EMG-Controlled Robotic Hand Prosthesis: Towards a Functional, Affordable, and Scalable Solution for Individuals with Amputations

This article presents the design, development, and implementation of a robotic hand prosthesis controlled by electromyographic (EMG) signals, aimed at individuals with partial amputations. The proposed solution establishes an intuitive interface between the remaining forearm muscles and a robotic structure capable of replicating complex finger movements. The system incorporates surface EMG sensors, efficient signal processing algorithms, and cost-effective actuators based on servomotors. Performance is evaluated in terms of accuracy, response time, and robustness against electromagnetic noise, achieving a 90% fidelity in motion replication and response times under 100 ms. This proposal represents a functional, affordable, and scalable alternative with the potential to democratize access to high-functionality prostheses in low-resource settings.
