1. A gear drive comprising:
a motor having an output shaft; and
gearing operatively coupled to the motor;
wherein the gearing includes:
a face gear having a toothed ridge engaging the motor output shaft, and a central sun gear; and
planetary gears engaging the sun gear;
wherein the planetary gears are nested in the face gear, between the central sun pear and the toothed ridge;
wherein the motor output shaft defines a motor output shaft axis about which the motor output shaft rotates;
wherein the axis intersects the sun gear, with the motor output shaft axis substantially perpendicular to a sun gear shaft axis of the sun gear; and
wherein the motor output shaft axis also intersects a volume swept out by the planetary gears as the planetary gears rotate about the sun gear.
