In recent years, interest in exoskeleton technology has increased in the manufacturing industry as the average age of the workplace has creeped up and with it the potential for musculoskeletal disorders. The Vest Exoskeleton (VEX) is an arm-assisting robot that allows workers to lift their arms safely and efficiently for extended periods of time. Based on the human-centered philosophy of a robotics lab, VEX enables natural arm movement, a comfortable fit, and a full range of motion through its multi-axis structure that simulates the human shoulder joint. The VEX was designed for all users. With its five modules, the VEX is easy to wear and adjust according to the operator’s body structure. The multistage arm support is interchangeable based on the user’s weight and strength and the weight of the tool. Although it is worn close to the body, its curved form and soft contact points make it practical for daily use.
