Problem

Serial motor stacks are holding robotics back.

Traditional robotic systems struggle with precise orbital positioning, limiting their applications in critical industries where accuracy is paramount.

The Current State: Serial Motor Stacks

01
  • Used in humanoids, robotic arms, manipulators, and more
  • Achieve 3-axis motion by stacking three motors orthogonally
  • Each motor carries the weight and torque demands of the others above it
  • Creates complex, interdependent motion systems

Industry Impact

02
  • Bulky designs that waste space and limit mobility
  • Complex kinematics requiring advanced control software
  • Suboptimal wiring prone to tangling and failure
  • Inefficient energy use due to stacked mass and heat buildup
  • High costs in development, manufacturing, and maintenance

Solution

A compact joint architecture for physical AI.

The Orbit Actuator combines the duties of multiple motors into a powerful joint, delivering unprecedented precision and efficiency in a compact, integrated package.
