Peter Lee had his arm amputated because of cancer three years ago.
This week, he got a new, top-of-the-line prosthetic arm.
During his final fitting, he talks to Rio Bennin, who also has a prosthetic arm — but Rio’s is an older model, not as nearly as fancy as Peter’s. (3 1/2 minutes)

… an I-Limb Ultra. A top of the line prosthetic, it uses sensors on his biceps and triceps to tell the new artificial hand how to move. It’s really, actually, very cool.

Feat uring 100 sensors, 26 joints, 17 motors and a tiny computer built into the palm of the robotic hand, the revolutionary Modular Prosthetic Limb (MPL) is the work of researchers at Johns Hopkins University in Maryland.

Weighing four kilograms — much like a normal arm — it can mimic almost all the same movements. “This is the most sophisticated arm in the world,” said Michael McLoughlin, of the university’s Applied Physics Laboratory.

Paralyzed Woman Controls Robotic Arm With Her Thoughts
17 December 2012

Surgeons had implanted two 4×4-millimeter grids of hair-thin electrodes in her brain to capture signals from regions involved in planning hand and arm movements.

Earlier this year, another research team reported that two tetraplegic patients had learned to grasp and manipulate objects using a brain-machine interface (BMI), as these sophisticated prosthetics are often called. This new study improves on that work by demonstrating even more fluid and natural movements—the best yet performed by a paralyzed human patient using a BMI.
