Bionic Arms - TechKnow HD

The i-limb Ultra Revolution is one of the most sophisticated bionic hands on the market. It allows users to move through a series of grips and even rotate the thumb. Six internal motors allow each finger to articulate independently. The user can ultimately move through 24 different grips, with a grip force of up to seven pounds. It’s the closest many patients can come to the dexterity of a natural hand. For more TechKnow: http://america.aljazeera.com/watch/shows/techknow.html
