Abstract: A three-dimensional shape measuring instrument is provided for measuring a three-dimensional shape of the polishing subject face. A polishing controller is provided for controlling a polishing robot alone or with a polishing tool, based on three-dimensional shape data of the polishing subject face obtained by the shape measurement by the three-dimensional shape measuring instrument. The polishing tool provides a polishing action on the respective part of the polishing subject face through controlling of the polishing robot alone or with the polishing tool by the polishing controller. By controlling a measuring robot and the three-dimensional shape measuring instrument by the polishing controller, the three-dimensional shape measuring instrument moves to a predetermined measuring position relative to the polishing subject face to measure the three-dimensional shape of the polishing subject face.

Abstract: In an automatic polishing system configured such that under control of a polishing robot and/or a polishing tool by a polishing controller, the polishing tool provides a polishing action on a polishing subject face, a color intensity measurement instrument is provided for measuring an intensity of a specified color in the polishing subject face. Based on the intensity of the specified color measured by this color intensity measurement instrument, the polishing controller controls the polishing robot and/or the polishing tool, so that an amount of polishing work by the polishing tool onto the polishing subject face is adjusted according to the intensity of the specified color.

Abstract: Provided is an automatic teaching system that is readily able to achieve automation, even when a small but varied number of processing objects are to undergo polishing or coating. The automatic teaching system includes a three-dimensional shape measurement apparatus, a reference marker, an image analysis apparatus, and a robot control device. The three-dimensional shape measurement apparatus acquires shape data of a processing target region on a processing object relative to the reference marker, and the image analysis apparatus divides the shape data of the processing target region into a plurality of continuous reference surfaces, in accordance with a predetermined algorithm, automatically generates a program of an operation path along which a polishing apparatus or coating apparatus of the robot is to be operated, for every reference surface, in accordance with a predetermined operation path generation rule, and transmits the program of the operation path to the robot control device.

Abstract: Provided is surface treatment system for a large object having high versatility. In a surface treatment system for a large object configured to cause a treatment machine for treating a surface of the object to be held by a leading end portion of a work arm of a work robot and to move the treatment machine relative to the surface of the object by a movement of the work robot thus treating the surface of the object by the treatment machine, there is provided a trackless type work machine mounting the work robot on a self-propelled cart. The work machine mounts a robot moving device for moving the work robot relative to the self-propelled cart at least in a height direction and mounts also a battery capable of supplying traveling power for the self-propelled cart.

Abstract: Provided is an automatic polishing system that allows a polishing treatment of an article while circumventing a polishing averting portion of the article. A polisher is attached to a leading end portion of a movable arm of a work robot. A control device controls the work robot and the polisher, based on position information of a polishing target surface of an article, so that the polisher is moved along the polishing target surface by a movement of the work robot while providing a polishing action on the polishing target surface at the same time. An image of the article including an image of an area demarcation marker annexed to the article for demarcating the area of the polishing target surface is captured by a three-dimensional image capturing machine. The control device produces the position information of the polishing target surface by determining the position of the area demarcation marker based on image data of the image.

Abstract: Provided is a system controlling method that improves versatility of a surface treatment system. In the treatment system, for treating a surface of an object by a treatment machine while moving the treatment machine relative to the surface of the object by an action of a work robot, there is provided a trackless type work machine mounting the work robot on a self-propelled cart; and the work machine mounts a robot moving device for moving the work robot relative to the self-propelled cart at least in a height direction. A work area in which the object and the work machine are present is image-captured by a position determination camera. A control device recognizes relative positional relation between the object and the self-propelled cart based on image-captured data of the position determination camera and controls the self-propelled cart based on the recognized relative positional relation, whereby the work machine is moved to a designated work position near the object.
