(Yicai) Sept. 23 -- At the opening ceremony of the 48th WorldSkills Competition in Shanghai yesterday, humanoid robots joined performers on stage, working alongside them in a show that wowed the audience.

Yicai spoke with researchers on site and the VP of Chinese robotics company AgiBot's general business unit to explore what happens when technology and human skills come together, and how robots could ultimately expand what people are capable of achieving.
