Problem
Humanoid robots and high‑load industrial machines require compact, ultra‑precise linear transmission components. Existing solutions such as traditional ball‑screws or trapezoidal screws are either too large, lack the necessary load capacity, or involve long lead times and high costs, limiting scalable production of dexterous robot limbs and joints.
Solution
Nous Robot designs and manufactures planetary roller screws and integrated linear actuators in‑house to serve as the optimal linear transmission solution. By leveraging proprietary high‑precision metal‑forming processes, the company produces C5‑grade planetary roller screws down to a 1.5 mm diameter—the world’s smallest—while maintaining load capacities up to 8000 N and a service life exceeding 3 million cycles without overheating. These screws are combined with brushless hollow‑cup motors into compact actuator modules for dexterous hands, robot arms, legs, and heavy‑duty industrial equipment. The fully integrated, ready‑to‑install modules reduce part count, shorten assembly time, and lower overall system cost, enabling faster, higher‑volume robot manufacturing.
Target Audience
Primary customers are humanoid robot manufacturers needing high‑precision, high‑load joint transmission for dexterous hands and limb actuators, as well as industrial robotics, automotive chassis (EMB steering/braking), medical devices, and semiconductor equipment makers requiring compact, reliable linear motion solutions.
