Overview

The Modular Prosthetic Limb is a bionic arm with human-level dexterity, weight, range of motion, and force generation. It's designed to restore full functionality to upper-extremity amputee soldiers.

Flagship features

  • Designed for individuals with upper limb amputations; controlled via myoelectric sensors on the residual limb
  • Can also be controlled via brain-computer interface (BCI) for individuals with paralysis or ALS
  • 26 moving, articulated joints — nearly as many as a human hand
  • Medium: carbon fiber, aluminum, steel, select polymers
  • Developed by Johns Hopkins University Applied Physics Lab (JHU APL) in partnership with Hunter Defense Technologies
  • Demonstrated capabilities include controlled movements, small object manipulation, tool manipulation, and clothes pin manipulation (per demo video)
