction tool and the traveling direction of the suction tool based on a signal from the force sensor.
