China robot conference spotlights the changing face of humanoids

Beijing — 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, doesn’t depend on motors and reducers - transmission devices commonly used in robotics - but instead uses 3D-printed plastics and relies on pneumatic artificial muscles to power its robots.
