Problems solved by technology

[0003] Most of the existing bionic eye devices are driven by mechanical transmission. Although the control is relatively simple, the mechanical structure is complex, the transmission accuracy and positioning accuracy are not high, and it cannot meet the needs of certain high-precision movements. make a lot of noise
However, for some flexible-driven bionic eye mechanisms, there is often a problem of insufficient rigidity.

Embodiment 1

[0029] A 3-DOF bionic eye movement device based on magnetic levitation drive, such as figure 1 and figure 2 As shown, it includes the bionic eyeball 1 and the three-degree-of-freedom spherical parallel mechanism that drives the bionic eyeball 1 to rotate. The camera 11 is embedded inside the bionic eyeball 1; Above: The three-degree-of-freedom spherical parallel mechanism drives the bionic eyeball 1 to rotate through magnetic levitation.

[0030] The three-degree-of-freedom spherical parallel mechanism includes a motion platform 2 fixed at the bottom of the bionic eyeball 1, a magnetic levitation guide rail 4 located below the motion platform 2, and three arc-shaped drive rods with the same structure and size connecting the magnetic levitation guide rail 4 and the motion platform 2 3. The bottom ends of the three arc-shaped driving rods 3 are all connected to the magnetic levitation guide rail 4 through the corresponding sliders 5 one by one. The magnetic levitation guide r...

Embodiment 2

[0038] Utilize the 3-DOF bionic eye movement device based on magnetic levitation drive in embodiment 1 to adjust the method for bionic eye movement, such as Figure 7-9 As shown, the details are as follows:

[0039] At the initial position of the bionic eyeball 1, the central axis of the bionic eyeball 1 is perpendicular to the horizontal plane; Figure 7 and Figure 8 As shown, the upper and lower ends of each arc-shaped driving rod 3 are respectively connected with the connecting pair 21 fixed on the motion platform 2 and the rotating pair 52 fixed on the slider 5, and the connection of the same arc-shaped driving rod 3 is connected. Vice 21, rotation vice 52 are arranged alternately.

[0040] When the field of view of the bionic eyeball 1 needs to be adjusted, the magnetic levitation control system 41 is used to control the direction and magnitude of the magnetic force of the guide rail magnetic sheet, and to control the attraction, repulsion and force strength between th...
