Here's a cool demonstration of the ExoHand from Festo - it's an "exoskeleton that can be worn like a glove," where the operator's "hand movements are registered and transmitted to the robotic hand in real time."
More details on the project are listed at the ExoHand site. In terms of practical applications, the creators say the ExoHand "could provide assistance in the form of force amplification in connection with monotonous and strenuous activities in industrial assembly, for example, or in remote manipulation in hazardous environments: with force feedback, the human operator feels what the robot grasps and can thus grip and manipulate objects from a safe distance without having to touch them." In addition, the ExoHand could be used in medical applications, assisting stroke patients with their physical therapy.
