Robotic Hand with sixth sense

Researchers at Intel have developed a robotic hand, well claw, that can sense the general shape of objects before they grasp it.

Basically the principle it works on is simple if not the technology itself. The tips of the fingers send out weak electrical impulses that when interfered by objects give the finger the location of the object. Something like electrical sonar. The Intel researchers are presently calling it Pre-Touch. Wired.com has nicknamed it "Sixth-sense" which does have a catchier tune to it.
