A control device controls a robot in which a sensor is disposed, the control device comprising: a sensor coordinate storage unit for storing coordinate system information of a sensor coordinate system; a sensor setting storage unit for storing setting information; a sensor data receiving unit for receiving sensor data; an axis angle detection unit for detecting an angle of each of a plurality of axes included in the robot; a sensor value estimation unit for estimating a sensor value to be detected; and an anomalous sensor value determination unit for comparing the value of the sensor data and the sensor value estimated by the sensor value estimation unit and determining that the sensor data receiving unit is receiving sensor data from a sensor of another robot if the difference between the value of the sensor data and the estimated sensor value exceeds a preset threshold value.

Control device

A sensor bracket is provided with frame members supporting an acceleration sensor, the frame members having circular arc members holding an outer periphery of a tool of a robot in a state in which circumferential-direction gaps are defined in at least one portion of the circular arc members in a circumferential direction, and a bolt thread-screwed into the frame members so as to reduce the circumferential-direction gaps.

Sensor bracket and robot system

A vibration display device including a vibration acquisition unit that acquires a vibration state of a distal end section of a robot that is a robot in a simulation or in a real world, the distal end section being moved based on an operation program, and a vibration trajectory drawing unit that draws, on a display device, the vibration state along a trajectory of the distal end section of the robot or that draws, on the display device, the vibration state as the trajectory.

Vibration display device, operation program creating device, and system

The automatic machine includes a movable member driven by a motor, a tool that is attached to the movable member and includes a movable mechanism that operates independently of the movable member, a sensor that is attached to the movable mechanism and measures a location of the movable mechanism, and a processor configured to detect, based on a location of the movable mechanism measured by the sensor when the motor is controlled in accordance with a command to move the tool to a target location and on an amount of movement of the movable mechanism from a reference point, detects a first location in a case in which the movable mechanism is virtually fixed to the reference point, and calculate a correction amount for a control amount of the motor in such a way as to decrease a difference between the target location and the first location.

Automatic machine and control device

A machine learning device is provided in a versatile controller capable of inferring command data to be issued to each axis of a robot. The device includes an axis angle conversion unit calculating, from the trajectory data, an amount of change of an axis angle of an axis of the robot, a state observation unit observing axis angle data relating to the amount of change of the axis angle of the axis of the robot as a state variable representing a current state of an environment, a label data acquisition unit acquiring axis angle command data relating to command data for the axis of the robot as label data, and a learning unit learning the amount of change of the axis angle of the axis of the robot and the command data for the axis in association with each other by using the state variable and the label data.

Controller and machine learning device

A device that can prevent a decrease in an efficiency of a manufacturing line. The device includes a shape acquisition section for acquiring a shape of a workpiece; a motion pattern acquisition section for acquiring basic motion patterns including a reference workpiece shape, a reference working position in the reference workpiece shape, and a type of an operation carried out on the reference working position; a similarity determination section for determining whether a shape of the workpiece is similar to the reference work piece shape; a position determination section for, based on a shape of the workpiece and the reference workpiece shape, determining the working position on the workpiece that corresponds to the reference working position; and an motion-path generation section for, by changing the reference working position to the determined working position, generating a motion path.

Device, system, and method for automatically generating motion path of robot

A shape recognition device that recognizes a shape of an object having an indefinite shape and flexibility, and assembled by a robot, the shape recognition device including: an imaging unit that images the object; an image processing unit that recognizes the shape of the object on the basis of the object imaged by the imaging unit; and a simulation processing unit that simulates the shape of the object on the basis of the image of the object imaged by the imaging unit. The simulation processing unit interpolates a recognition result of the shape of the object by the image processing unit, on the basis of a simulation result of the shape of the object.
