BARCELONA—Xiaomi Automobile Co., a subsidiary of a Chinese consumer electronics manufacturer, is using humanoid robots to assemble electric vehicles at is factory in Beijing. According to a CNBC interview with the company’s president, Lu Weibing, at the Mobile World Congress tradeshow, the automaker is using the machines to install nuts on a chassis production line. Additional applications being studied include bin picking and badge installation.

Weibing claims that a pair of the company’s proprietary CyberOne robots recently ran continuously during a three-hour test in the factory, achieving a 90 percent success rate. They retrieved self-tapping nuts from an automated feeder and placed them onto a positioning fixture for tightening. Xiaomi produces the SU7 sedan and the YU7 sport utility vehicle at the state-of-the-art factory.
