1. A mechanical digit comprising:
a base;
a first phalanx;
a first rolling surface joint that rotationally mechanically couples the first phalanx to the base for rotation about one or more axes;
a second phalanx;
a second rolling surface joint that rotationally mechanically couples the second phalanx to the first phalanx for rotation about one or more axes;
a third phalanx;
a third rolling surface joint that rotationally mechanically couples the third phalanx to the second phalanx for rotation about one or more axes; and
a flexible printed circuit board that extends between the base and the third phalanx and which wraps partially about each of the first rolling surface joint, the second rolling surface joint, and the third rolling surface joint.
