Design and Development of a Bionic Arm with an Extended Range of Motion and Low Cost

Abstract

The conceptual framework presented in this study radically alters the way that prosthetic hand construction is traditionally understood. This paradigm shift promises a more natural and intuitive user experience by taking inspiration from the subtleties of the movement and functionality of the human hand. Through the use of underactuated mechanisms, which replicate the natural interactions between tendons, joints, and muscles, a prosthetic hand can be made to perform a wide range of grips and motions similar to those of its biological counterpart. This invention's foundation is not only its theoretical structure but also its physical form a crude but functional prototype. This prototype proves that this innovative approach is both feasible and useful. Because of its reasonable cost, advanced prosthetic technology is now more accessible to a wider range of users than it was in the past. This represents a significant departure from the high price tags associated with such technology. This innovative research rethinks prosthetic hands by prioritizing affordability over functionality. It takes more than a single prototype to bring about a paradigm change that will enable more people to obtain advanced hands. This work paves the way for a future in which prosthetics offer enhanced capabilities, empowering a wider range of users by removing financial barriers.
