More than one million people are living with lower-limb amputation in the United States. The user’s control of a robotic, powered prosthesis will promote a natural gait and minimize an amputee’s energy expenditure in prosthetics use. It is challenging how the robotic prosthesis can understand user’s intent reliably so that the robot may provide adaptive support to the amputees. We propose to recognize user’s voluntary intent from the scalp electroencephalography (EEG) signal. However, one key challenge is that the EEG signal is highly complex and nonstationary, making the recognition unreliable. To breakthrough this technical barrier, we have designed and developed effective brain-computer interface integrated with advanced signal processing and machine learning technology as well as biomechanical and physiological sensor wearables. Our preliminary data demonstrate that the developed hardware and algorithms may support a reliable recognition of the user’s intent when amputees change terrain and/or locomotion.
