Spraying work in mountain tunnel was under the dust environment of the concrete, and I thought approach technology by automation was needed to the Tatsuki work of the small diameter tunnel with which I'm dealing this time for which correspondence will be necessary immediately from the angle of the worker protection, and the pilot model was developed and it was studied basically, so it's introduced.
