Upper torso augmentation system and method

摘要

An upper torso augmentation system configured to augment a native strength of an arm of the user by aiding movement of the arm. The upper torso augmentation system including a body chassis configured to be worn around a torso of the user, the shoulder assembly pivotably coupled to the body chassis, and an upper arm assembly pivotably coupled to the shoulder assembly, the upper arm assembly including an assisted force mechanism, wherein an output of the assisted force mechanism is adjustable via a first adjustment mechanism and a second adjustment mechanism thereby enabling the output to approximate a determined minimum assist force required for the user to move their arm through a desired range of motion, so as to minimize any excess torque produced by the upper torso augmentation system.
