Claim 1:
2. The compact bionic eye device based on a two-degree-of-freedom electromagnetically-driven rotating mechanism according to claim 1, wherein the rotor (4) is of a quartered structure like a hemispherical shell; the section formed by each quadrant segment being cut by any plane with fixed axis is a sector ring; the fixed axis, in symmetry plane of a quadrant segment and its opposite one, is the only straight line parallel to the end-face circle of the rotor; a width of the sector ring of the section is 2d and d=dmax−ηdθ/θmax, wherein θ represents an included angle of a cutting surface and a symmetry surface, dmax represents half the width of the sector ring of the section when θ is equal to 0, θmax represents a maximum value of θ, and ηd is a constant that represents that the width of the sector ring of the section decreases with an increase of θ.
