The application belongs to the technical field of bionic robots, and specifically discloses a three-degree-of-freedom bionic eye driven by artificial muscles, which comprises a bionic
eye structure, the bionic
eye structure is connected with a three-degree-of-freedom flexible driving structure, the bionic
eye structure is provided with a trolley structure matched with the three-degree-of-freedom flexible driving structure, and the trolley structure comprises a trolley support, and the trolley support is provided at both ends with a trolley roller matched with the three-degree-of-freedom flexible driving structure. The bionic eye structure and the three-degree-of-freedom flexible driving structure are connected through a spherical hinge, six artificial muscles of a
rectus muscle flexible body and an oblique
muscle flexible body are matched, and under the adjustment of the trolley structure, the bionic eye has three motion postures of
yaw,
pitch and roll, not only conforms to the physiological structure and motion form of
primate eyeballs, but also can realize the flexibility and stable
visual perception ability of
primate eyeballs through
bionics.
