This paper treats the SL robot, a concrete spraying robot for tunnel construction work in mountains. The SL robot is the core of the SL (Spray Lining) system developed by our company as a very efficient concrete spraying method with low dust generation. The SL robot reduces material loss from rebounding as well as the concentration of the generated dust, while the operation characteristics and the safety are superior in comparison to conventional spraying robots.
