The Core of Humanoid Robots: Ball Screws and Bearings

2025 12/03

Amid the tide of modern technology, humanoid robots, as the perfect integration of artificial intelligence and mechanical engineering, are gradually stepping into our lives.
 
They not only play a vital role in fields such as industrial production lines, medical assistance, and disaster rescue, but also demonstrate boundless potential in industries like entertainment and education.
 
Behind all of this, there lies a component that seems unremarkable yet is of crucial importance — ball screws and bearings.

I. Joint Transmission: The Key to Flexibility

 

Ball screws are closely connected to the "joints" of humanoid robots and serve as one of the core components enabling their flexible movement.

Imagine this: without ball screws, every movement of the robot would become stiff and imprecise.

It is precisely the presence of ball screws that allows the rotation of the motor to be accurately converted into linear motion, thereby realizing the smooth bending and extension of the robot's joints.

Whether it is simulating human walking steps or performing complex gesture movements, ball screws play an indispensable role.
