A robot system includes a robot, a vision sensor, and a controller. The vision sensor is configured to be detachably attached to the robot. The controller is configured to measure a reference object by using the vision sensor and calibrate a relative relationship between a sensor portion of the vision sensor and an engagement portion of the vision sensor, and teach the robot by referring to the relative relationship and by using the vision sensor, after the vision sensor is attached to the robot.

A system includes an information processing device. The information processing device is configured to acquire an image group from each of a plurality of cameras. The image group includes a plurality of images of an object that moves relative to each of the plurality of cameras. The plurality of images are captured by a corresponding camera at predetermined intervals and having different image capture times. The information processing device is configured to calculate an amount of movement of the object relative to each of the plurality of cameras, based on the image group acquired from each of the plurality of cameras. The information processing device is configured to detect a lag between image capture timings of the plurality of cameras, by using the amount of movement of the object relative to each of the plurality of cameras.

A method of controlling a robot system includes measuring, capturing, and calculating. A measuring device attached to the robot measures a position and an orientation of a marker with respect to the robot. An imaging device captures an image of the marker and a workpiece. A control device calculates a relative positional relationship between the workpiece and the robot in accordance with a result obtained by the measuring device and with the image captured by the imaging device.

Method and device of controlling robot system

A robot system includes a robot, a vision sensor, a controller, and an input unit. The vision sensor configured to measure a feature point and obtain a measured coordinate value. The controller configured to control the robot. The input unit configured to receive an input from a user toward the controller. The controller obtains, via the input unit, setting information data on a determination point which is different from the feature point. The robot system uses a coordinate value of the determination point and the measured coordinate value, and determines whether the robot is taking a target position and orientation.

Indicators are set on a marker positioned on a working stage in conformity with a target teaching point. A stereo camera images the indicator in a state of being positioned on a robot hand, and measures the three-dimensional position of the marker. In robot arm controlling, the robot hand is positioned at the correction teaching point for off-line that is offset from an off-line teaching point in the depth of field direction of the stereo camera. In imaging, while the robot hand is positioned at the correction teaching point for off-line, the indicators are imaged by the stereo camera. In correcting, based on an imaging result of the indicator, the on-line teaching point is corrected toward the target teaching point to obtain the on-line teaching point.
