This paper is about the design of a new gravity compensator for the exo-skeleton device. The exo-skeleton devices is for increasing the torque of the human body joint for the purpose of helping the disabled or military soldiers. So far, the studied exo-skeleton device is actuated by the motors, but motors are limited in energy such that a short durability is always a big problem. In this paper. a new gravity compensator is proposed to reduce the torque load applied to human body joints due to gravity. The gravity compensator is designed using a tortional bar spring, and its structure and characteristics are studied through the test and computer simulater. Also, a design concept using the gravity compensator of the exo-skeleton device is presented.
