Double eyelid eye part movement mechanism of bionic robot

Abstract

The invention relates to a double eyelid eye part movement mechanism of a bionic robot, which comprises a bottom plate, a left eyeball, a right eyeball, an upper eyelid and a lower eyelid, wherein a rotating shaft is installed above the bottom plate, the two eyeballs are hinged with the rotating shaft and can axially swing along the rotating shaft, and an eyeball up-and-down movement mechanism installed on the bottom plate drives the rotating shaft to rotate so as to realize the up-and-down movement of the eyeballs; an eyeball left-and-right rotation mechanism installed on the rotating shaft drives the eyeballs to axially swing along the rotating shaft so as to realize the left-and-right movement of the eyeballs; and the upper eyelid and the lower eyelid are connected with the rotating shaft in a rotary way, and an eyelid movement component installed on the bottom plate drives the upper eyelid and the lower eyelid to move in opposite directions so as to realize the opening and the closing of the upper eyelid and the lower eyelid. The invention can realize abundant and more vivid eye part actions, can be used as a man-machine interactive research platform for installation and has simple structure and low manufacturing cost.

Description

technical field [0001] The invention relates to a bionic robot eye movement mechanism, in particular to a bionic robot eye movement mechanism with double eyelids. technical background [0002] Since the 20th century, great achievements have been made in the research of robots, and its application fields involve all aspects of human life, such as industrial production, sea and air exploration, military affairs, hospitals, families and some service industries. At present, international research on bionic robots mainly focuses on robot perception, bionic multi-fingered dexterous hands, bionic gait, and autonomous behavior. There are relatively few studies on robot faces and expressions. When people express their emotions, the use of words often only accounts for 7%, while the tone of voice accounts for 38%, and the remaining 55% is completed by expressions and movements. Therefore, when bionic robots are applied in the service field, the importance of studying facial expressio...

Problems solved by technology

[0003] There are two main ways to realize the expressions of bionic robots: 1) According to the principle of human expressions, the human head is composed of bionic skulls, bionic organs, bionic muscles, bionic skin, etc., and artificial muscles are used to drive and generate expressions. , the research in the fields of bionic muscles and bionic organs is not perfect, and it is difficult to realize and the cost is high; 2) From a mechanical point of view, the expression of the robot is realized through the movement of the eyes, eyelids, eyebrows, and jaw. This method is simple and easy, and the cost is also low

Comprehensive analysis of the existing bionic robot eye mechanism, most of which are single eyelid mechanism, and the expression is relatively monotonous
