A three-degree-of-freedom bionic eye driven by flexible cables

Abstract

The invention relates to a wire-driven three-degree-of-freedom bionic eye. The wire-driven three-degree-of-freedom bionic eye comprises three parts of a power set, a support set and a transmission part. Wires at the same side are pulled through four motors, so that a camera achieves two degrees of freedom. Diagonal wires are pulled through the four motors, so that the camera can rotate around the axis of the small end of a flexible beam, and thus the camera achieves three degrees of freedom. According to the wire-driven three-degree-of-freedom bionic eye, the structure is simple, the wires and the flexible beam are adopted, a gear structure does not exist, and noises are reduced; and in addition, when the camera achieves swing degree of freedom, because of the bending effect of the flexile beam, the camera achieves translation, so that the angle of view is enlarged, and the wire-driven three-degree-of-freedom bionic eye is suitable for detection application.

Description

technical field [0001] The invention relates to the field of bionic eyes, in particular to a three-degree-of-freedom bionic eye driven by flexible cables. Background technique [0002] Vision is an important source for human beings to obtain information about the external world, and the colorful world is perceived by the system. Moreover, among all human senses, the visual system has many sensory cells, exquisite functions, complex structure, and provides the most information. Vision research is an earlier and more fruitful branch of neuroscience. It is also of great significance to endow robots with functions similar to human vision, which will greatly enhance their ability to perceive the world and adapt to the environment. Therefore, bionic eye technology is particularly important for robots. [0003] The eyes are the windows of the soul. Traditional robots are often only equipped with a camera, which cannot rotate flexibly like human eyes, giving people a very blunt f...

AI Technical Summary

Problems solved by technology

[0004] Most of the common camera platforms now have two degrees of freedom, which cannot be anthropomorphic

Most of the three-degree-of-freedom bionic eyes are based on mechanical structures, which are often heavy, bulky, noisy, and have limited application scenarios.
