Summary of the technique:

1. Surgically reconfigure amputees nerves that once controlled the arm and the hand so they are compatible with their pattern recognition scheme

2. Teach the pattern recognition system to respond to patients neural stimuli to said nerves : “We use pattern recognition algorithms to identify individual muscles that are contracting, how well they communicate with each other, and their amplitude and frequency,” Chi explained. “We take that information and translate that into actual movements within a prosthetic.”

3. Attach the robotic hands to the patient.

Here is what I keep thinking when I see these prosthetics.

After you train to control the arm while it's attached, can you more it around regardless of it being actually connected to your shoulder (assuming of course the sensors stay in place) and move it around like thing.

Must not have watched the video:

This part of the video shows the arms are not attached. I'm sure he was trained to use the arms when they were not on him first.

This is amazing.

There is no direct connection to his brain, so he may not b controlling the arms by just 'thinking'. It looks like almost using smaller muscles to control the arms, but using the nerve connections themselves. Also, he controls one pivot per action - so he moves the shoulder, then the forearm, then the hand, then the fingers with rests between each step.

This is the one thing I didn't get: if it's mapped to nerves why can't he do two pivots at a time? Is it a limitation of the robotics?
