Possible applications are considered of a master-sleeve teleoperator arm system, developed in exoskeletal space suit technology, as therapeutic aid, orthotic device, or for therapy on patients with neurological disorders.
System capabilities are equivalent to mobility, dexterity, and strength of human arm. Arrangement of torque motor, harmonic drive, and potentiometer combination allows all power and control leads to pass through center of slave with position-transducer arrangement of master, and "stovepipe joint" is incorporated for manipulator applications.
Description of the current status and design features of the advanced highly mobile 8-psig-pressure Phase-I and Phase-II gloves. Advantages and shortcomings of the Phase-I glove are reviewed. The Phase-II glove is expected to provide the nearly optimum mobility and tactility required for an effective extravehicular-activity system.
Review of some of the results of a teleoperator systems technology program devoted to the development of an anthropomorphic unilateral master-slave manipulator system. Following a discussion of the mechanical design details and servo design considerations, the developed system's test results are presented.
Application of movable joints for spacesuits to orthotic and prosthetic devices is discussed. Specifications of the joints, degrees of movement, and details of construction are described. Illustrations of the equipment are provided.
Design of system to permit human performance in conditions where gravity and friction forces cannot act as counterforces is described. Application of system to performance of work in space is discussed. Diagram is provided to show construction and operation of equipment.
