The LUKE Arm is a wonderful robotic prosthetic arm that makes life easier for people suffering upper-limb loss. It has the same size, weight, shape, and grip strength compared to an adult human arm. Users will be able to reach overhead and behind the back. They can pick objects and get things done with more independence.
The good news is DARPA is collaborating with Walter Reed National Military Medical Center to make LUKE Arms available to wounded warriors. This is developed by Mobius Bionics.
