Enhancing the dexterity of a robot hand using controlled slip

An analysis was performed of controlled slipping of an object within a robot hand. The possible ways an object can move within a grasp were enumerated. The set of permissible motions was found as a function of the constraint state, that is, the number, location, and types of contact on an object. The constraint state was found as a function of a number of controllable variables, such as grasping force and externally applied forces.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
