This research presents an innovative pneumatic-driven exoskeleton specifically designed to enhance and assist human elbow, forearm movement. The primary objective of this study is to develop a lightweight and efficient solution that caters to individuals with compromised elbow function, including those with musculoskeletal disorders or injuries. The pneumatic connection component employed in the exoskeleton elbow facilitates the transfer of compressed air or gas to initiate and control the elbow joint’s motion and the forearm’s pronation and supination. This component comprises a compressed air source, a pressure regulator for maintaining a safe pressure level, tubing for air transportation, valves for airflow control, actuators (air muscles) responsible for converting the air pressure into mechanical motion, and a control system for operational management. By harnessing pneumatic power, the exoskeleton elbow achieves precise and controlled movement, thereby offering valuable support and augmentation to the user’s elbow/forearm motion in contexts like rehabilitation or industrial tasks. The pneumatic exoskeleton developed for elbow, forearm movement introduces novel features that enhance forearm mobility, reduce latency, and provide increased cost-effectiveness.
