Abstract
New work system by the robot technology to dismantle the interior materials of office building in its renewal was proposed. The dismantlement of ceiling where the amount is the largest in the interior was made an object of the study, and problems in the traditional work method and needs of the site were clarified. And the work system that dismantle the main materials of ceiling board, illuminator, and air-conditioning equipment, etc. by the cooperation of human and robot was developed. ID tag was put on materials, and the work plan by the robot and the control of the robot were supported. Not to damage the light gauge steel of the groundwork and to remove only the board efficiently, the cutting method by the water jet was introduced. To prove the effect of the developed system, the experiment by the mock-up was executed.
