Abstract

The invention discloses an eye action control structure of a robot, which comprises a control assembly, the control assembly comprises an action air bag, a liquid bag and an electric hydraulic pump, aclosed air cavity is formed in the action air bag, the liquid bag is arranged in the action air bag, and the liquid bag is connected with a liquid storage cavity through a guide pipe to form a closedcavity; the motor driving part controls the cavity body of the liquid storage cavity to be enlarged or shrunk, the volume of the liquid storage cavity is increased or decreased to be shrunk or expanded corresponding to the liquid bag so that the action air bag can be shortened or extended, and the action air bag is embedded into the simulated skin and arranged in a framework of the robot. Througha gas-liquid mixing control mode, the control precision of the action air bag is improved, and the simulated skin is buffered and protected. In addition, the invention further provides a corresponding eye action control system of the robot.

Description

technical field [0001] The invention relates to a simulation robot, in particular to a robot eye movement control structure and a control system thereof. [0002] technical background [0003] Eye movement is also a kind of facial expression. When a person makes an expression, it will be accompanied by the opening and closing of the eyelids and the rotation of the eyeball. In order to make the expression of the robot more realistic when simulating humans, it is necessary to add a control structure and control system. To make the robot simulate the eye movement, the inventor disclosed a robot mouth shape control mechanism and its control system in the invention patent with the authorized announcement number CN104536374B. Changes in the robot's mouth shape. Using changes in air pressure to control the expansion and contraction of the actuating airbag is difficult to require airtightness, and because the gas is compressible, it is difficult to control the accuracy of the expans...
