Abstract

The invention relates to a three-freedom-degree bionic eye comprising a motor set, a supporting set and a connection rod set. Rotating wheels are driven by three motors to push connection rods, and therefore a camera bottom plate can move, and a camera has three freedom degrees. The connection rods are hinged to rotating plates through cylinders. The connection rods are hinged to the camera bottom plate through balls. By means of hinging of different positions of the connection rods and the rotating plates, the work space of the camera is changed. By means of engagement of three encoder gears and corresponding three motor gears, the angle by which the motors rotate and the rotation speed are measured, the pose of the camera is calculated and fed back to a control system, and closed-loop control over movement of the camera is achieved. The three-freedom-degree bionic eye is simple in structure, the space occupied by the whole three-freedom-degree bionic eye is small, the work space can be enlarged, and the blind angle can be reduced.

Description

technical field [0001] The invention relates to the field of bionic robot vision, in particular to a three-degree-of-freedom bionic eye. Background technique [0002] In the field of perceptual bionics, there are two main research directions, one is to imitate human perception of the external environment, and the other is to simulate the perception function of human thoughts and movements. In the perception of the external environment, its essence is the imitation of biological vision, smell, touch, hearing and other organs. Among them, the visual system is the main means for organisms to obtain information. A typical visual bionic system is the bionic eye. [0003] With the development of science and technology, robots are more and more widely used in daily life, and bionic eyes have become an indispensable core component for intelligent robots to obtain information. Due to the small size and light weight of the bionic eye system, it can be installed on various mobile ro...
