Abstract: This robot includes a robot arm, a controller which controls the robot arm, an operation panel which sends a control signal to the controller, a camera which is provided in the operation panel and which captures images of an operator who operates the operation panel, a determination means which determines whether or not the operator is looking at a surface of the operation panel on which an operation portion is provided on the basis of the images captured by the camera, and a limitation means which limits motion of the robot arm when it is determined that the operator is looking at the surface or when it is determined that the operator has continuously been looking at the surface.

Abstract: An image processing method for improving the reliability of an industrial visual sensor, in which image data picked up by a camera of the visual sensor are marked with flags such as data for specifying the image data or a detected value for the image data, program name, calibration data, correction data, etc., and are stored in an auxiliary storage device. After a production line is stopped, the image data having so far been stored in the auxiliary storage device are successively invoked to a frame memory of the visual sensor in accordance with the flags. An image processing program is reproductively executed for the invoked image data. Then, established teaching data are checked for reliability, and the cause of a failure in image data detection, if any, is examined, with reference to the information displayed on a monitor screen.
