Title: Mechanical hands illustrated

OSTI ID:5701422

In the field of robotics, considerable effort is devoted to the development of effective multiple prehension manipulator systems. Most of these efforts have been directed toward attempts to duplicate certain functions of the human hand for industrial and medical applications. The human hand is an intricate and complex system capable of a multitude of sensory and actuation functions. It has approximately 20 degrees of freedom controlled by a large number of muscles compared to only 7 degrees of freedom for the arm and wrist. Since the primary function of a mechanical hand is to grasp or pinch different objects, not all the degrees of freedom are necessary for every robot or prosthetic device. Most practical tasks for manipulators have their special requirements and constraints which influence the design of their end effector. Consequently various hand configurations have to be designed to effectively provide the required functions for a particular application without additional complexity. The control of these functions is accomplished by suitable actuators. Miniature touch and pressure sensors which can be as small as 3 mm in size are used to control the grip. This book discusses the knowledge base in the field of robotics. It provides an excellent compilation of photographs, scaled drawings, and source material for a wide variety of mechanical hands for the user to choose from.
