Abstract

This paper presents an experimental investigation on a novel interface for high level control of robotic hands, based on selected foot movements. A prototype has been developed that integrates 4 sensitive areas, battery, and electronics for data acquisition and wireless transmission into a wearable insole. The prototype foot interface has been experimentally validated in the control of a robotic hand prosthesis. Comparative experimental trials were conducted with 10 able-bodied subjects, with both the foot interface and an EMG-based control, which represents the most advanced interface currently available in clinical implants for amputees. The results confirmed the effectiveness of the foot interface in the control of the hand prosthesis and showed a significant decrease in required adaptation and learning from the user's side.
