A view of an affordable housing construction site in eastern Shenzhen’s Pingshan District. Intelligent construction technologies are being used to build these high-rise residential buildings. The robots being used in the construction process include eight types of large-scale application robots, nine types of point application robots, and specialized high-altitude exterior wall-spraying robots. The light-weight machines, which resemble “blue hats” atop the buildings, are central to the vertical construction process, methodically moving upwards to extend the buildings towards the sky.         Liu Yujie
