BEIJING, Aug 26 Reuters As China seeks to race ahead in humanoid robot development, its supply chains showcased cheaper and innovative parts at the world robot conference in Beijing, but some executives warn the industry has yet to improve product reliability.

Wisson Technology Shenzhen, known for its flexible robotic manipulators, doesnt depend on motors and reducers transmission devices commonly used in robotics but instead uses 3Dprinted plastics and relies on pneumatic artificial muscles to power its robots.

This less expensive form of production allows it to price its flexible arms at about onetenth that of traditional robotic arms, said Cao Wei, an investor in Wisson through venture capital firm Lanchi Ventures, in which he is a partner.

Pliable technology will usher in robotic arms at a cost of around 10,000 yuan 1,404, Wisson said on its website.

Wissons pliable arms could be used in humanoids, said Cao, adding that the company has already provided samples to overseas companies that make humanoid robots, without elaborating.

Yi Gang, founder of Shanghaibased Ti5 Robot, a company specialising in integrated joints, highlighted some of the problems he sees in the robotics supply chain.

The whole supply chain still needs to address issues with product reliability, said Yi, adding that due to defect rates his company can only make products in volumes of up to 1,000.
