Can a Robot Make Itself? China Unveils a Robot Self-Assembly Line

What if a robot didn’t just work on an assembly line — but helped build the next robot on it?

At the Global Digital Economy Conference 2026, a Chinese company unveils a robot self-assembly line that allows robotic arms to assemble key parts of another robotic arm — including shoulder joints, elbow joints and forearms.

The system uses two arms working together, combining visual perception, force feedback, real-time control and motion planning to handle delicate, high-precision tasks. A final-assembly workstation then completes the full robotic arm.

Each arm is fitted with an industrial-grade dexterous hand with 21 degrees of freedom, designed to closely replicate human hand movements. High-precision tactile sensors in the fingertips provide real-time pressure feedback, while the vision system helps identify components and guide precise grasping and assembly.

With an operating precision of up to 0.2 millimeters, the setup points to a new direction for automated manufacturing: robots not only making products, but helping build more robots.
