Abstract: Disclosed is an exoskeleton to support the upper extremity during manual material and tool handling tasks. This device aims to reduce the risk of musculoskeletal injuries by reducing the user's effort needed to perform common occupational tasks. The device decouples the handled load/material from the upper extremity by incorporating a bilateral cable system attached to an actuator on one end and an end-effector interfacing with handled load/tool and user's hand on the other. The user controls the device through the end-effector user interface which offers manual and automatic operation modes, with built-in sensors for regulating lifting, lowering, and holding functions. The system is capable of handling 50 lbs per side using geared DC-motors and battery-prolonging braking mechanism. Exchangeable end-effectors allow customization of the handled material/tool interface for a variety of tasks.
