An Anthropomorphic Expression Robot Based on Electroactive Polymer Actuators

Abstract

The invention discloses an anthropomorphic facial expression robot based on an electroactive polymer driver, which comprises a head-shaped robot composed of a skull cover, upper jaw, eyebrows, eyelids, eyeballs, lower jaw and mouth. The eyebrows and right eyebrows have independent eyebrow driving components respectively, and the eyebrow driving components drive the left and right eyebrows to move up and down and / or rotate left and right; the left and right eyelids of the eyelids respectively have independent eyelid driving components, and the eyelid driving components drive the left or right eyelids Open and close up and down; the left and right eyeballs of the eyeball part have independent eyeball drive components respectively, and the eyeball drive components drive the left or right eyeball to rotate; the lower jaw and mouth include the lower jaw, mouth and lower jaw drive components, and the lower jaw drive components drive the lower jaw to open and close. The mouth opens and closes. The range of motion of each part of the invention is the same as that of the corresponding parts of human beings, which can flexibly simulate various basic human expressions, and has the advantages of light and compact structure, no noise, and low energy consumption.

Description

technical field [0001] The invention relates to the field of anthropomorphic robots, in particular to an anthropomorphic expression robot based on an electroactive polymer driver. Background technique [0002] With the development of artificial intelligence, the application of robots is becoming more and more extensive, the research on robots is getting deeper and deeper, and the requirements for anthropomorphic robots are getting higher and higher. The expression robot is an intelligent robot that can simulate human facial expressions and emotional actions. The mechanical expression robot demonstrates the imitation of the robot through the interaction between the participants and the robot, making the communication between the robot and the human more natural and the communication experience better. In the field of human-computer interaction, expression robots have important significance and functions. However, most of the driving parts of the robot expression robots in th...

AI Technical Summary

Problems solved by technology

However, most of the driving parts of the robot expression robots in the prior art are driven by motors (such as the published invention patent CN 201821018065.9), which has too much sense of motion faults, resulting in stiff expressions, inflexible rotation, and unsatisfactory anthropomorphic effects

And because of the motor drive, each movement requires a separate motor and motor controller, which has the problems of large energy consumption, too large overall mechanism, heavy weight of multiple motors, and difficult control and maintenance.
