Robots transcend technological frontiers at Winter Olympics

With dazzling lights, a group of 24 mobile robots "danced" to music with performers in an eight-minute high-tech show on Sunday at the closing ceremony of the 2018 Pyeongchang Winter Olympics.

It was one of the world's first live performances involved such a large-scale mobile robot team and human dancers.

"The biggest difficulty is that robots are expected to perform a variety of complicated moves and be in line with the performers, lights and music," said Zhang Lei, who is responsible for developing these mobile robots at Siasun Robot & Automation Co Ltd.
