Abstract
Features for prosthetic digits are described. The digits mimic natural fingers by having multiple articulating segments, for example three, that can rotate varying amounts. Rotatable and/or linearly expandable mechanical links are configured to provide the digit segments with multiple degrees of rotational freedom. The digit may have an actuator that outputs linear actuation to cause rotation of the digit segments. The digit may have an expandable proximal link to allow for variable relative rotational positions of the segments. Middle and/or distal digit segments may fully rotate independent of rotation of a proximal digit segment. The rotated digit may thus fully surround and grasp small or large objects, objects with irregular outer contours, etc.
