Walking and doing backflips? Humanoid robots have got that covered. But opening a water bottle or picking up a tiny screw? That's where the real challenge begins. The human hand has 27 degrees of freedom and 34 muscles. Building a machine hand that works like a human one, known as the dexterous hand, is exactly what engineers call "the last centimeter" of embodied AI. Chinese companies are turning this vision into reality, powered by self-developed core components, integrated supply chains, and advanced AI models. They are building dexterous hands that can truly sense and manipulate. Follow CGTN's reporter Guo Linjie to see how China's smart manufacturing is closing the gap between AI and the physical world.
