Robotic arm may help disabled people

I'm usually avoiding to blog about robotics on this blog, althought robotics is one of my favourite tech areas.
I have seen a lot of news/articles about robotic arms, but this video just striked me. It shows functional tests of a robotic arm from DEKA (still in development) and it looks pretty amazing.
They called it the Luke's arm, because its creators was inspired by the artificial arm of Luke Skywalker from the Star Wars movie.
