What makes the Luke DEKA Arm System so compelling is that it uses electrodes attached to a user's muscles--be they shoulder, arm, leg, or whatever muscles a given patient can use--to control a five-fingered robotic hand that has movement in all five digits as well as the wrist.

According to Bloomberg, it can perform six grip patterns and detect up to ten movements from the user's brain. Users can perform a variety of tasks, including using chopsticks, picking up and eating a grape without popping it, and more.
DARPA put $40 million into the project in an effort to do right by military veterans who've lost limbs. "Think about our military personnel, who can be great beneficiaries of these devices: before DARPA made an investment in this area the best we could give back to them was metal hooks," Justin Sanchez, a DARPA program manager in the Biological Technologies office, told Bloomberg.

DEKA needs a manufacturing partner to get the Luke into mass production. Someone should really get on that pronto.
