Delicately handling a pretzel, the robotic hand developed at the Deutsches Zentrum für Luft und Raumfahrt (German Aerospace Center), in the countryside outside Munich, Germany, demonstrates the power of a control technique called force-feedback. To pick up an object, Max Fischer (in control room), one of the hand's developers, uses the data-glove to transmit the motion of his hand to the robot. If he moves a finger, the robot moves the corresponding finger. Early work on remote-controlled robots foundered when the machines unwittingly crushed the objects they were manipulating.
