The new Transformers(2)

The three-day Shanghai robot show last month not only attracted 216 companies from more than 18 countries and regions, but also 38,572 visitors, a jump on last year's 27,371, showing the increased use of robots is capturing the public's imagination too.

Shen Hongwen, deputy general manager of Yuzhou Yilan Copper and Aluminum Industry Co Ltd of Henan province, says his company plans to invest millions in robots this year.

"A worker's wage is about 3,000 ($480, 360 euros) to 4,000 yuan a month, and is increasing.

"A robot that costs about 200,000 yuan is equally capable of doing the work of five workers, and that cost can be recovered in just one or two years."

As industrial China continues to transform and upgrade in search of better margins, the demand for robots is expected to rise, particularly in the country's manufacturing heartlands.

Traditional labor-intensive industries have been encouraged to diversify, or at the least operate in a more sustainable, environmentally friendly way.

"Industrial transformation means higher dependence on automation and precision, and the robot is the perfect tool for that," Song says.

"The Chinese manufacturing sector has huge scale and diversity, much of which needs upgrading. That's why the market is growing so quickly."

Foxconn, the major supplier of components to Apple Inc in China, has vowed to use more robots in its various manufacturing operations across the country, to replace dangerous, boring and repetitive work.

The company is building a research and manufacturing hub in Guiyang, the capital of Guizhou.

Terry Gou, its chairman, said last month that its operations in the city's new industrial park were expected to generate revenue of 50 billion yuan in 2018.

In 2011, Foxconn revealed it planned to be using a million robots in its factories within three years, and to have its factories fully automated within a decade.

Some top Chinese home appliance brands have also been employing robotic technology on a major scale.

Haier Group, the multinational electronics giant, is reported to have cut 18 percent of its workforce last year and will cut another 10,000 positions this year, due to its increased use of robots.

Midea, the privately held Chinese electrical appliance manufacturer, has also set up robot design and manufacturing teams, and already uses hundreds of robots on its production lines.

Noting the trend, the Chinese authorities have introduced policies to encourage more use of robotics.

In December, the Ministry of Industry and Information Technology issued guidelines for promoting the use of industrial robots.

And in June, at the 17th conference of the Chinese Academy of Sciences, the national institution conducting basic and applied research, President Xi Jinping stressed that "major robot manufacturers and countries are speeding up their market development, so our companies should also improve their robot-related skills".

In Qingdao, Shandong province, an industrial park has been set up dedicated to the robot sector.

Opened in May last year, it has already attracted 30 companies and startups. Its target is 50 by 2016, generating output value of about 4 billion yuan.

"The robot industry is a way of promoting the whole city's industrial transformation and upgrade," says Geng Kai, deputy director of the Bureau of Investment Promotion at Qingdao National High-tech Industrial Development Zone.

"Qingdao has a good industrial foundation. Our machinery and equipment sector, which boasts many top appliance and food brands, had output exceeding 250 billion yuan last year.

"As a coastal city, we also have good natural conditions for developing various other marine-related robots, which could work underwater."

Further south in Zhejiang province, known for exports largely dependent on low-cost labor, 36,000 local companies have already stated they plan to replace workers with machines by 2017, at a total investment expected to be more than 300 billion yuan.

Similar estimates have been published by officials in Guangdong province, the mighty export manufacturing hub in the south of China, and in Jiangsu province, home to many of the world's leading exporters of electronic equipment, chemicals and textiles.
