Robots dance it up at metal exhibition

The KUKA robots might be experts on assembly lines, but they are pretty good on the dance floor, too.

At the 13th China Metal and Metallurgy Exhibition, which opened on Thursday in Chongqing and lasts until Saturday, two KUKA robots dressed up and danced to the music of Peking opera.

The three-day exhibition attracted 972 enterprises from 25 countries and regions to display their iron and steel products, raw metals, processing equipment and technology.
