Have you ever wondered if five fingers is really enough? The folks at MIT have. Researchers in the institute's department of mechanical engineering have created a robotic glove that adds two additional digits to the standard human claw, positioning two long fingers on either side of the hand. It's ridiculously easy to use, too. "You do not need to command the robot, but simply move your fingers naturally." Ford Professor of Engineering Harry Asada says. "Then the robotic fingers react and assist your fingers." The glove's movements are based on biomechanical synergy, the idea that each finger reacts to the movements of its peers - if you try to grasp a bottle, the glove's extra fingers will try to help.
