Abstract: Assistive healthcare technology has gained significant importance in improving the quality of life for individuals with limb loss. Prosthetic arms are designed to replicate human hand functions such as grasping, holding, and manipulating objects. However, conventional prosthetic systems rely on rigid motor-driven mechanisms, which make them heavy, expensive, and less adaptable to natural human movement. This invention proposes a pneumatic-based prosthetic arm that utilizes soft robotic actuators to mimic natural muscle movement. The system integrates Human–Computer Interaction (HCI) through lectromyography (EMG) signals, enabling intuitive control of the prosthetic device based on user muscle activity. The EMG signals are acquired from the user’s forearm and undergo preprocessing, feature extraction, and lassification using machine learning techniques to identify gestures such as open, close, and relax. The classified signals are processed using an embedded Arduino- based control system, which regulates airflow through solenoid valves connected to a pneumatic actuation system. The pneumatic actuators expand and contract using compressed air, resulting in smooth and natural finger movements. The proposed system is designed to be lightweight, cost-effective, and modular compared to existing prosthetic solutions. It eliminates the need for complex mechanical components while maintaining functional efficiency. The prototype demonstrates improved user interaction, reduced cost, and enhanced adaptability, making it a scalable and practical solution for assistive prosthetic technology.
