The Sixth Project, developed by Japanese and French researchers, is an artificial robotic finger that can be attached to the human hand next to the little finger. This additional finger is unique in that it is controlled independently of the other fingers. Its operation relies on an innovative algorithm that identifies specific muscle activity in the forearm that is not involved in the movements of natural fingers. This research initiative combines expertise and international collaboration, led by Professor Yoichi Miyawaki of the Tokyo University of Electrocommunications and researchers from the French National Centre for Scientific Research (CNRS).
