4 conclusion
Construction robot is a new field of cross fusion of robot technology
and construction industry, and its application scope covers every stage
of building life cycle. This paper summarizes the application fields and
key technologies of wall construction robot, decoration construction
robot, maintenance construction robot, rescue construction robot, 3D
printing construction robot, etc. In order to realize the healthy
development of future construction robot, the following characteristics
need to be reflected:
(1) High precision. On the basis of optimizing the trajectory of
structural design and positioning control, multiple sensors and combined
algorithms are integrated to make up for or improve the defects of their
functions, save costs and improve the accuracy of operations. For
example, Michael Albert et al. (2015) change the original positioning
technology and use the laser marking method to integrate multiple laser
sensors. A relatively perfect laser sensor system is formed, which
realizes the accurate positioning of the robot and the cost is low.
(2) Lightweight. Weight has a significant impact on the robot’s
operational functions. The lightweight characteristics of the robot can
be reflected by optimizing the structural design and selecting materials
such as alloy. For example, Yutan Li et al. (2018) optimized the design
of the shell of the CMRR rescue robot based on the maximum stress
formula of the reinforced plate.
(3) Intelligent. We will combine the theories of brain imitation
technology, big data technology, sensing technology, kinematics and
dynamics with the construction industry to develop intelligent building
robots with multiple functions.
