Remember the LUKE Arm? It is a FDA-approved robotic prosthetic arm with flexibility and strength to make life easier for people losing an upper limb. The robotic arm can be used to lift a bag and reach behind the back. DARPA is now collaborating with Walter Reed National Military Medical Center to bring these bionic limbs to veterans and service members suffering upper-limb loss.
These arms have the same shape, size, weight, and grip strength as an adult human arm. Pretty impressive if you ask us.
