A small size camera assembly or micro-intelligent eye of the invention is formed of a spherical member operating as a rotor, a camera body embedded in the spherical member, and a driving device attached to the spherical member for rotating the same. The camera body has a front end and is situated on a diametrical line of the spherical member such that the front end is disposed at least on an outer surface of the spherical member. The driving device and the spherical member constitute a spherical supersonic motor, so that the spherical member can be smoothly moved as desired.
