BEIJING -- Chinese startup Yingxing Zhineng is hoping to expand its curtain wall-cleaning business overseas four years after developing robots using artificial intelligence to do the job.
Spotting a gap in the market, the company started building and developing the robots in 2016. Curtain walls, which are outer coverings of buildings that are typically aluminum-framed and can be made of glass, are used in 5% of high-rise buildings in China.
