Abstract: In a case in which a second distance between a future position of a robot and a future position of a person is shorter than a second predetermined distance, a modification unit modifies movement trajectory information such that the second distance is equal to or longer than the second predetermined distance. In a case in which a first distance is shorter than a first predetermined distance, a control unit stops or decelerates a movement of the robot, regardless of whether the movement trajectory information is modified. In a case in which the first distance is equal to or longer than the first predetermined distance and the movement trajectory information is modified, the control unit controls the movement of the robot on the basis of the movement trajectory information after modification.

Abstract: 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.

Abstract: 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.

Abstract: In the present invention, contact between an operator and a robot that moves a workpiece is avoided, and an effect on an article is reduced. This robot controller (1), which controls the operation speed of a robot (2) that moves a workpiece (3), comprises: a prediction unit (11) that predicts contact from the position of a robot and the position of a person or object; and an acceleration change unit (12) that, when contact is predicted by the prediction unit, changes the acceleration at which the speed of the robot is reduced to perform an emergency stop in accordance with the presence of the workpiece.

Abstract: A multi-hole absorption tool includes an absorption surface including a plurality of absorption holes to which a seal is absorbed. Each of the plurality of absorption holes is classified so as to belong to at least one of a first region and a second region, and absorption holes belonging to the first region and absorption holes belonging to the second region are connected to different suction devices. The multi-hole absorption tool having this configuration can peel off the seal from a mount with no wrinkle in the seal, prevent positional displacement of the seal with respect to an object to which the seal is affixed, and affix the seal to the object.

Abstract: A highly reliable determination device to determine the distance to an object even if general-purpose optical distance measurement modules or the like are used. The determination device determines that an abnormality has occurred in at least one of a plurality of optical distance measurement modules when the distances respectively indicated by the optical distance measurement modules deviate from each other by a predetermined length or more.

Abstract: An optical safety sensor is inexpensively implemented. An optical safety sensor includes: a plurality of light projectors/receivers (a first light projector/receiver and a second light projector/receiver), which includes light projecting portions and light receiving portions; distance measurement portions, which measure distances using the time from light projecting to light receiving; and detection portions, which detect, based on measurement results, an abnormality occurring in any one of the plurality of light projectors/receivers; each of the light receiving portion provided in the plurality of light projectors/receivers receives reflected light caused by the light projected from the light projecting portions of all the plurality of light projectors/receivers.

Abstract: A safety monitoring system (1) is provided with: a second sensor (30) for monitoring a second area; a first sensor (20) for monitoring a first area; a first processing unit (100) for detecting an approach of a human (6) to the second area; a second processing unit (200) for detecting an entry of the human into a dangerous area; and a mode determination unit (300). The mode determination unit determines a first mode when an approach of the human to the second area is not detected, and a second mode when an approach of the human to the second area is detected, and the operation differs between the first mode and the second mode.

Abstract: A control system (1) includes: a control device (100) that controls a robot (200); a three-dimensional sensor (300) that acquires positional information of a worker and the robot (200), which are included in a viewing-field area in a three-dimensional space; and a support device (400) that provides a user interface (411) for virtually setting a cooperation region in which the worker and the robot (200) are allowed to work. The control device (100) controls stopping or the speed of the robot (200) on the basis of whether or not the position of the worker or the robot (200) calculated on the basis of the positional information is included in the cooperation region, which is set by using the user interface (411), as well as the relative positional relationship between the worker and the robot (200) calculated on the basis of the positional information.

Abstract: The disclosure is provided to accurately measure a distance to an object. An optical distance measuring sensor includes a light receiving part having a plurality of light receiving elements and receiving reflected light via an optical system. The optical system is configured such that, in the case where an object having a size of a minimum value is arranged in an area within a maximum measurement distance, two or more of the light receiving elements receive the reflected light from the object.
