Research: Using the xARM EEG approach for exoskeleton/prosthesis control

Mentor: Summer Science Program & MITES Semester

Abstract:

Globally, only 5–15% of the 35–40 million individuals who need prosthetics have reliable access, primarily due to high costs and limitations in current prosthetic technologies. Even among users who do have access, abandonment remains common because of discomfort, lack of sensory feedback, and insufficient control. To address these challenges, this project explores the development of a more responsive and accessible brain-machine interface that uses electroencephalography (EEG) to control a robotic prosthetic arm. By leveraging the xArm UNO robotic arm and the EMOTIV Insight EEG headset, we aim to create a custom Python-based software system capable of interpreting beta brain waves—associated with motor commands—from the user’s motor cortex. After resolving various integration and software compatibility issues, including implementing Python libraries and open-source GitHub resources, a communication pipeline between the EEG headset and the robotic arm was established. The headset captures EEG signals, which are processed and converted into real-time commands for the robotic arm. This study builds on prior EEG-controlled robotics research and attempts to scale it slightly beyond basic prototypes. By improving response time and control accuracy, this research seeks to strengthen trust in neuro-controlled prosthetics and promote the long-term goal of making advanced prosthetic technology more affordable and adaptable.
