Embodiment 1

[0038] A three-degree-of-freedom bionic eye driven by an airbag, its structure is as follows Figure 1-Figure 2 As shown, it includes a hemispherical bionic eye, and a three-degree-of-freedom driving mechanism is provided on the hemispherical bionic eye. The three-degree-of-freedom driving mechanism includes a platform fixed base plate 7, and a linear drive structure and a flexible drive structure that cooperate with each other are provided on the platform fixed base plate 7. Both the linear driving structure and the flexible driving structure are connected with the hemispherical bionic eye. The hemispherical bionic eye includes a hemispherical bionic shell 1, an image collector 11 is provided at the end of the spherical side of the hemispherical bionic shell 1, and a bionic bottom shell 3 is provided on the plane side of the hemispherical bionic shell 1, and the bionic bottom shell 3 The side close to the hemispherical bionic shell 1 is provided with a shell chute; the inner ...

Embodiment 2

[0054] A three-degree-of-freedom bionic eye driven by an airbag is different from Embodiment 1 in that: the airbag support ring 14 is fixedly connected to the telescopic airbag; the support ring connecting rod 15 is a telescopic connecting rod; The stretching and movement of the airbag drives the support ring connecting rod 15 to expand or contract, so as to facilitate the continuous fixing action of the linear telescopic airbag 13 and the flexible telescopic airbag 4 .

Embodiment 3

[0056] An airbag-driven three-degree-of-freedom bionic eye is different from Embodiment 1 in that: the side of the platform fixing bottom plate 7 away from the airbag support frame 6 is provided with a trachea groove that is loosely matched with the trachea 8 .

Abstract

The invention belongs to the technical field of bionic robots, and particularly discloses a three-degree-of-freedom bionic eye driven by an air bag. The three-degree-of-freedom bionic eye comprises a hemispherical bionic eye body, a three-degree-of-freedom driving mechanism is arranged on the hemispherical bionic eye body, and the three-degree-of-freedom driving mechanism comprises a platform fixing bottom plate. A linear driving structure and a flexible driving structure which are matched with each other are arranged on the platform fixing bottom plate, and both the linear driving structure and the flexible driving structure are connected with the hemispherical bionic eye body. A linear air bag driver and a flexible air bag driver are driven by air, so that the semispherical bionic eye has the three-degree-of-freedom movement adjusting capacity, the air mode is adopted for adjustment, and the platform fixing bottom plate is adopted for integrated bearing, so that the three-degree-of-freedom bionic eye has the characteristics of low noise, light weight, simple and compact structure, convenience in assembly, high portability and the like, and the stability and the flexibility of target image capture are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, in particular to an airbag-driven three-degree-of-freedom bionic eye, and also relates to a method for the airbag-driven three-degree-of-freedom bionic eye. Background technique [0002] In recent years, bionics has developed rapidly, and visual bionics has become a research hotspot in frontier interdisciplinary subjects, involving neurophysiology, bionics, control science and computer science. The main application of visual bionics is the bionic eye, which is to simulate the principle of the biological eye system to construct an artificial visual system, so that it has the characteristics or functions similar to the eyes of the biological system. Because the human eye is the most advanced and the most thoroughly researched, the bionic eye is mainly to simulate the human eye. [0003] Human beings perceive more than 80% of the information in the objective world through the eyes. For robots...
