China Wants to Solve the Hardest Problem in Robotics – Making Hands

Human hands – nimble, nerve-filled appendages that are the most flexible part of the human skeleton – are exceptionally complex. Many tasks that most people can do largely without thinking, from tying a pair of shoelaces to buttoning up a shirt, in fact require a complex set of neurological instructions and precise choreography. In thousands of years of human history, no machine has been able to truly replicate human’s greatest tool.

But now, as artificial intelligence (AI) races forwards, some companies think they are close to surpassing this final but most difficult hurdle in robotics. Most of them are in China.

A new suite of Chinese start-ups are leveraging China’s advantages in manufacturing and enthusiasm for what the government calls “embodied AI” to build the fully dextrous robotic hands that are needed to transform humanoid robots from dancing gimmicks into useful products.

Ever since Unitree’s troupe of dancing humanoids tottered on to the stage at 2025’s Spring Gala, the annual variety show televised at Lunar New Year, China has been going gaga for robots.

Technologists and policymakers see robotics as the key to unlocking China’s future economic potential as it grapples with an ageing and shrinking workforce. Marketing materials for robotic companies show their products performing all kinds of tasks that humans will supposedly soon be free of: folding laundry, cooking, cutting hair.

Beijing has repeatedly emphasised the importance of “embodied AI” in China’s development plans. In May, the Chinese Communist party’s theoretical journal, Qiushi, published a report that said “embodied-intelligence robots” were among the sectors “opening up new trillion-yuan markets”.

But although China is racing ahead in the deployment of automatons – more than half of the factory robots that are installed each year are in China – the use cases for humanoids remain minimal. “True multipurpose humanoids are far off yet,” concluded the International Federation of Robotics in a report published last September.

That is because many of the tasks that would make humanoids useful in daily settings require human-like hands. And making them is extremely difficult. Last year, Elon Musk, whose company Tesla makes the Optimus humanoid, said hands represented the “majority of the engineering difficulty of the entire robot”.
