Patent abstract
Features for a prosthetic digit actuator. The various systems and methods allow for smaller volume actuators, which in turn allows for smaller digits and/or more space for other features of the digit. The actuator includes a motor that causes rotation of a worm gear along a fixed worm wheel. The worm gear is unibody with the output shaft. The worm gear climbs along the worm wheel to cause rotation of a digit or digit segment. The arrangement of the actuator parts allows for transmitting axial forces in first and second directions corresponding respectively to performing opening and closing rotations of the digits.
