Most robotic hands are built with a series of individual motors in each joint, making them heavy, expensive and prone to gripping everything with the subtlety of a vice. Japan's ITK thinks it's solved those problems with Handroid -- designed with cords that mimic the muscles in our meat-paws. No motors mean it's far lighter than the standard Terminator design, and it's controlled with a glove that allows it to mirror the operator's movement as it happens. ITK wants to sell Handroid for the bargain price of $6,500 by 2013 for use in environments too dangerous for humans, but because it's so light and cheap it could also see use as a medical prosthesis. You can see how the device works in the video after the break.
