Abstract: The present invention relates to an Advanced Next-Generation Myoelectric Control 3D-Printed Prosthetic Arm designed to provide an affordable, lightweight, and functional assistive device for individuals suffering from upper-limb amputation or congenital limb deficiencies. The invention addresses the limitations of conventional prosthetic systems, which are often expensive and inaccessible to a large segment of the population, particularly in developing countries. The prosthetic arm utilizes electromyographic (EMG) signals generated by residual muscles near the site of amputation to enable intuitive and user-controlled operation. An EMG sensor positioned on the residual limb detects muscle activity and converts the detected signals into electrical outputs. These signals are processed by a microcontroller-based control unit, which interprets the user's intended movements and generates corresponding control commands. A plurality of servo motors actuates the prosthetic fingers and wrist through tendon-like flexible strings, enabling gripping, releasing, and object manipulation functions. Each finger may be independently controlled, while an additional actuator provides wrist movement, resulting in multiple degrees of freedom and improved dexterity. The structural components of the prosthetic arm are fabricated using three-dimensional (3D) printing technology, preferably fused deposition modeling (FDM), with lightweight thermoplastic materials such as polylactic acid (PLA). The modular design allows easy customization, repair, and replacement of individual components. The invention provides a cost-effective, customizable, and user-friendly prosthetic solution capable of restoring essential hand functionality. By combining myoelectric control, embedded electronics, tendon-driven actuation, and additive manufacturing, the invention significantly improves accessibility to advanced prosthetic technology and enhances the quality of life of amputee users.
