Electromagnetically driven robot eyeball device

The invention discloses an electromagnetically driven robot eyeball device. An eyeball is spherical; a permanent magnet is arranged in the eyeball or below the eyeball; the two outer surfaces of the eyeball at which the magnetic line of the permanent magnet directs are provided or drawn with two pupils of different shapes or colors; an eyeball pivot shaft is connected in a shaft hole of an eyeball bracket in a pivoting manner; an electromagnet is arranged on one side of the eyeball; a pole shoe of the electromagnet faces towards the permanent magnet. The electromagnet is electrified and excited, so the eyeball can be driven to rotate for 180 degrees, and the eyeball show the pupils of different shapes or colors.
