Eyeball motion simulation mechanism

Abstract

The invention relates to an eyeball motion simulation mechanism. In the mechanism, an eyeball connecting rod bracket is mounted on a body frame; an eyeball connecting rod is connected with a double-ended stud and fixed on the eyeball connecting rod bracket; an eyeball is mounted at the front end of the eyeball connecting rod; the rear end of the eyeball connecting rod is respectively connected with a horizontally rotating semicircular shaft and a vertically rotating semicircular shaft which are respectively mounted on a rotating shaft lower bracket and a bearing shaft lower bracket; a horizontal rotating shaft and a vertical rotating shaft are respectively connected with a horizontal driving steering engine and a vertical driving steering engine by couplings; the horizontal driving steering engine and the vertical driving steering engine are respectively fixed on the rotating shaft lower bracket and the rotating shaft upper bracket by a horizontal driving steering engine bracket and avertical driving steering engine bracket; the rotating shaft lower bracket is fixed on the body frame. The invention separates the horizontal motion and the vertical motion of the eyeball, has simplestructure, arranges all the motion mechanisms behind the eyeball, more vividly simulates the motion of the human eyeball, not only can separately rotate the eyeball horizontally or vertically, but also can combine the horizontal rotation and the vertical rotation, thereby solving the problem of motion interference.

Description

technical field [0001] The invention relates to a robot movement mechanism, in particular to a human eyeball movement mechanism. technical background [0002] Among the existing robots involving humanoid facial expressions, the WE4 robot developed by Waseda University in Japan is equipped with two color CCD digital cameras at the eyes. Hansen Robot Technology Co., Ltd. of the United States cooperated with the Korean Institute of Science and Technology (KAIST) to produce the robot "Einstein". There are 31 degrees of freedom in the head, 28 degrees of freedom for facial expressions, and 3 degrees of freedom in the neck. Spend. The "Kansei" robot of Meiji University in Japan can imitate 36 facial expressions of humans, and the EveR-1 facial expression robot developed by South Korea can make expressions of joy, anger, sorrow and joy. The designs of these facial expression robots all focus on the design of facial expressions, and the movement of eyes is relatively simple, and s...

AI Technical Summary

Problems solved by technology

The shortcoming of this movement mechanism is that the mechanism is relatively complicated, the driving mechanism is directly designed at the eyeball, and the shape cannot be similar to that of a human.
