The LUKE Arm

The LUKE arm is an advanced prosthetic arm that has up to 10 powered degrees of freedom including a powered shoulder, humeral rotator, and multi-movement wrist. The LUKE arm incorporates the latest technology in electronics, motors, batteries, and materials. The arm offers state-of-the-art flexibility, strength, and dexterity to provide greater independence for people with forearm through shoulder-level amputations.

The LUKE arm was developed by DEKA as part of the Defense Advanced Research Projects Agency’s (DARPA) Revolutionizing Prosthetics program with additional funding from the U.S. Army Medical Research and Materiel Command through a contract with the Army Research Office.

Mobius Bionics is excited to be able to bring this innovative technology from the research lab to amputees everywhere. To learn more about Mobius Bionics LLC or the LUKE arm, visit
