Star Wars-styled robotic arm approved for mass production

Washington: DARPA, the US Defense Department`s advanced research agency, had set out to find a better solution for amputees than the metal hooks still widely used today nearly eight years ago.

Now, the Food and Drug Administration (FDA) has granted its approval to one of the projects that came from that effort: a mind-controlled prosthetic limb called the DEKA Arm, the Verge reported.

The DEKA Arm System has been affectionately dubbed "The Luke," after Star Wars` Luke Skywalker who received a robotic replacement for the hand he lost in a fight with Darth Vader in the 1980 film `The Empire Strikes Back.`

A number of other scientists and engineers around the world are working on similar devices, but this is the first such prosthetic to get FDA approval.
The prosthetic device comes from a company founded by Segway inventor Dean Kamen, and it is roughly the size and weight of an adult arm.

The arm is controlled by electromyogram electrodes placed on the remaining portion of the human arm.

Those sensors pick up electric signals from muscle movements in the upper arm, and a computer in the robotic arm can tell what type of maneuver the user wants to make.
The results are impressive: with the arm, amputees in clinical trials were able to perform tasks once thought impossible for a prosthetic limb. They could use zippers and keys, and - thanks to vibration feedback at the base of the prosthetic - they could pick up objects like grapes and eggs without crushing them.
