Humanoid Robot Linear Actuator

Ultra-compact, high-force-density inverted roller screw actuators designed as drop-in replacements for humanoid joints and mobile robotics.

Target Buyer:R&D Teams and Robotics Hardware Engineers pushing the limits of joint torque and envelope size.
Ultra-compact humanoid robot linear actuator

Best Fit

  • Humanoid knee and hip joints
  • Exoskeleton load-bearing actuators
  • Mobile robot lifting mechanisms

Review Before Sizing

  • Thermal management in uncooled environments
  • Weight reduction via aluminum/titanium housings
  • Backdrivability vs holding torque trade-offs

Solution Highlights

  • Industry-leading force-to-weight ratio
  • Integrated frameless motors and absolute encoders
  • Inverted architecture for minimal axial footprint

Common Use Cases

  • Humanoid knee and hip joints
  • Exoskeleton load-bearing actuators
  • Mobile robot lifting mechanisms

Implementation Focus

  • Thermal management in uncooled environments
  • Weight reduction via aluminum/titanium housings
  • Backdrivability vs holding torque trade-offs

RFQ Preparation Checklist

  1. Target actuator weight and envelope dimensions
  2. Peak dynamic load and expected impact forces
  3. Frameless motor integration requirements

Risk and Mitigation

  • Shock damage during robot falls: Roller screw architecture withstands significantly higher impact loads than ball screws without brinelling.

Factory Validation Evidence

  • Roller screw architecture withstands significantly higher impact loads than ball screws without brinelling.

Buyer Decision Notes

  • Target actuator weight and envelope dimensions
  • Peak dynamic load and expected impact forces
  • Frameless motor integration requirements
