1 Introduction
In recent years, the world economic situation has been in a depressed
state, and all countries are looking for an economic breakthrough to
stimulate economic recovery and growth. In this context, Germany
officially launched the ”Industry 4.0” strategy combined with ”Internet
+ manufacturing” at Hannover Messe in 2013.(Tseng,M.L.,2018), and other
countries have put forward industrial strategies in line with their
national conditions based on their own characteristics.
China has now fully entered the aging stage, the quantity and quality of
the labor force are declining, and the particularity of the construction
industry, for example: belongs to the labor-intensive industry, many
working procedures rely on the cooperation of many people; It is a
high-risk industry. According to the statistics of accidents above large
level in all industries in 2016 by the National Bureau of Statistics,
the number of accidents and casualties in the construction industry is
second only to the transportation industry, and far higher than other
industries; It is an industry with intensive demand for resources, and
the traditional manual operation is too extensive, so the construction
quality can’t be effectively controlled. Therefore, we put forward the
”building 4.0” strategy.(Xia, Zh -ao.,2015), that is, combining with the
characteristics of the construction industry, the introduction of
industrial robot technology, forming targeted construction robots, this
strategy is an effective way to solve the above problems in the
construction industry.
At present, the development of building robots is still in the initial
stage and has not yet formed a unified large-scale production. This
paper analyzes the application status of the existing wall construction
robot, decoration building robot, maintenance building robot, rescue
building robot and 3D printing building robot, and summarizes the
relevant key technologies. It points out the development direction of
the key technologies of building robots in the future, that is, the
realization of building robots with high precision, light weight and
intelligence.
