‘LUKE’ arm is a modular advanced robotic prostheses with high level of dexterity and flexibility

Luke Arm,” whose official name is DEKA Arm System, is one of the most advanced robotic prostheses ever built. FDA approved this robotic arm for amputees after extensive research.

LUKE arm is a modular prosthetic arm that is configurable for different levels of amputation including transradial, transhumeral, and shoulder disarticulation.

DEKA Arm was created by famed inventor Dean Kamen and his team at DEKA Research and Development Corp., in Manchester, N.H., as part of DARPA’s Revolutionizing Prosthetics program. The LUKE arm offers a level of dexterity and flexibility almost unheard of in prosthesis technology. Instead of power at only one joint or, perhaps a cable-based system, LUKE arm features motors at the shoulder, elbow and hand.

What makes the DEKA Arm unique is that it can carry out multiple, simultaneous powered movements, and its wrist and fingers can adjust its positions to perform six different user-selectable grips. In addition, force sensors let the robotic hand precisely control its grasp.

The LUKE arm is a modular prosthetic arm that is configurable for different levels of amputation including transradial, transhumeral, and shoulder disarticulation. In its maximum configuration, it has 10 powered degrees of freedom including a powered shoulder, humeral rotator, and wrist flexor with ulnar/radial deviation. Multiple powered degrees of freedom can be moved at the same time.

The hand has many pre-programmed grips using four individually controlled degrees of freedom. The hand also includes a sensor that provides grip force feedback. The LUKE arm provides resistance against light rain and fine dust, allowing wearers peace of mind when using the arm outside the home.
