2.2 Development status of domestic construction robot
There are few researches on building robots in China, which mainly focus on exterior wall cleaning of high-rise buildings and automatic installation of building construction, such as the curtain wall cleaning robot of high-rise buildings developed by Jiangxi University of Science and Technology (Ganghong,Xu.,2017), and the installation robot of indoor panels under the 863 project (Fei,Tian.,2015), etc. Among them, the high-rise curtain wall cleaning robot developed by Jiangxi University of Science and Technology integrates movement, cleaning and adsorption, which is composed of four parts: roof auxiliary machine device, cleaning device, vacuum sucker adsorption device and driving device. After a series of tests, the robot can realize the speed of 0.3 m2/s mobile cleaning; The mechanism of indoor plate installation robot under 863 project is mainly hybrid type, and the space required by its work is judged by the combination of Monte Carlo method and section method. Experiments have proved that the robot can achieve accurate installation of 50 kg plate, with a repetition accuracy of 0.5 mm.
To sum up, construction robot technology is still in the stage of exploration and research and development, and has not been widely used in the construction industry. Moreover, the construction industry has a clear division of labor, which leads to the targeted development of construction robots. At present, many areas of the construction industry has not appeared the figure of the building robot, such as pipeline maintenance robot, line maintenance robot. In order to solve these problems effectively, it is still necessary to introduce a large number of related robot technology to fill this gap.
