UpperHand is an innovative and passionate group dedicated to prioritizing user experience and making an affordable product. Our group specializes in making an accessible and user-friendly prosthetic arm while streamlining the training process using electromyography (EMG) sensors and artificial intelligence (AI). The UpperHand is designed such that it can adapt to fit different arm profiles, easily perform varied hand grasps, and sustain reasonably large external loads while still maintaining a lightweight plastic structure. With the use of modern 3D printing technology, our design can keep costs low while keeping accessibility to consumers high. With a minimalist structure to the prosthetic arm, the product offers user-friendly maintenance such that it can be easily repairable in developing countries. One of the unique features of our product is the inclusion of electromyography sensors that provide an additional method for the user to interact with the prosthetic arm while also helping to replicate the experience of using an actual human arm. Our design also incorporates an AI model that utilizes pattern recognition to output the desired user hand grasp in a more reliable and efficient way. The arm is also fitted with controls corresponding to the opening and closing of the fingers, an emergency shutoff switch, and an LED indicator for the power.
