This year's China International Robot Show (CIROS) took place in Shanghai's National Exhibition and Convention Center.

Over 2,000 robots, including industrial robots, service robots and specialist robots, went on display at the three-day event, from July 8-11.

Qu Daokui, director-general of the China Robot Industry Alliance, said that humans should make good use of robots but also be aware of their negative effects.

"Now we think that technology is a double-edged sword. On one hand, we should let robots contribute to social development. On the other hand, we should reduce their negative effects to a minimum."

Service robots have been popular at the show.

The current market size of service robots is nearly $2 billion despite the fact that service robots haven't been used in everyday life for very long.

Gao Feng, a professor at Shanghai Jiao Tong University, said that it will have dramatic growth in the near future.

"The technology of industrial robots is already quite mature at the moment. They are widely applied in the production of power generators, monitors, drives, processors and so on. These robots have been standardized and can be purchased all around the globe."

This is the fourth annual CIROS show since its foundation in 2012.
