The Revolutionizing Project was undertaken to develop an advanced 23-degree-of-freedom upper-limb prosthesis. The project was jointly undertaken by JHU's Biomedical Engineering Department and APL to provide better finger control. It mainly focused on developing algorithms where researchers in both research agencies concentrated on developing signal-analysis (SA) algorithms for decoding motor cortex signals associated with finger movement. Researchers in APL's Air and Missile Defense and National Security Departments focused on developing feedback control algorithms for driving the electromechanical hardware making up the prosthetic hand. A novel hierarchical classifier was used to asynchronously decode movement using neuronal spikes and sending command signals to control algorithms running on embedded processors in the prosthetic device.
