Illustration for article titled RAPHaEL Hand Easily Grasps Heavy Cans or Fragile Light Bulbs

Not only is this artificial hand incredibly versatile, but it's based upon extremely simple mechanics.

The RAPHaEL (Robotic Air Powered Hand with Elastic Ligaments) is the brilliant tool from the minds of Virginia Tech. Like you see in the name, air drives the hand's movement without costly or bulky motors/actuators. The system requires just 60 psi, which when guided by microcontroller commands, allows the hand to open and close with precision down to the individual finger.


As you see in the clip, this design can just as easily grasp a can as a light bulb. Plus, it makes a cool pssht sound whenever you grab something. [VirginiaTech via Engadget]
