Japan’s Shimizu Co., LTD developed the world’s first construction robot in the 1980s, namely the SSR-1 refractory spraying robot (Hong, Ma.,2015). In the following decades, construction robot has been attached great importance by all countries in the world, and has been rapidly developed and applied in engineering to a certain extent. According to the different functions of construction robots, they can be divided into wall construction robots, decoration robots, maintenance robots, rescue robots and 3D printing construction robots. This paper systematically summarizes the application fields and key technologies at home and abroad from the aspects of mechanical structure and control system.
