Embodiment Construction

[0020] Referring to the accompanying drawings, the three-degree-of-freedom bionic eye based on series and parallel control includes: eyeball 1, base plate 2, vertical support 6, horizontal support 7, motor drive part 5, upper four-bar linkage mechanism 3 and right four-bar linkage mechanism 4;

[0021] The eyeball 1 is a spherical cavity structure composed of an anterior eyeball 20 and a posterior eyeball 21; The axis translates and can only swing up and down or left and right, and the center position of the eyeball remains unchanged; the front eyeball seat 22 and the rear eyeball seat 23 are both fixed on the base plate 2; the eyeball 1 is provided with a third motor inside, and the third motor is used to drive the eyeball 1 The image acquisition sensor inside rotates along the direction of the optical axis of the eyeball 1, where the serial control of the rotational freedom is realized; a dial 24 is provided at the center of the outer wall of the back of the eyeball 21;

Abstract

The invention belongs to the technical field of bionic robots, and particularly relates to a bionic eye, in particular to a three-degree-of-freedom bionic eye based on series-parallel control. According to the technical scheme, a substrate is fixed to a vertical bracket; the vertical bracket is fixed to a horizontal bracket; an eyeball is arranged on the substrate; leftward and rightward motion of the eyeball is realized through an upper four-bar mechanism; upward and downward motion of the eyeball is realized through a right four-bar mechanism; a third motor is arranged inside the eyeball; and the third motor is used for driving a sensor to rotate along an optical axis of the eyeball. Through a simple bar parallel mechanism, pitching and orientation rotation of a bionic eyeball can be realized, and spinning motion of the bionic eyeball along the optical axis is realized; higher positioning accuracy of the bionic eye can be realized through three-degree-of-freedom motion.

Description

technical field [0001] The invention belongs to the technical field of bionic robots, in particular to a bionic eye. Background technique [0002] Eyes are one of the most important organs of human beings. Humans obtain objective world information mainly through eyes. For a bionic robot, the "eye" is also an important sensing device, providing a pair of eyes for the robot, which can improve the robot's autonomy and environmental adaptability. Therefore, the study of robotic bionic eyes is a research hotspot in the field of robotics today. [0003] The movement mechanism and anatomy of the human eye show that the human eye is approximately spherical and is located in the orbit. Each human eye has 6 muscles and three degrees of freedom. The eyes do not move independently, but perform conjugate motion (saccade motion, smooth tracking), anisotropic motion (convergence motion, divergence motion), steady motion under neural control. Gaze movement (tremor, microsaccade, slow dri...
